Abstract
The instant invention relates to a method for establishing a satellite navigation system, using the satellite networks provided for mobile communications, below the geostationary orbit, in particular in LEO (low earth orbiting) or MEO (medium earth orbiting) constellations, as well as its connection to communications satellites in the geostationary orbit. The establishment of satellite navigation networks in accordance with the invention is made possible by means of the employment of special optical ISL (inter-satellite link) terminals with ranging functions in various LEO or MEO satellite networks, and possibly by including GEO satellite constellations.
