| 摘 要： | 分析了惯导／双星定位组合的可行性；针对惯导／双星定位组合导航在飞行器上应用存在的有关问题进行了讨论，提出了可能的对策。通过不同方案的比较分析，给出了较为实用的惯导／双星定位组合导航系统设计方案，并对组合的时机和组合导航的精度进行了仿真计算和结果分析。结果表明，采用按精度要求进行惯导／双星定位位置组合，可以在某种程度上弥补双星定位导航系统为有源系统的缺点，并具有较高的精度。

| Abstract: | This paper focuses on the feasibility analysis, scheme demonstration and performance evaluation of INS/Twin-star integrated navigation system. The necessity and realization probability of the INS/Twin-star integrated navigation system are analyzed and the problems existed in the INS/Twin-star integrated navigation system are discussed, and the possible countermeasures to settle these problems are put forward. Different integration modes are analyzed and compared. A feasible integration scheme, which uses the position information from the Twin-star user transceiver to estimate the errors of INS by Kalman filtering, is presented. Simulation works, under different situations, are carried out. The simulation results indicate that the integration of Twin-star satellite navigation system with INS can not only overcome the disadvantages of the Twin-star satellite navigation system but also calibrate the errors of INS. The research works have great value on the development of INS/Twin-star integrated navigation system. |
