A weather satellite receiver has a scanning radiometer that receives data in a linear fashion and it's perfect for home use. It gets its signals from orbiting or geostationary satellites situated 373 miles in space and help you predict the weather patterns by giving you information from the space-based satellites. The software and a demodulating board allows you an extended advantage of connecting it to a PC for improvisation. Some of its features are an built-in sensitive front tip for a noiseless transmission, a self-scanner for non-geo-synchronized very high frequency weather satellites that get weather information from polar-orbiting satellites. Weather satellite receivers have a do-it-yourself assembly component designed to serve a wider population.
Reconnaissance receivers are an Earth observation ground unit for military surveillance work that acquires data and automatically tracks satellites for data demodulation and transposition. Earth observation stations are configured to perform lifelong multiple tasks with easy modulation systems during the decoding of information time. These receivers are advanced laboratories used for acquiring secret military data, distributed to other various receiver substations for processing and analysis by spy experts around the world.
Search and rescue satellite receivers collect accurate and fast distress call data and distribute them to search authority centers. This search and rescue repeater (SARR) acts as a relay station providing the ability to process and provide distress messages at approximately 406 MHz transmission lines which in turn communicates the information to the authorities through the SARR pallet. SARR consists of a receiver and transmitter unit; the receiver gets emergency transmitters on 121.5 MHz, 406.5 MHz and 243 MHz and transmits the information as intermediate frequency bands.
The Global Positioning System (GPS) is a U.S. Department of Defense satellite receiver that is navigation-based and fed with signals from 24 space satellites into the orbit. The GPS system became available for civilian use in the U.S. in early 1980s to satisfy its high demand rate. It tells the exact position of a user or a user's property and tracks the signal transmission and delivery times. The GPS calculates the distance of the satellites and the signal source by collecting the other satellite's signals and changing it into logistical information.
