Mobile station, differential correction data transmission method, terminal device, and storage medium

Abstract

The present invention discloses a mobile station, a differential correction data transmission method, a terminal device, and a storage medium. A mobile station and a reference station is involved in the present invention; the mobile station comprises a first mobile station and a second mobile station; and a distance between the first mobile station and the reference station is less than the distance between the second mobile station and the reference station. The method comprises the following steps that: communication is established between the first mobile station and the reference station,and the reference station broadcasts differential correction data to the first mobile station; a radio module in the first mobile station forwards the differential correction data to a positioning module and an MPU processor; the MPU processor parses the differential correction data until a specified character is parsed to, so that the differential correction data corresponding to the specified character is saved to a transmission buffer; and the differential correction data of the transmission buffer is transmitted to the radio module, and the radio module transmits the differential correction data to the second mobile station to complete the transmission of the differential correction data. According to the technical scheme of the present invention, multiple mobile stations in the working range can be used to perform data transmission, so that the equipment cost can be reduced, and the efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of satellite navigation surveying and mapping, in particular to a mobile station, a transmission method for differential correction data, a terminal device, and a storage medium. Background technique [0002] In the process of outdoor RTK surveying, it is usually necessary to set up a base station, and the mobile station can realize real-time high-precision positioning of the carrier phase by receiving the differential correction data from the base station. The base station usually uses an external data transmission station to broadcast the differential correction data in real time. But in actual work, due to the limited power of the data transmission station, the transmission distance is also limited, especially in some complex terrain environments, the mobile station usually cannot receive the differential correction data broadcast by the base station data transmission station. At present, the main techni...

But in actual work, due to the limited power of the digital transmission station, the transmission distance is also limited, especially in some environments with complex terrain, the mobile station usually cannot receive the differential correction data broadcast by the digital transmission station of the base station

At present, the main technical means to solve this problem is to set up a relay station for data transfer, but this solution needs to be equipped with a large battery and a data transmission station in the relay area, and also requires a surveyor on duty to prevent loss

This scheme brings a greater burden to outdoor operations
