Research on transfer alignment simulation and verification system for shipborne weapon inertial navigation system

针对传统船用惯导系统采用理想运动状态对传递对准方案进行仿真验证的问题,提出了引入舰船空间运动模型的传递对准仿真验证方法。通过舰船空间运动模型提供接近真实运动环境的空间运动参数,并实现了空间运动信息至惯性敏感信息的正确转换,给出了各模块的空间变换算法转换流程。"速度+姿态"子惯导传递对准模块的仿真精度优于0.05°,证明了仿真验证系统变换算法的正确性。该研究设计为开展其它领域的传递对准仿真验证提供了有效的参考依据。

Aiming at the problem that the traditional shipborne inertial navigation system adopts the ideal motion state to verify the transfer alignment scheme, a new verification method based on ship space motion is proposed. The space motion model can provide the ship motion information similar to real motion environment. The transformation relationship between the space motion and the inertial sensing information is realized correctly, and the transformation flow of space transform algorithm of each module is given. The result of the simulation precision of velocity plus attitude algorithm excel O. 05~, verifies the correctness of the transformation algorithm. The research achievement provides an effective reference for the simulation and verification of transfer alignment in other research fields.
