针对目前仍有较多通航飞机无法获取姿态数据这一现状,根据通航飞机的运动规律,提出了一种基于MEMS惯性传感器的姿态数据采集方案,选择合适的传感器以及姿态解算算法。硬件设计完成后,利用全动模拟机进行实验,将采集的数据利用MATLAB进行仿真,与模拟机真实数据进行对比,误差在接受范围内,验证了系统的可行性。
Aiming at the current situation that more navigation aircraft can not obtain attitude data, a attitude data acquisition scheme based on MEMS inertial sensors is proposed according to the movement law of navigation aircraft. Appropriate sensors and attitude solving algorithms are selected. After the completion of the hardware design, the experiment was carried out by using full-motion simulator. The collected data were simulated by MATLAB and compared with the real data of the simulator. The error was within the acceptable range, which verified the feasibility of the system.
