Satellite Navigation and Communication

A satellite navigation or satnav system is a system that uses satellites to provide autonomous geo-spatial positioning. It allows small electronic receivers to determine their location  (longitude, latitude, and altitude/elevation) to high precision (within a few centimetres to meters) using time signals transmitted along a line of sight by radio from satellites. The system can be used for providing position, navigation or for tracking the position of something fitted with a receiver (satellite tracking). Satellites communication is utilized for TV, phone, radio, web, and military applications. There are more than 2,000 correspondences satellites in Earth's circle, utilized by both private and government associations
