| Abstract: | In this paper,a model of parameter constraint adjustment is introduced briefly.Compared with traditional adjustment methods,the data processing of the parameter constraint adjustment is more simple and easy to be programmed.Then taking GPS network as an example,the results of classical freedom network,rank deficient network and enclose network adjustment by parameter constraint adjustment are obtained. |

| Keywords: | parameter constraint adjustment three dimension adjustment of GPS network least square estimate free network adjustment |
