Design of New Marine SINS Digital Simulator

摘要:

以舰船的运动特性为依据,设计了一种新的船用捷联惯导系统数字仿真器；用VC++编程语言设计舰船运动轨迹；建立陀螺仪、加速度计的误差模型；用惯导系统姿态更新、位置更新、速度更新解算的结果与航迹点参数(真值)比较,得到惯导系统误差；应用表明,该仿真器能够灵活地模拟出舰船在不同的运动状态下船用捷联惯导系统的各种导航参数,为研究舰载条件下的捷联惯导系统传递对准技术提供了可靠的试验数据。

Abstract:

Based on the characteristic of ship’s trajectory, the article designed a new ship SINS’ digital simulator. Used VC++ programming language to design the trajectory of ship, then compared the results of renewing INS’ attitude, position and velocity, with the track points(the truth-value).And we can have the error of the inertial navigation system. The results show that this method can simulate a SINS, which can reach average accuracy requirements. This digital simulator can provide credible data for research of aircraft carrier SINS’ transfer alignment technology on ship-board. 
