Satellite communication has been a very big help when it comes to communicating nationwide, out of the country and even on different planets; like when Neil Armstrong went to the moon. Different types of phases are used depending upon the level of communication; for home we may use just basic satellite communication, then you have military communication, and also a program called GIS which allow students to interact with helping on ways to perform satellite functions and know how to implement problems if they arise. Depending on the job both civilian and militant users may access satellites and their functions based off of record keeping, video, long haul activity and data communicating. Satellite communication systems are improving daily and are on a steadily upgrade climb for protection, communication and network sourcing. Satellite communication depends on the connected user and their location in which they will be able to use the satellite source and retrieve information they’re looking for.
Satellite communication through DSL and Cable still performs as a portable satellite service and allows you to connect to the variables of the world in the same type of way; whether independent or dependent links need to be access you can use both through satellite communications. Different locations that are out of reach with cable maybe accessible through DSL and wireless connection satellite connections. Cable limits a network to only being able to house information through that cable network and the bandwidth may not permit outside a level one is trying to specify. Satellite services have improved a wide range of connectivity issues, and is the massive growing force for videoing, voice transmission, data transmission and even cellular connections and transmissions. Although satellite communications have helped at home connections, in the office and in store connections, cellular connections are just becoming the interface and local way of using satellite communications. Distinguishing between different types of data connection types are LTE (4G) and the standard 3G connection. LTE allows for faster connection and no speed up wait; until 3G bouncing off of the satellites it causes slow connections and it also pulls when the apps or internet browsers are closed out of your phone. Not all places are adapted with wireless connections and due to that DSL speeds are limited because it’s only going to connect to what sources of speed you have within your household area.
Another thing that can stop DSL from functioning properly is if there are some type of services glitches within the network. DSL performs best when there isn’t any tie ups in the network, everything is functioning properly and also depending on the device you have whether it can hold a stable connection or not. Satellite communications connecting to devices allow you not need cable sources at all; if you can access the internet or make satellite communications in any type of way without using cable as a connector then you will be guaranteed good services. Two types of bandwidths that help satellite prove to be advanced are SHF (super high frequency) communications and UHF (ultrahigh frequency) communications. SHF and satellite systems support different worldwide connections with secure voice and high data rates; they connect frequent private networks through different military installations and many other government agencies including and not limited to the FBI, Police force and CBI. SHF communications allow these government agencies to connect and a faster, cleaner, and more appropriate rate whether at ground level or sea level. SHF communications systems and satellite connections are used for high priority communications and will only be heard about in warzones or when there is time for excess force to be displayed on a battlefield. SHF allows on ground preparatory personnel to communication directly via satellite to command watch in different areas of the base or nation giving them feedback on what’s happening or what needs to happen. If something is to go wrong while transmitting through SHF communications the back system DSCS will immediately and automatically take over. DSCS stands for Defense Satellite Communications System and when there is trouble with the main serve this back will kick in and continue to do the job the SHF satellite communication system should be doing; the DSCS system will also help to extend the capability and life span of communication services.
UHF connections aren’t like the SHF communications system although they provide adequate connection and faster DSL services. Signals for SHF are not like UHF; UHF signals doesn’t send information to the same platform of the atmosphere (upper) like SHF does. UHF sends there signal directly from personnel to space and back to the surface point in which it’s intended. UHF’s is used directly to satellite communication and broadcasting; it broadcast through cellular devices and through two or three party paging systems. Using UHF modes are very much practical and the portion of the radio spectrum through international telecommunication so it helps transmit vastly through the space portals.
