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.
