摘要
测绘生产单位在GPS网的施测中,经常使用品牌、型号不同的GPS接收机联合作业,其结果是不同格式数据的转换、处理方法直接影响到数据处理的精度.作者根据几种常见的GPS数据格式及转换理论,分析了各种转换方法的特点和适用条件,结合实例,采用标准数据格式转换法对不同格式GPS数据联合处理的方法及其精度进行了对比分析;指出了联合处理可提高作业效率、降低生产成本,并应尽可能选择标称精度一致的接收机.实测中,基线长度较长时,需合理配置不同精度GPS数据的权重.
The departments of surveying and mapping usually use different types of GPS receivers in the practice, which the most pivotal problem is the theory of data transformation and processing will directly affects the precision of data processing. In this paper, the author introduces the common formats of the GPS data and transformation theory, and analyses the characteristic of each kind of transformation method and applied conditions. In the end, one example is given to analyze the precision of the jointly processing by the standard data format transformation method, and indicates that the jointly processing can improve the task efficiency and lower the cost, but we should try＇ to choose the consistent receivers of the nominal precision, and the weight of the different GPS data can be rationally allocated when the baselines are long.
