Abstract

The invention is suitable for the technical field of satellite positioning, and provides a differential data broadcasting method and device, a service terminal and a storage medium. The method comprises the steps of receiving a data request of the terminal; matching a base station corresponding to the GGA data of the terminal based on the data request; obtaining corresponding differential data from the matched base station, the differential data being from a base station network, and the base station network comprising a physical base station and a virtual base station; and broadcasting the obtained differential data to the terminal. According to the invention, the capacity expansion of the differential data is realized by integrating the networking modes of the virtual base station and the physical base station, the coverage range of the differential data can be improved, the data requirements of different areas can be met, and the positioning accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of satellite positioning, in particular to a method and device for broadcasting differential data, a service terminal and a storage medium. Background technique [0002] Differential positioning technology is to use the known precise coordinates of the reference station to calculate the distance correction number from the reference station to the satellite, and send this correction number in real time. While observing satellite signals, the user reference station uses the received corrections to correct its positioning results to improve positioning accuracy. The basic principle is that there are common errors related to distance or space in the satellite signal observations between different reference stations. Through differential processing, the common errors in different observations can be eliminated or reduced, thereby obtaining higher-precision positioning results. [0003] The effectiveness of diffe...
