| 摘 要： | GPS载波测姿精度高、启动快,但容易受干扰影响,存在固有的周跳现象.为此提出了一种利用磁阻传感器辅助GPS测姿的新方法,基于载波测量的双差方程,通过基线长度和磁阻航向的双重约束,提高模糊度估计的可靠性和测量的稳定性.实际测试结果表明,该方法有效地剔除了载波姿态测量的异常值,具有应用价值.

| Abstract: | GPS carrier phase based attitude determination has high precision and startup speed,but also has inherent cycle-slip as it is easy to be interfered.A new GPS carrier phase attitude determination method with magneto-resistance sensor integrated is presented,which is based on a double-difference equation and can enhence the robustness of integer ambiguity estimation and the measurement's stability through the double constraints of baseline length and magneto-resistance sensor's heading.Actual measurement resu... |
