WebbSatellite positioning is ultimately based on the accurate transfer of time. Each of the four satellite positioning systems consists of some 20 to 30 satellites, orbiting at an altitude of approximately 20,000 kilometres. All of these satellites are equipped with a precise … WebbThe signal broadcast by the satellite is a spread spectrum signal, which makes it less prone to jamming. The basic concept of spread spectrum technique is that the information waveform with small bandwidth is converted by modulating it with a large-bandwidth waveform (Hofmann-Wellenhof et al., 2001).
