论文对基于GNSS的飞行器姿态测量进行研究。考虑姿态测量系统基线长度固定的特点,建立了单基线测量的载波相位差分姿态方程。在解算姿态方程时,为克服可能出现的载波相位观测值异常情况,提出了基于抗差卡尔曼滤波的飞行器姿态解算算法。仿真结果表明,该算法具有比最小二乘法更高的姿态解算精度和稳定性。
Papers on GNSS-based aircraft attitude measurement research. Considering the characteristics of the baseline length of the attitude measurement system being fixed, a single baseline measurement of the carrier phase difference attitude equation is established. In solving the attitude equation, in order to overcome the possible anomaly of the observed phase of the carrier phase, a pose algorithm based on the robust Kalman filter is proposed. The simulation results show that the proposed algorithm has higher accuracy and stability than the least square method.
