动态对动态差分相对定位方法建模与测试

摘要

揭示了传统的GNSS差分处理技术在基准站移动时所面临的问题，从差分实现的原理上首次对该问题进行了理论解释。针对这一问题建立了动态对动态差分相对定位模型，提出了测试方案并进行相应的试验验证，结果表明：所提动态对动态差分相对定位方法精度达到10cm量级，能够满足高精度动态对动态测量需求。%Problems appeared in conventional differential GNSS working with a moving reference are proposed and the reasons are explained from the principle of difference GNSS for the first time .The model for relative positioning to a moving reference is built and the test method is proposed .The experimental results show that the accuracy of the proposed method can reach 10cm level ,which can satisfy the requirements for precise relative positioning to a moving reference .
