摘要
舰载武器发射或舰载武器惯导系统对准需要舰载惯导系统MINS的信息辅助,不同的安装位置使得它们之间存在较大的杆臂效应,在对杆臂效应补偿中需要三维杆臂尺寸参数,由于加工误差、安装误差及船体变形,使武器战位的实际杆臂参数偏离图纸计算值。通常舰载惯导舱室与甲板武器战位之间不能通视直接测量难度大。为提高杆臂效应补偿精度,提出了基于舰载惯导MINS及差分GPS辅助的测量方案。通过速度信息观测采用马尔科夫递推滤波器估计杆臂参数,仿真结果表明通过10min的测量可达到0.1m估计精度量级。
It is necessary to use the MINS（Marine Inertial Navigation System） information during shipboard weapon＇s emission or the weapon＇s INS alignment process. The lever arm effect between the MINS and weapon＇s installation site is remarkable due to the difference installation position at the warship. In order to compensate lever arm effect, it is necessary for us to know the three dimension size. Because of the manufacture error, fixing error and flux deformation, the actual size parameters will differ from the designed. In generally it is invisible between the MINS cabin and weapon＇s installation site at deck, so it is difficult to measure the dimension directly. This paper brings forward an effective measurement method based on MINS and DGPS velocity observation. The actual size parameters can be estimated by means of Markov recursive filter. The simulation results show that an accuracy level of 0. 1m can be reached in almost 10 minutes measuring.
