| 摘 要： | 为解决船用捷联惯导系统传递对准仿真中载体机动方式与实际差别较大的问题,提出了基于舰船空间运动的传递对准精度考核的仿真验证系统,提高载体机动方式仿真逼真度。仿真验证系统通过舰船空间运动建模,提供接近真实运动环境的空间运动参数;通过设计空间变换算法,实现了空间运动参数与主惯导惯性器件模拟输入的转化;通过杆臂及挠曲变形计算,实现了子惯导惯性器件模拟输入的转化;文中给出了各模块的算法及解算流程。速度+姿态传递对准算法仿真验证结果为10 s内水平失准角精度优于0.02;方位失准角精度优于0.05。仿真验证试验结果表明了该方案的可行性和实用性,该方案为其他领域的传递对准方案分析及验证提供了有效的参考依据。

| Abstract: | A transfer alignment simulation and verification scheme based on the ship motion is proposed to improve the simulation fidelity for shipborne inertial navigation system.Compared with conventional schemes,the new scheme can bring motion parameters that are more close to actual motion environment by using the 6-degree of freedom ship motion.The designed space transform algorithm realizes the transform between space motion parameters and analogy input of main inertial navigation devices.The transform of analog... |
