This application provides a positioning method, equipment, service terminal equipment and storage media, by judging whether there are common grid points within the predetermined range of the central grid point; if so, sending the elevation data of the common grid point and the latitude and longitude data of the central grid point to the benchmark The VRS data is acquired by network computing, and the client performs positioning based on the VRS data; the elevation data of the client in the commonly used grid points is pre-acquired; if not, the elevation data of the grid points obtained through the digital elevation model of the reference network and the earth's gravity field model will be pre-acquired , and the latitude and longitude data of the central grid point are sent to the reference network to obtain VRS data, and the client performs positioning based on the VRS data. It can effectively solve the technical problem that the positioning error caused by the different elevation in the troposphere during the client positioning process is greatly affected.
Description
technical field [0001] The present invention relates to the field of positioning technology, in particular to a positioning method, equipment, service terminal equipment and storage media. Background technique [0002] In the process of positioning by the client using the base station. The error items that affect the terminal positioning solution include satellite orbit error, satellite clock error, tropospheric delay, ionospheric delay, receiver clock error, multipath error, and measurement noise. After the client constructs the carrier phase double-difference observation equation, the satellite clock error and receiver clock error can be eliminated. When the client performs RTK positioning, the positioning error is mainly caused by the difference in elevation in the troposphere, that is, the large positioning error is mainly caused by the difference in elevation of the geographical location of the client user. Contents of the invention [0003] The existing technical p...
