The knowledge of the orbits and clocks of the satellites is fundamental to have a right positioning. Any error in the GNSS} satellite coordinates or satellite clock will affect the positioning accuracy. Information about orbital parameters and clocks is transmitted in the navigation message. Precise ephemeris and clocks are also provided by some organisations as IGS.
In the following articles, orbital elements are defined, the navigation message is introduced, and the algorithms for satellite coordinate calculation from the GNSS (GPS,GLONASS and Galileo) broadcast and precise ephemeris are detailed.
