框架控制网(CP0)作为高速铁路平面控制测量的起算基准,采用适合长基线解算的高精度专用软件,利用精密星历,按照多基线模式进行解算。结合相关测量数据处理经验及通用GPS网平差软件研发,对框架控制网GPS基线网平差方法进行研究分析,在此基础上就网平差观测值提取及随机模型重构、框架基准转换及基线网平差等提出见解,提高了基线解算的可靠性和精度。

Combining with the real data processing experiences and the development of the general GPS network adjustment software, we analyzed and summarized the adjustment method for GPS framework control network baseline network in this paper. On this basis, we put forward some principles and methods of the adjustment observation extraction, random model reconstruction and the datum transformation. This study can improve the reliability and precision of baseline solution, and provide some references for personnel engaged in related work.
