摘要:

针对惯性导航系统极区性能试验难以实地开展的问题, 研究了一种模拟测试的方法, 并基于横向坐标系编排给出了以组合导航系统作为测量基准的惯导模拟测试方案。首先分析了模拟测试技术研究的必要性, 然后根据轨迹形变最小原则详细推导了基于横向坐标系编排的极区模拟测试转换公式, 之后针对测试中采用不同基准的情况, 提出了相应的惯性测量单元(inertial measurement unit, IMU)转换算法, 并提出以惯性导航系统/全球导航卫星系统(inertial navigation system/global navigation satellite system, INS/GNSS)为参照基准的一种具体测试方案, 最终完成了仿真实验, 验证了模拟测试理论的正确性。结果表明, 在基准误差不计的情形下,试验导航参数误差与惯导实地横向编排解算误差相当。初步验证了所提方法替代极区实地试验进行精度性能评估的可行性, 为后续极区模拟测试评估研究奠了定理论基础。

Abstract:

Aiming at the problem that it is difficult to carry out the polar performance test of inertial navigation system in the field, a simulation test method is studied, and an inertial navigation simulation test scheme with integrated navigation system as the measurement benchmark is given based on the arrangement of transverse coordinate system. Firstly, the necessity of simulation test technology research is analyzed, and then according to the principle of minimum trajectory deformation, the polar simulation test conversion formula based on transverse coordinate system is deduced in detail. Then, according to the situation that different benchmarks are used in the test, the corresponding inertial measurement unit (IMU) conversion algorithm is proposed, and a specific test scheme based on inertial navigation system/global navigation satellite system (INS/GNSS) is proposed, Finally, the simulation experiment is completed to verify the correctness of the simulation test theory. The results show that when the reference error is ignored, the error of test navigation parameters is equivalent to that of inertial navigation field transverse arrangement solution. The feasibility of the proposed method to replace the polar field test for accuracy performance evaluation is preliminarily verified, which lays a theoretical foundation for the follow-up polar simulation test and evaluation research.
