陀螺寻北仪现场校准方法研究
|
摘要
针对现有车载陀螺寻北仪无法现场校准的问题,借鉴陀螺寻北仪实验室校准原理,以及使用的测量标准装置,提出用传递比较测量实现陀螺寻北仪现场校准的新方法。该方法以高精度陀螺经纬仪为传递标准,在外场对平行光管和平面镜进行引北赋值,使其作为陀螺寻北仪现场校准装置的方位角标准,进而对车载陀螺寻北仪进行校准。经实践证明,该方法准确、可行,可供陀螺寻北仪外场测试参考。
The paper is aimed at the matter that vehicle gyro north finder can't be calibrated on the spot. Reference to the principle of gyro north finder found laboratory calibration and use of the measuring device. A new method for field calibration of gyro north finder is presented by means of transfer comparison measurement. The method uses high precision gyro theodolite as transmission standard. In the external field,the parallel light tube and the plane mirror are assigned to the north of the gyro north finder,and then the gyro north finder is calibrated. The method is accurate and feasible,and can be used for reference in the field test of gyro north finder.
