Abstract

Abstract: GNSS receiver technologies allied in high orbit altitudes has developed rapidly in recent years and has been used in orbit on many spacecraft. In this paper, TJS-5 Satellite is taken as an example to illustrate the design scheme of the high orbit navigation receiver based on the SoC platform, which takes the characteristics of the weak signals of GEO orbit navigation into consideration, and adopts the high sensitivity acquisition technology and the fast signal acquisition technology. Finally, the 19-day in-orbit data of TJS-5 Satellite are analyzed. The number of available satellites is between 4 and 8, the position accuracy of orbit determination is 15.8133m and the velocity is 0.012108m/s, which meets the needs of autonomous positioning and precise orbit determination in the whole orbit period of the satellite. The calculated results are compared with those of TJS-2 satellite.
