摘　　要：针对地面固定测控站以及车载机动测控站在作战条件下的抗毁性、机动性和灵活性不足的问题,研究了基于便携式终端的卫星应急测控技术。根据便携式终端的特点设计了低密度弹性遥测体制和多测速实时轨道测量体制,不仅能够充分发挥便携式终端灵活性、隐蔽性的优势,而且能够回避其链路传输能力和数据处理能力的弱点。理论分析与仿真结果显示,当终端布站半径达400 km,测速误差控制在0.1 m/s以内时,对低轨卫星的定轨精度可达米级,满足战时卫星管控和信息支援的需求;且测控终端之间的基线越长、测速误差越小,定轨精度越高。In order to solve the problems of lacks of survivability, motility and flexibility in ground TT＆C stationand vehicle-mounted TT＆C station under condition of war, satellite emergency TT＆C technology for portableterminal is studied. A low density elastic telemetry system and a real-time orbit determination system based onmulti-velocity measuring are designed considering the characteristics of the portable terminal, which can not onlygive full play to the advantages of mobility and concealment of the portable terminal, but also avoid theweaknesses of link transmission and data processing ability. The theoretical analysis and simulation results showthat when the terminal station distribution radius is 400 km and the velocity error is controlled within 0. 1 m/s,the LEO satellite orbit determination precision can reach meter level, which meets the needs of satellite controland information support in wartime. Furthermore, the longer baseline between the terminals and the smaller thevelocity error are, the higher the accuracy of the orbit determination is.
