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度,设计了线位移扰动对准试验、六自由度摇摆台对准试验,评估了动基座对准的水平对准误差及航向对准误差,验证了一种动基座对准方案的有效性。
The inertial navigation systems equipped with ships and aircraft weapons require initial alignment prior to their flight. Due to the actual use environment, the carrier may be disturbed to generate swaying motion, which may cause interference to the alignment of the inertial navigation system. In order to improve the alignment accuracy of inertial navigation system, it is necessary to study the alignment scheme of inertial navigation system under moving base. Experimental verification based on actual system is an important part of technical research and product inspection. In order to effectively evaluate the performance of INS, The accuracy of the system moving base alignment, the design of the line displacement perturbation alignment test, six degrees of freedom swing table alignment test to assess the moving base alignment of the horizontal alignment error and heading alignment error verify a move The effectiveness of the pedestal alignment scheme.
