Construction review and optimization design of Shandong gravity network

In the paper, we introduce the development history and current situation of gravity survey network in Shandong Province, including the construction of gravity survey network in the 13th five-year plan of Shandong Province. Then we think it is necessary to optimize Shandong gravity network, especially to increase gravity survey points in the western region of Shandong Province. At present, the scope of Shandong gravity network is expanded from the southern Shandong and the Jiaodong region networks to the western Shandong network. It is also connected with Henan and Hebei networks to achieve full coverage in Shandong and its neighboring provinces. The design of Shandong gravity network such as partition and measurement route is elaborated, and the characteristics and accuracy requirements of the network type are explained. Finally, the monitoring capability of Shandong gravity network is evaluated.
