Abstract: In this paper,we analyze the single-satellite service performance,the influence of system performance when IGSO-6 joined and the influence of orbit determination of IGSO-6 satellite which firstly applies the new attitude control mode with some data between June 17,2016 and July 18,2016.The results show that the signal-in-space user range error is 1.85m;the daily stability of satellite clock is in 10-14 level;the clock accuracy is in 10-11 level and clock drift is near 10-13 level.System performance is improved differently in different area.PDOP is improved by 20% to the greatest extent.The new attitude control mode is beneficial to improve the accuracy of orbit determination when satellite is in earth eclipse.
