Abstract

Condition observation and indirect observations are the two basic models for data processing measurement adjustment. This paper applies the transformation of conditional adjustment and indirect adjustment function models to calculate the annexed route and closed error for the GPS network. We can find the relationship between the conditional equation and the coefficient matrix of the error equation, and device the information of annexed route or closed loop in GPS control network by matrix transformation, so that we can obtain the error equation directly and calculate the corresponding closure error. In this paper, we use the program and process the data of the example to verify the method can search the annexed route and the closed loop, and the closing error of GPS control network can satisfy the accuracy requirement.
