Global Positioning System GPS

Global Positioning System Description — How it Works The satellite’s position is determined by high resolution radar observations, then precision orbital parameters are determined to prepare accurate ephemerii. Many small perturbations must be included in the preparation of the ephemerii. The distance from the satellite is determined by the time it takes for a radio wave to reach the site from the satellite

GPS satellite modulation technique Each GPS satellite transmits a unique navigational signal centred on two L-band frequencies of the electromagnetic spectrum: L1 at 1575.42MHz and L2 at 1227.60MHz. At these microwave frequencies the signals are highly directional and hence are easily blocked, as well as reflected, by solid objects and water surfaces
