摘　　要：全球导航卫星系统(GNSS)接收机在时间校准、位置确定、轨道服务等方面发挥了较为重要的作用。文章以亚太6E卫星全轨道周期高低轨融合GNSS接收机为研究对象,针对飞行特点开展了系统方案设计,对覆盖低轨道、中轨道、高轨道的GNSS接收机设计及实现进行了阐述,结合亚太6E卫星实际飞行数据,对全轨道导航性能开展了数据分析与评估。结果表明:本次在轨飞行验证了GNSS接收机用于全轨道周期的可行性,精度满足全轨道周期轨道修正,可为后续化学和电混合推进、长周期转移轨道卫星的全轨道导航定位提供设计及应用参考。Satellite GNSS receivers have played an important role in time calibration,positioning and orbit determination.The high-and-low-orbit-compatible GNSS receiver of APSTAR-6E satellite as the research object is taken in this paper,based on the mission characteristics,then it elaborates on the design and implementation of GNSS receiver used in the low orbit,medium orbit,and high orbit.Finally,it conducts data analysis and evaluation of the full orbit navigation performance based on actual flight data of APSTAR-6E satellite.The results show that the orbit-compatible GNSS receiver is proved to be feasible,and the measurement accuracy of GNSS receiver meets the mission requirement of APSTAR-6E satellite.It can provide a reference for the full orbit navigation positioning system of chemical-and-electric hybrid propulsion and long-period transfer orbit satellites.
