| Abstract: | The kinematic orbit determination of LEO satellite software named GNSS_LEO_KPP is developed,and the observation data of GRACE_A and GRACE_B satellites in 7 days from DOY220/2011 to DOY226 / 2011 are calculated.Compared with the JPL precise orbits,the accuracy of final kinematic orbit can reach 10—20 cm.The results show that: the priori orbit quality has a certain level of impact on the final kinematic orbit quality,so we could use the iterative loop kinematic orbit as a prior orbit,and the final kinematic orbit accuracy can be maintained in decimeter or sub-centimeter level. |
| Keywords: | GNSS navigation constellation kinematic orbit determination LEO priori orbit |
