【Abstract】 Several theoretical questions are discussed about integral adjustment of Guangxi C_order GPS control network,including principle and method of designing and dividing C_order GPS control network, the scheme of detecting of outliers of baselines of GPS control sub_nets and unconstrain adjustment. A scheme is put forward proceeding neighbor subnets local integrated adjustment, using Helmert variance component estimation method to determine baselines weights to detect outliers of GPS baselines of different subnets. Unconstraint adjustment is made to analyse and test Guangxi regional C_order GPS inside precision. Series of adjustment can be used to obtain gradually integrated result of Guangxi regional C_order GPS network. It can not only improve integral precision of Guangxi regional C order GPS network,and also satisfy present economic construction requirement.更多还原
