The Shuttle Experiment NAVEX Completed on Spacelab Mission D1
Abstract
From Oct. 30 to Nov. 6 1985 the first dedicated German Shuttle I Mission Dl with the Spacelab laboratory on board took place. One of the more than 70 experiments on board was the Navigation I Experiment NAVEX. A Cs- and a Rb-clock onboard were used for the generation of PN-code navigation signals. During the experiment these clocks were compared with the ground master clock by one-way and two-way methods. In this paper a survey will be given on the progress of the experiment and on first raw data, which indicate already a satisfactory operation of the used spread spectrum technique and a very accurate confirmation of the predicted relativistic clock effects.
