摘要

作为保证测试精度和质量的关键环节,GNSS姿态测量仪的动态标定常常因缺乏足够刚性的测试平台和足够精确的标定参考而陷入困境。针对这一问题,提出了一种基于地平座的GNSS姿态测量动态标定方法。介绍了该方法的原理和实现方法,并从底座的适用性、校准精度、校准范围、基线刚度和卫星信号涉及因素等方面详细分析了该方法的可行性和可用性。为了验证和测试该方法,在测量船GPS姿态测量仪上进行了验证性实验,实验结果证明了该方法是一种可行的GNSS姿态测量动态标定方法。

Altazimuth mount based dynamic calibration method for GNSS attitude measurement
As the key process to ensure the test accuracy and quality, the dynamic calibration of the GNSS attitude measuring instrument is often embarrassed by the lack of the rigid enough test platform and an accurate enough calibration reference. To solve the problems, a novel dynamic calibration method for GNSS attitude measurement based on altazimuth mount is put forward in this paper. The principle and implementation of this method are presented, and then the feasibility and usability of the method are analyzed in detail involving the applicability of the mount, calibrating precision, calibrating range, base line rigidity and the satellite signal involved factors. Furthermore, to verify and test the method, a confirmatory experiment is carried out with the survey ship GPS attitude measuring instrument, and the experimental results prove that it is a feasible way to the dynamic calibration for GNSS attitude measurement.