Global technology is taking over lives on a daily basis; the platform serves a purpose more substantial than any cable you have set you. Coax wire has given computers, tablets, laptops and cell phone the proper DSL speed to beat out any type of network service band and its capabilities. Global technology is designed for nothing but the highest speed on connectivity and integration systems. One thing about satellite communication is it allows one to properly use the internet and type in any key words that will pinpoint on the global exactly what one may be talking about; using cable one may have to pay for extra services to be provided because a network using cable is limited through band, connectivity and inside/outside sources of information. An example of a great global and satellite communications system would be the AKO (army knowledge online) accounts provided for active duty military personnel’s, VETs, and some DoD workers. AKO accounts allow you to check emails, look up job related information and to also keep in contact with those in other regions and parts of the country and surrounding country. AKO counterparts are night private due to the mass production of searching, emails and browsing; most information that’s provided is open to whomever would like to search it and become familiar with it. Having open network activity doesn’t mean it isn’t monitored at all times and doesn’t mean that your network access isn’t being tracked.
Unlimited data is repeatedly used within AKO services; the Global allows for information to get to its destination with a click of a mouse and the users can create ways of being notified also with a receipt verifying recipients got it. AKO provides classified and unclassified information; when personnel are using their CAC card it allows more privileged opportunities access to classified information. Security certificates are on the CAC cards which let the networks and satellite pick-ups to pinpoint exactly who the user is, what information they’re entitled too and how much access one should have while visiting the network.
SATCOM programs provide implementation programs allowing for service workers to breech a certain amount of information before it feels the need to notify the proper government authority and give feedback on information that was looked up and used for certain task. The global provides many services that are highly dependable on satellite communication systems. Cost effective management is widely entailed when it comes to using the satellite communication systems because so much can be done on a network; although monitoring is 24/7 any information can slip through without someone knowing and access to documents, plans and maps that doesn’t need to be seen will be in someone else’s hands.
A system that caught my eye working with Southern Company is the GIS (Geographical Information System); this system allows for improvement on mainly visualization. Southern Company takes in a lot when it comes to people working for their company, they like to give people a change; those are willing to take in the lessons, focus on the task at hand and make sure that while at work the number one priority is working. GIS allows for better understanding and training methods of surveying, implementations, and seeing different dimensional graphs of hazards that can arise. This system actually allows mid aged teens to take part in learning about satellite communications and what it entails; it allows for hands on preparation when encountering an problem and it also allow for students to see different ways satellite communication works and how it’s implemented when a problem arise. Satellite communication is becoming fundamental but very well understood; especially considering people are limited to in house (region) information. The global end of satellite communication focuses solely on the flaws of cellular communication; delivery across networks are very important and if information can’t be sent and received within a matter of minutes then the system is considered as failed. Communication levels tie into the debate of cable vs wireless vs dish. Besides the demands of all information and high definition internet and television channels, no one really deals with Dish network. Although dish streams directly from satellite communication it freezes up, shuts off and the slow band doesn’t allow anyone to see what they need to or receive information in a respectable amount of time. Not everyone looks into in house staff that take out the time to develop, build, implement, and support systems. Competition is amongst the best communication systems and all different types of systems try to beat out on another when winning over people and the abilities on what it can do. Going globally and dealing with satellite communications you will not disappointed; you may be limited you but won’t be strayed away from relay instructions that are in the systems commands on what to do.
