DORIS - A precise satellite-positioning Doppler system
Abstract
Plans are presented for flying a Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) system on SPOT platforms. DORIS is designed for precise orbit positioning for use as part of the Topex/Poseidon payload. The measurement precision of DORIS depends upon the characteristics of Ultra Stable Oscillators (USOs). Laboratory experiments testing the stability of the USOs for long, medium, and short term behavior are presented.
