Satellite signals are similar to microwave which require a direct line of sight to ensure proper transmission. Satellites require that a satellite is in geosynchronous orbit of the earth and receiver must be locked on satellites orbit at all times to maintain connection. Satellites can cover large areas since they are in high orbit they can relay signals through other…

Satellites have benefited our everyday lives. "Communication satellites are responsible for instantaneous television coverage of events all over the globe, for the speed of international banking and finance, for the almost-immediate delivery of vast amounts of information, and for international e-mail and telephone service to all parts of the Earth." ("Neal 186") When a person watches television, the television is sent from the station to a satellite and to a local provider. Without satellites, a person would be able to only watch local stations, but with satellites a person can watch a television program from anywhere in the world, talk to anyone, or even send e-mail.…

The Navy Multiband Terminal (NMT) Program is the next generation maritime military satellite communications terminal. The NMT Program is the required Navy component to the Advanced Extremely High Frequency (AEHF) Program for enhancing protected and survivable satellite communications to Naval forces. NMT multiband communication capabilities will communicate via two way Ka-Band on Wideband Global Satellite Communication (SATCOM) (WGS) and shipboard and submarine terminals to communicate with X-Band using the Defense Satellite Communications System (DSCS) and WGS. NMT will operate in the Extremely High Frequency (EHF)/AEHF Low Data Rate (LDR), Medium Data Rate (MDR), and Extended Data Rate (XDR) communication modes and will sustain the Military Satellite Communication (MILSATCOM) architecture by providing connectivity across the spectrum of mission areas to include land, air and naval warfare, special operations, strategic nuclear operations, strategic defense, theater missile defense, and space operations and intelligence (1). The NMT system will replenish and improve on the capabilities of both the Military Strategic and Tactical Relay (MILSTAR) system and WGS system by equipping the warfighters with assured, jam resistant, secure communications. The AEHF system will provide crosslinks within the constellation as well as between AEHF satellites and MILSTAR satellites in the backwards-compatible mode. Mission requirements specific to Navy operations, including threat levels and scenarios, are contained in the AEHF ORD. NMT will be a FORCEnet enabler by providing critical protected bandwidth for war fighter information services (3).…

Running Head: Satellite Radio Introduction Satellite radio is a more advanced substitute to terrestrial-based services. The choice of capturing radio frequencies via satellite involvement allows access to a mobile radio service. Satellite radio functions with the help of fixed-location receivers, dish antennas and signal repeaters. These commercial investments permit the listeners to enjoy hands-free communication over immense geographical areas. It provides coverage around tall buildings and bridges, in any weather, without the slightest interruption unlike terrestrial. The dish antennas and signal repeaters are invested in and set-up by the providers of the technology, to make signals or frequencies more available to listeners within a set range. Background Digital Audio Radio Service (DARS) was launched by the Federal Communications Commission (FCC) in 1992 by creating specific segments of radio frequency for satellite broadcast on radio. An auction was later held for the buying of these particular radio frequencies and two companies…

Communication satellites work non-stop 24 hours a day to keep the entire world linked together. Until recently NASA had been the only one's launching satellites, but now many private companies are benefiting from what a satellite can do. Once a satellite becomes geosynchronous, rotates with the earth orbit, a satellite is ready to work. It then beams messages to a ground station, the ground station receives these messages by using a device called a transponder. Which interrupts the message and then distributes it. By doing this satellite stations can than transport telephone service, data, or television transmissions to almost anywhere. These communication satellites are used for things like an overseas phone call or beaming 150 channels into your living room.…
