摘要
根据当前轨检仪检定规程中尚不明确的部分,提出了更加合理的检测轨检仪实际测量精度的方法。介绍了测量检测场地轨道基础数据的方法,以及如何对轨检仪轨道测量实测数据进行精度分析。最后以某惯导型轨检仪的实际检测为例,对比了本文方法与检定规程方法的差异,验证了本文方法的正确性,并对所检测轨检仪的实际轨道测量精度进行了统计分析,可为惯导型轨检仪的检测方法和工程应用提供参考依据。
According to the unclear part of the current standard of the calibration of the track detector,we propose a more reasonable method for detecting the actual measurement accuracy of the track detector and is introduced the method of measuring the basic data of the track in test site. Finally,taking the actual detection of an inertial navigation track detector as an example,the difference between this method and the normal method is analyzed,and the correctness of the method is verified. The actual measurement accuracy of the detected track detector is also statistically analyzed. It provides a reference for the detection method and engineering application of the inertial navigation track detector.
