Experiment on synchronization and one-way range measurement for Spacelab missions
Abstract
The paper describes a project to develop and test a procedure for synchronization and time division with accuracy of under 100 nsec and to develop and test a one-way range measurement system with accuracy under 30 m. Highly stable cesium atomic clocks both on the ground and onboard Spacelab will be synchronized with one another in order to determine the behavior of the clock on board. Time marks in association with spatial coordinates will be transmitted from space and evaluated on earth for one-way range measurements. Accuracy requirements, measurement accuracy, instrument travel times, and propagation path effects are discussed.
