| Abstract: | The construction of smart cities requires accurate coordinates of the city's basic points, which are often statically solved by joint measurement with the local continuous operation reference station system (CORS). The LGO software of Leica is usually used for static calculation, and the LGO software cannot identify the antenna type of the the South Group’s GNSS receiver. When using LGO to calculate the southern static observation data, the antenna will be undefined, which will cause the antenna height error, affect the accuracy of baseline calculation and network adjustment, and result in elevation error. The reason for the antenna undefined problem is analyzed, and the influence of antenna height error on the GNSS static positioning accuracy is derived from the model. On this basis, suggestions and ideas for correctly obtaining the antenna height are put forward, which provides a reference for solving similar problems. |
