Scientific paper

TC-1 was launched on December 30th 2003 and TC-2 was launched on July 25th 2004. They are two operational satellites with very high orbit eccentricities. The two satellites operate closely with the ESA Cluster-II Spacecraft to form a stereo six-point simultaneous detection in geo-space and to observe and study the mechanism of trigger and development of disturbances in near-Earth space weather. Because of dynamic perturbation, the orbits of TC-1 and TC-2 have been changing since launch date. In this paper the characteristics of orbit evolvement for these two satellites are investigated. Mainly due to solar gravitation and lunar gravitation, the eccentricities of TC-1 and TC-2 change in long period, which result in the changing of perigee. The atmospheric density at 230km altitude is about thousand times larger than it at 700km, which makes different accuracy level for orbit determination and prediction in different time. So the precision of orbit determination and prediction for TC-1 and TC-2 on different stage are analyzed. The plan mode of satellite application can be adjusted according to the satellite perigee to ensure the normal operation of the payload. Some vital change about orbit element of the two satellites in further is also given, the orbit lifetime is assessed based on the evolvement of satellite perigee in
