摘要
为了解决运动载体(如车辆、船舶和飞机等)实时精密水平姿态测量的问题,基于液体自动水平原理,提出了采用“光学编码精密测角+惯性同步复示平台+水平误差检测工具”的水平姿态测量方案,并进行了码头船舶动态原理验证试验。结果表明,测量原理正确、有效、可行,试验设备与惯导设备的水平姿态的差分差值小于等于2.0″[均方根(RMS)值]。该方法可以为运动载体(例如各类军用**发射平台)实时提供高精度的水平姿态信息,并用于运动载体水平结构变形测量、惯导水平精度鉴定等。
Abstract
To measure the level attitude of moving carriers (such as vehicles, ships, aircraft, etc.) in real-time and highly precisely, based on liquid′s automatic level, a method combining high-precision optical angle measurement, inertial synchronous multiplexing platform and level error detection tool is proposed and tested on a docking ship. The test result confirms the correctness, effectiveness and feasibility of this method. The difference D-value between the level attitude measurements of test equipment and inertial equipment is not larger than 2.0″ [root mean square (RMS)]. This method can be used in high-precision measurement of level attitude, measurement of structural deformation and accuracy evaluation of inertial system of moving carriers such as different kinds of military weapon launching platforms.
