摘要： 倾斜同步轨道(IGSO)卫星交叉点位置在各种轨道摄动因素和入轨偏差的共同影响下,其交叉点位置会在赤道上发生漂移,这种漂移将导致服务区域的漂移,从而影响系统的性能,因此IGSO卫星需要进行定期的交叉点位置保持来保证服务的稳定。对IGSO卫星交叉点位置的演化和保持问题进行了深入的研究,首先,讨论了IGSO卫星交叉点位置的演化规律,给出了在地球非球形引力、日月引力摄动以及卫星入轨偏差作用下的交叉点位置的演化公式,并分析了公式的精度;接着,在对交叉点位置演化规律的分析基础上,进一步讨论了IGSO卫星交叉点位置保持策略。

Abstract: The shift of the cross node of IGSO is a significant reason of changing the service region of IGSO satellite and degrading the performance of system,so the node location keeping of IGSO satellite is required.The IGSO cross node location evolution and keeping were investigated.The formula and rule of cross point evolution acted by earth gravity perturbation,third-body perturbation and bias of working orbit,were given.The maintenance strategy of IGSO node location was described.
