| 摘 要： | 讨论了基于方位捷联平台的陀螺寻北方案，与传统的捷联式平台不同，方位捷联平台仿真了当地的水平坐标系，并且平台的方位就是载体的方位。通过双位置方法准确计算出载体的方位角，并且抵消了陀螺的常值漂移对寻北精度的影响。分析了平台角误差和转位误差对寻北解算精度的影响。实践证明：此种方法成本低，操作方便，精度较高。

| Abstract: | The scheme for gyroscope north seeker based on azimuth strapdown platform is discussed.Not as general strapdown platform,azimuth strapdown platform simulates horizontal coordinates and it's azimuth is body's azimuth.Azimuth angle is calculated exactly through two-position method and constant drift of gyroscope is cancelled.The effect for accuracy of north-seeker form platform angle error and position transformation error is analyzed.It is proved that this scheme has characteristics of low cost,convenient for operation and higher accuracy. |
