NAVEX - A Space Shuttle Experiment with Atomic Clocks

Abstract

NAVEX is a navigation and time transfer experiment. It will be flown within the payload of the first German Spacelab mission D-1, scheduled in June 1985. The objectives of the experiment are to synchronize distant ground stations with an accuracy of better than 10 nsec and to demonstrate one-way ranging with an accuracy of better than 30 m. Spread spectrum signals will be used and the related technique will be tested. On board a Cs and a Rb clock will be used. The relativistic effect of these clocks will be about -25 micro-sec per day. On the ground at least two receiving stations and one transmitting-receiving station will be installed.
