| Abstract: | In the deformation monitoring network design of GPS,the sensitivity is a very important quality indicators,it reflects the minimum value of deformation and its direction monitoring which can be detected.The ultimate purpose of Optimal design of GPS deformation monitoring control network is to choose reasonable baseline connection mode which can be satisfy the sensitivity of the need to control network and the least charge.We propose the rationale of optimal design of GPS control network based on the sensibility and prove its feasibility by an example.We discuss the affect of independent baseline number to outcomes,and design a high slope control network to show the effect of optimal design of control network to the quality of control network. |
