ONBOARD AND GROUND GNSS RECEIVER DATA FUSION FOR INCREASING MICRO/NANO SATELLITE POSITIONING ACCURACY

摘要

Fusion of data from onboard and ground navigation receivers (NR) in the pseudo-differential mode of GNSS radio navigation aimed at increasing microanosatellite (MNS) positioning accuracy is considered. In this case, navigation measurements are received from the same constellation of navigation satellites both on the ground station and aboard the MNS while they are in the area of mutual visibility. The algorithm and estimates for improvement of potential navigation accuracy are given.
