摘要
在处理如GPS控制网的约束平差或以GPS测定导线网的方位角的平差计算中,是否考虑起始数据的误差给平差结果及其精度评定带来的影响是不可忽视的.通过平差模型的推导及数值计算的结果对GPS网中起始数据有误差的平差与精度估算这一问题进行了讨论,提出了一种新方法来实施GPS网的平差,并给出了实施此类计算的建议.
It is not ignorable that there is base datum with less precision to support the network computation and adjustment of a constrained GPS network. With the help of modem geodesy techniques GPS and adjustment theory as well as computational techniques, a new method is put forward to carry out the adjustment of GPS network with less precision to support the computation. Based on the theory and model, a small GPS network is computed in the southwest of China to test the theory and model. Based upon the comparison, suggestions are also made in this paper.
