SATELLITE SYSTEM FOR NAVIGATION AND/OR GEODESY

摘要

The satellite system for navigation and/or geodesy according to the invention is provided with a plurality of MEO satellites, each comprising a dedicated clock, which are arranged in a distributed manner on orbital planes and orbit the Earth, wherein a plurality of MEO satellites, particularly eight, are located in each orbital plane. The satellite system according to the invention is further provided with a plurality of LEO satellites and/or a plurality of ground stations. Each MEO satellite comprises two optical terminals for bidirectional transmission of optical free-beam signals by means of lasers with the respectively first and/or second MEO satellite orbiting ahead in the same orbital plane and with the first and/or second MEO satellite orbiting behind. By means of the optical free-beam signals, the clocks of the MEO satellites are synchronized with each other for each orbital plane at an orbital plane time applicable to this orbital plane.
