摘要: 针对地/地导弹发射车、指挥车、侦察车等陆地战车对车载定位/定向系统越来越高的要求,提出了一种利用光电探测系统测量3个已知标志点与地面车辆之间的角度信息来精确确定地面车辆的位置和航向的方法.仿真结果表明:只需依次对3个已知标志点进行1次光电测角,就可以精确确定地面车辆的位置和航向,并且东向和北向定位误差小于0.5m,方位误差小于20″(1σ).这种方法简单、快速,定位定向精度高,且能同时服务于同一场地的多辆地面车,具有重要的实用价值.

Abstract: For the increasingly higher requirements of land navigation systems for the modern military vehicles, such as mobile silos, command stations, scout vehicles and so on, a new approach of position and azimuth determination for land vehicles was presented utilizing the angle information to three known landmarks measured by the electro-optical detection system which was mounted on the roof of the vehicle. Computer simulation results indicate that the position and azimuth of land vehicles can be accurately determined only based on once measurement information of each landmark by the electro-optical detection system, both estimation errors of vehicle position along east- and north-axis are mostly less than 0.5 meters, and the azimuth angle error can reach 20 arcsec (1σ). Besides high accuracy, the approach proposed is simple and quick, and it is capable of serving several land vehicles at the same time, hence it is of great value in practice.