Packet and switching is what global always show the benefits of generation IP switching. The network capabilities focus on voice (commands), SMS, MMS and pre-paid and post services. Small transponders are networked with the military; they limit terminal size, rate and techniques. Also among switching over to satellite communication is low cost devices and circuit technology. Cell phone companies are now allowing pre-paid services to customers but giving them a wide range of access to communication applications through satellite; digital techniques aren’t too far behind. At first satellite communication was based solely on documentation and telephone features; not too many digital features were used but mapping and other geological pictures. However now one can send different types of vides, pictures and also be allowed to zoom in and out pinpoint any type of distress. All aspects of a network are secured through fixed services; they are also protected against jamming, intercepting and fading.
Future transmission technology services are now created with a high frequency band because of the new components that are now available for better service. Bigger, wider antennas help communication levels provide adequate connection to adapt to whatever type of network is pulling from satellite region. The satellite systems are now being designed on needs and not on what one things the system should entail. Due too many terrorist attempts and hacking successes system aren’t equipped to come ready and also on standby when they need to be. Not just military forces but other government officials use satellite communications to their best ability but they wait until they need them. Following a chain of command they limit themselves to what sources they need or use to avoid over doing a situation or not having enough resources to use all technology provided. Not too many people worry about that as an issue but they do worry about the expected future and the increased advantages and disadvantages on what satellites can provide and who outside of the government can afford access to them.
Due to the high volume of users, terrorist has been a major concern. Many enemies and their threats have shut down systems to the point of no satellite communication devices or technologies being able to transmit through land or sea. In case an emergency arises and no information can be transmitted, performs can perform a task what is called frequency hopping; it allows for higher faster transmission jamming that allows codes to be sent and received through satellite systems and encoded on the other side of the spectrum. Times slots sent through the beams must be in perfect formation, if there is any loop hold them information in the satellite spectrum risks being decoded, not sent at all or received in a distorted manner. Support for all different type of users is worldwide and global communication allow each to serve as a backup system for another depending on the threat and the fixture of the problem. The navy, army, air force and marines although different branches each department is broken down into mobilized categories that allow one to be helped when it needs to be and only that section. Doing more to satellite communication than it needs to be can hurt a system. When a system is at risk a government official can shut the system down to the lowest level of degree to where they can still function and do work but not feel a threat on hand. Global technologies can forfeit their structured designs up to the point of no longer being seen on the global but being able to fight off an attack as though they are. Due to the global of militant forces being so huge and widely used, outside of government official’s future communication through satellite will have smaller terminals. Creating smaller terminals from non-important members using band from satellite services it keeps the network moving fast but at a past that can be controlled. If officials feel that certain areas of information that is being broadcast or access is starting to pose a threat then it can be removed immediate and no danger will be done to the system, its networks, network users and out house suppliers. Organizations will try their best to achieve this at the given time. Out of country users that are no co-existent with US officials make it harder for satellite communications to operate when using out of region commands. Compromising between existing satellite networks will be widely looked at and evaluated for either change, destruction or to be left alone.
Territorial grounds serve no purpose for someone who isn’t a government official and wants to access a network; an example of this would be the new PlayStation 4 and Xbox 1 game consoles. These new consoles allow personnel to access the internet through satellite communications and it doesn’t limit who can gain that access. Right here from the US using cable or wireless the DSL is the fastest it can be giving the best reception possible. Gaming has now went mobile because of satellite abilities; the gaming network has their own integrated fields that allow systems to be hacked, trickled with and even completely broken down because they don’t really do any harm. They only harm that’s done to the satellite connection is brought about due to level change or the speed of the game moving up. Research has shown that many gamers are getting into more trouble because of the hacking of systems on certain levels of satellite premises. No system is alright to hack and due to a high volume of users, if a system is hacked so that one wants to opt to play better and instead of earning they attack the system the government and creator of the game has the authority to shut them down at any given minute.

