摘　　要：针对船用指北方位平台式惯导模拟器的需要,设计了一种贴合于舰船实际情况的轨迹发生器。根据舰船常见的运动状态给出了轨迹发生器的解析式方程,以及需要输入软件系统的运动参量,并在实验部分对设计的轨迹发生器进行了仿真实验。通过将轨迹发生器生成轨迹以及惯导在轨迹发生器生成的IMU参数下,自主、组合工作模式生成的轨迹进行比较,证明了算法的有效性。本文研究结果可为下一步船用指北平台式惯导模拟器的设计提供软件支持。In order to meet the needs of the platform inertial navigation simulator in the North position,a trajectory generator is designed,which is suitable for the actual situation of the ship.According to the common motion state of the ship,the analytic equation of the trajectory generator is given,and the motion parameters of the software system need to be input.In the experimental part,the trajectory generator is simulated.By comparing the generated trajectory of the trajectory generator,the inertial navigation system generates trajectory under the IMU parameters generated by the trajectory generator and in the independent and combined mode,which proves the effectiveness of the algorithm.The research results of this paper can provide software support for the next step of the design of the platform inertial navigation simulator.
