摘要

As Earth observation sensors achieve higher spatial resolution,more precise satellite position estimates are required for precision pixel geolocation determination of observed images.A dual-frequency spaceborne GPS receiver capable of providing carrier phase measurements was developed for the Advanced Land Observing Satellite (ALOS)that required stringent position determination accuracy and it has been operated successfully on orbit.In addition,full-rate observation data by the GPS receiver have been downlinked with 24 hour coverage everyday for ground-based precision position determination.This paper reports the design and flight data analyses of this GPS receiver,including long-term health monitoring for the past three years.Assessment of on-board navigation accuracy,measurement accuracy,ionospheric delay,and multi-path errors are specifically addressed.Mitigation efforts for initially observed anomalies are also described.
