惯导系统动基座对准精度试验评估

舰船、飞机武器装备出航前,其装备的惯性导航系统需要进行初始对准,由于实际使用环境的影响,载体可能受到扰动而产生摇摆运动,从而对惯导系统的对准造成干扰.为了提高惯导系统的对准导航精度,需要研究惯导系统在动基座条件下的对准技术方案,基于实际系统的试验验证是技术研究和产品检验交付的重要环节,为了有效评估惯导系统动基座对准的精...

The Test Evaluation of INS Alignment Precision on Moving Base

INS （Inertial Navigation System） has to be aligned properly before the aircraft or warship turn into navigation state. Because of the actual application environment disturbing effect, the vehicle maybe sway randomly when the INS is aligning. So the INS alignment process is going to be badly disturbed. In order to improve the INS alignment precision, the technical scheme of INS alignment on moving base should be studied seriously. The real system test validation is an important process for technology research and product inspection. For effective evaluation the precision of INS alignment on dynamic base, a linear displacement test method and a 6-DOF Stewart platform test method were presented in this paper. The heading direction error and horizontal line error of INS alignment on moving base were evaluated effectively by means of these methods.