...Mobile Teams/Satellite Clinics under UNDP-CHTDF Project Background The project covers seven upazilas of Rangamati district and four upazilas of Khagrachari district of Chittagong Hill Tracts situated at the Southeast part of Bangladesh, near the Myanmar and Indian border. This region is distinct from other parts of Bangladesh in terms of language, religion, tradition, social customs and norms, land and structure. The area is home to 12 different ethnic groups including the Bengali. Although it is resourceful with its natural beauty and cultural diversity, the real situation of the people is worse than that of other parts of Bangladesh. Access to basic services such a livelihood, education, health, water and sanitation etc. are poor and need to be addressed. Health conditions in these areas are of major concern. Malaria, Pneumonia and Diarrhoea are endemic in these districts and constitute as the highest causes of child mortality. Ante and post-natal care is uncommon in these areas. Deliveries performed by trained birth attendants are very low. CHT communities rely on traditional birth attendants (TBA) or ojhas to deliver babies. Health insecurity a major problem in the CHT, because: • Access to health facilities and quality of health care in such facilities is poor o Basic infrastructure, including roads, is poor and the terrain is mountainous.

Satellite Radio

...Satellite Radio Rhonda Stubblefield COM/150 June 23, 2012 Alain de la Brousse What have 22.3 million subscribers learned about satellite radio that the rest of us listening to traditional radio still haven’t yet figured out? The amazing advantages that are now giving satellite radio stations the power to change how America listens to music, sports, news, and comedy. In 2001 Fortune magazine named satellite radio as their product of the year. The magazine’s rationale for its selection stated: “of all the new technologies of 2001, XM Satellite Radio is way, way, way above the rest. It’s the first major advance in radio since FM emerged in the 1960’s, and the best thing to happen to mobile music since the dashboard CD player.” In addition, Lee Abrams, XM’s chief programmer, noted that the company hoped to have the same creative results as the FM revolution of the late ‘60’s and 70’s had. FM brought major changes to the radio scene. It delivered superior sound and had fewer commercials which pulled a large audience from AM radio. Abrams has argued that FM has now “sprouted a potbelly, gone gray at the temples, and become the stodgy establishment – complacent and vulnerable to a hard charging rival such as XM”. “Right now, we live in a very vanilla age, radio-wise,” noted Abrams. “Except for talk radio, its stay in the middle, don’t upset anybody, and play the big hits everybody’s comfortable with. We’re 180 degrees from that. We want to challenge people”. ......

...Title of the Case: Satellite Radio (B) Time Context or Period: 2005-2008 Summary of the Case: Late 2005 proved to be the high point of expectations for satellite radio due to the unexpected increase of subscriptions for Sirius and XM Radio that even surpassed forecasts made a year earlier. As 2006 progressed, the growth rate started to decelerate and both companies have continued to lose money. Competition in the market became stiffer because of the rapid growth of technology which led to the birth of new gadgets used in consuming music. Also, a sharp downturn was also experienced by the auto business due to the crisis felt the by the United states. Because of these factors, Sirius and XM Radio have decided to undergo a merger agreement because of the benefits that the merger offers. However, the proposed merger faced regulatory hurdles with the Department of Justice and the FCC, and oppositions from the National Association of Broadcasters (NAB). Later on, in March 2008, the Department of Justice and the FCC gave their “go signals” to the merger provided that the new company, which is named Sirius XM, to offer more content a la carte pricing which gave a huge impact on its revenue. Despite positive cash flows that the forecasts stated, Sirius XM continued to have difficulties, especially in funding current liabilities, because of the crisis felt in the automobile industry, and by late 2008, the stock of the new company was traded under $0.40 a......

In 1997, the FCC granted satellite radio licenses to XM Satellite Radio and Sirius. Since now XM has a license they can launch their product but they are facing a lot of questions that are to be answered to have that perfect launch. At top of that, XM Satellite Radio has not proven it value to the market players yet. XM’s biggest rival, Sirius is already far ahead of XM Satellite in term of publicity, timing and fund raising. XM Satellite Radio has a big challenge of getting customers to pay for a service that has been and still is free. Furthermore, people are unaware about Satellite Radio in general and how is it different from AM/FM radio. Moreover, the radio industry is basically in the sales decline stage of the product lifecycle and on the other hand XM Satellite Radio is in the introduction stage of product life cycle. XM is looking for ways to introduce their product to the market but the radio industry is basically trying to stay alive. Now XM needs to decide what should be done so that their launch is perfect from the day one. They have many issues to be resolved like choosing the manufacturers, choosing the target market, setting the price, getting the best retailer, choosing the right promotional tools etc. XM has great opportunities to enter and exploit the market and change the...

