How to distinguish clock errors and orbit errors from satellite anomaly

Abstract

In this paper, we analyze the influence of the satellite orbit error due to changes in the reference station position. We generalize and present error change according to a distance of the baseline among reference stations. The analysis is based on the simulator. We set the position of each reference station and generate a GPS signal that includes satellite orbit error by using a Spirent GNSS signal generator. And we collect a generated signal by using a NovAtel receiver. The result can be used to distinguish between the clock errors and orbit errors from satellite anomaly. Also, it is applied to analysis of the GNSS signal anomaly based on real signal, or modeling of the satellite anomaly for other GNSS applications. is based on the simulator.
