Research on the INS Transfer Alignment Technology and Sea Experiment Verification

摘要:

设计了抖动偏频激光陀螺捷联惯导系统的动基座传递对准方案,并进行了仿真计算及海上试验验证。激光陀螺捷联惯导系统采用该传递对准方案在试验船上完成了数十次海上传递对准试验,结果表明,该传递对准方案具有如下优点:在传递对准过程中,不专门要求载体作加速或S型机动运动；抗载体扰动运动的能力强；对准精度高。

Abstract:

In this paper, the single frequency dithering strap-down INS transfer alignment scheme was designed, and the simulation sea experiment verification were done. The INS employed the transfer alignment algorithm to go through more than 10 times transfer alignment on the sea and the experiment result indicated several advantages of the transfer alignment scheme, such as that no requirement for S mode or acceleration for the body equipped with INS during transfer alignment, good ability of anti body turbulence and high accuracy of alignment.