Satellite Tv

...Wil Hardeman Satellite TV The role of satellite networks in global communications is growing at an unprecedented pace. From direct broadcast satellite (DBS) television, to satellite phones, to credit card transactions, to the Internet, corporations and consumers are embracing these new services and placing demands on bandwidth. With this demand have come expectations in terms of basic service costs, hardware costs, and ease-of-use. These expectations have forced the industry to examine its traditional ways of operating in order to make satellite services as accessible and convenient as its terrestrial competitors. Recent current events, such as the World Trade Center tragedy and its aftermath, have demonstrated our need for and how reliant we have become on communication medium. As the World Trade Center lay in ruins, also destroyed were a vast array of communication equipment from transmission antennae for radio and TV stations to switching equipment for phone service. Though throughout all this people were still able to communicate, TV and radio stations were still transmitting their signal. Much of this was a result of wireless and satellite technology. Satellite television is a system of supplying television programming using broadcast signals relayed from communication satellites. The signals are received via an outdoor parabolic reflector antenna usually referred to as a satellite dish and a low-noise block downconverter (LNB). A satellite receiver then......

There will be a focus on the application of SATCOM in the U.S. Military. The U.S. Military implements SATCOM in many ways and this paper will outline some of the current uses and capabilities of the technology. This paper will explore publications on the topic of Satellite Communications and list the differences in commercial versus military uses. Current Trends of Satellite Communications and Their Application in the U.S. Military Satellite Communications is a broad sense is sending data from one point to another point by means of a satellite in orbit. A satellite, by definition, is an object that orbits the Earth. There are natural satellites and there are artificial satellites. An example of a natural satellite would be the Moon. Coincidentally, the Moon was the first satellite used for data transmission when the United States Navy successfully conducted Operation Moon Bounce in the 1950s. Since this success, we have created artificial satellites that we can place in strategic locations and use satellite communications to its full power. The first artificial satellite ever produced and launched was Sputnik 1. Sputnik 1 was launched by the Soviet Union in 1957. The satellite orbited the earth for 92 days,...

Satellite Communication in Ghana-Challenges and Prospects

...TITLE: Satellite Communication in Ghana-challenges and prospects Introduction Busy Internet is a Ghanaian ISP that uses satellite connectivity to bring Internet to West Africans. The operations of this ISP illustrate the reliability, versatility and efficiency of, VSAT, (Very Small Aperture Terminal) networks in delivering fast broadband Internet services. This paper discusses technical, economic and regulatory issues relating to satellite networks as a means of bringing Internet to Ghanaians, and the challenges confronting the country’s National Communication Authority and the Ministry of Communications. Waking up to the Call Satellite communication was not an integral part of the Ghanaian communications system until the early 1980s. Prior to 1981 communication within Ghana and between Ghana and the outside world was not very effective. The country relied on aging Plain Old Telephone Service (POTS) Lines for voice, and terrestrial microwave networks for radio, and television. International voice, video and data communications links were limited, with most of such communications services operated by the government run telecommunications monopoly. The construction of a satellite earth station at Kuntunse in the Eastern region of Ghana in 1981, and related communication reforms of the early 1990s marked a dramatic shift towards greater use of satellite communications technology over the next two decades. Satellite earth stations and connecting equipment were installed by......

British Satellite

...British Satellite Broadcasting (BSB) was a consortium originally formed by Pearson, Granada, Virgin, Anglia and Amstrad in 1986 that was awarded a license to exclusively operate UK’s first DBS channels by the Independent Broadcasting Authority (IBA). According to BSB’s early estimate, they planned to install 400,000 satellite dishes in the first year of broadcasting, 2million by 1992, and 6 million in 1995. However, the actual number of installed satellite dishes was far lower than expectations. BSB continued losing £6-7 million per week by October, 1990.Although BSB’s delayed launch of satellites and shortage of signal receivers accounted for this major setback, and Sky’s surprising entry into the market was the primary reason for BSB’s predicament. BSB’s failure to acknowledge the threat of new entrants was the preponderant factor that led to their demise. News Corporation announced in 1988 that a new satellite television venture, Sky Television shall broadcast in and around Britain. While BSB’s satellite failed to launch as planned, Sky soon went on air in 1989 by using conventional technologies and renting satellite channels thus gaining the advantage of being the first mover. Therefore, sky had a lengthy head start and maybe a modicum of a better reputation. The market that was expected to be monopolistic actually turned out to be an oligopoly.

