Abstract

We describe a method, which allows analyzing the influence of the errors induced by gyroscopic channel of strapdown inertial navigation system (strapdown INS) on the errors of INS autonomous mode. The method is implemented using a computer simulator of the SINS. A general approach to the procedure for modeling errors in a computer simulator with a zero test is developed. Simulation made it possible to identify the inertial errors of the INS dead reckoning in cases of various types of aircraft trajectories when digital data processing is applied in the gyroscopic channels of the laser angular rate sensors.

自主模式下捷联惯导陀螺通道误差影响分析方法

摘要

我们描述了一种方法，该方法允许分析捷联惯导系统（捷联 INS）的陀螺通道引起的误差对 INS 自主模式误差的影响。该方法是使用 SINS 的计算机模拟器实现的。开发了在具有零测试的计算机模拟器中对错误进行建模的过程的一般方法。在激光角速率传感器的陀螺通道中应用数字数据处理时，仿真使得在各种类型的飞机轨迹情况下识别惯性导航系统的惯性误差成为可能。
