A GPSPAC/LANDSAT-D Interface (GLI) Ground Support System was built to validate the performance and to calibrate the accuracy of the experimental navigation package, GPSPAC, flown on the LANDSAT-4 and 5 spacecraft. Although the GLI system operated successfully to give the orbit information needed to validate the GPSPAC, it also detected two anomalies: one is characteristic of the GLI system and the other is characteristic of the pre-operational phase of GPS. Several methods were applied to resolve or reduce the anomalies. This paper presents a description of the problems, the methods applied to resolve or reduce them, and the results.
