Time of Day Management for Satellite Communications; Conference paper

摘要

The U.S. Naval Research Laboratory has installed GPS-based timing systems in several DSCS satellite communication facilities to support the Single Channel Transponder program. These systems were originally installed between 1998 and 2000 in 11 sites located around the world. The goals were to manage the satellite crystal oscillators to 25 microseconds and the ground cesium clocks to 5 microseconds. This paper will describe the project's progress, with results showing the time management of the satellite oscillators and the cesium-beam clocks. A Windows-compatible computer program written to facilitate the clock management will also be described.
