| Abstract: | The deformation monitoring network adjustment method with considering the prior information are the paper researched. The functional model is given and the optimum solution formulas are deduced. Whether the prior information is considered or not, the parameter estimation formulas are the same. The estimation accuracy and applicable condition analysis were also carried out. The study reveals the relationships among prior accuracy, the quality of virtual observations and the adjustment accuracy. The calculation example of deformation monitoring network adjustment shows that considering the prior information can improve the accuracy of the parameter estimation |
| Keywords: | parameter estimation prior information deformation monitoring Bayes estimation surveying adjustment |