Uhf Satellite Tool

...increasingly complex and important issue for the Navy’s operation, as the demand for the communications capacity has continuously been growing while the spectrum resources are limited. In particular, the SATCOM operation needs to reuse (in fact, has been reusing in some cases) the UHF frequency channels to accommodate the communications demand. Currently, such a UHF SATCOM channel frequency planning has been manually performed by SATCOM engineers. This paper[1] presents a UHF SATCOM Frequency Reuse Planning Tool (UFPT), which can automate the frequency planning process, maximizing the efficiency of the spectrum use. While the concept of maximizing the spectrum efficiency is not new, the planning process for the UHF SATCOM not only takes a lot of time and effort but also requires technical expertise, if the tasks are manually performed by engineers. In some circumstances, the operation may have to be content with a suboptimum solution due to a constraint on time and engineering cost. UFPT has been developed to provide technical analyses required for the UHF SATCOM frequency planning, thus saving the time, effort, and cost. One of the primary objectives of developing UFPT is to support SATCOM operation for Global SATCOM Support Center (GSSC). Currently, processing Satellite Access Request (SAR), which asks for a SATCOM channel, GSSC personnel often look into a large amount of satellite configuration data typically given in spreadsheets. Searching the SATCOM channel, they......

Communication Satellite Corp

...CASE SUMMARY NAME Charles Daugharthy DATE March 16, 2016 CASE TITLE Communication Satellite Corporation (CSC) (1) BACKGROUND: The Communication Satellite Act was created in 1962 to mandate a national policy of a worldwide communications satellite system that cooperated with other countries. Under this act, CSC, a privately held company would represent the United States. The FCC was able to regulate CSC and this was allowed due to the recently passed Communication Satellite Act. As this industry started to grow CSC requested their first rate increase which led to a FCC proceeding. First, the FCC needed to determine CSC’s required rate of return. During the proceeding, three testimonies were given, one by Dr. Brigham, Dr. Carleton, and Dr. Myers. Brigham argued for a 12% rate of return for CSC for 1964 to September 1974 and then a 15% rate increase beginning in October 1974. His calculation for rate of return was based by taking a sample of 602 industrial firms and 56 utility firms and taking an average using the discounted cash flow model. Carlton argued for a rate of return of 7% for ‘64-‘71, 8.33% for ‘72, and 9.42% for ‘75. Carlton’s calculation was based off of a comparison to AT&T and by creating a risk premium from treasury bonds. Myers suggested required rate of return of 12%. He based his from using the CAPM model. It is also important to note that CSC is an all equity firm, which means it won’t have any debt to lean against its equity. (2)......

Scada and Satellites

...use of Distributed Control Systems in Frontier Refineries as a close example of the use of a SCADA-like system in the oil industry. Implementing the capability of satellites to these systems has allowed broadening their utilization potential to other industries, including government and military defense uses within the domain of national security. This can lead us to an analysis of the financial sustainability of these systems for the-at least for now-near future. Based on what we have learned about the oil industry-the need for continuous monitoring and control of diverse assets in the plant/field-we can conclude that the basic functions-pipeline, tank and pump monitoring, leak detection, etc-are operations that will maintain steady usage in spite of fluctuating financial conditions in the oil/gas market. We expect also that, given the conditions of international relations, the military and government need of SCADA systems for anti-terrorism and peacekeeping efforts will not be affected by variations in credit markets. In fact, the more this security around this technology is developed, the more we expect security-sensitive users such as the military will make use of them. We should also consider the possibility that a shift in international relations policies might dampen the demand growth rate for SCADA/Satellite systems. The sources studied for this report also make another consideration: the uncertain and variable situation in the Middle East and Africa seriously......

Xm Satellite Radio

...Executive Summary: XM satellite is a newly established company that has the potential and the ability to become leading satellite radio service provider in United States. At the time of the case, the demand for high quality, ad-free and mobile radio had a great potential and XM along with Sirius received a great opportunity to enter into the untapped market.
