摘　　要：采用2014-10-25~2014-11-18的SLR观测数据,对SWARM卫星运动学轨道进行检核。检核结果表明,电离层活动剧烈期间,Swarm-A卫星运动学轨道精度为5.32 cm;Swarm-B卫星运动学轨道精度为4.34 cm;Swarm-C卫星运动学轨道结果为5.27 cm,Swarm-B卫星运动学轨道精度优于Swarm-A和Swarm-C。In this paper, we used the satellite laser ranging(SLR) observations from October 10, 2014 to November 18, 2014, to check the Swarm satellite kinematic orbit. The results show that the orbit accuracy of Swarm-A satellite is 5.32 cm during the high ionosphere activity, the orbit accuracy of Swarm-B satellite is 4.34 cm, and the orbit accuracy of Swarm-C satellite is 5.27 cm. Swarm-B satellite kinematic orbit accuracy is better than Swarm-A and Swarm-C.
