Embodiment 1
[0038] Such as figure 1 As shown, the present invention provides a mobile station, which at least includes a radio module, a CPLD (Complex Programmable Logic Device, Complex Programmable Logic Device), a positioning module and an MPU processor, and the radio module receives information broadcast by a reference station in real time. The differential correction data, through the CPLD to carry out the distribution of the differential correction data, forwarded to the positioning module and the MPU processor; the MPU processor parses the differential correction data, and passes the resolved differential correction data through the CPLD forwarded to the radio module, and then transmitted to other devices by the radio module.
[0039] Through the two-way connection between the radio module, the MPU processor and the CPLD, the differential correction data is split, one path is used for RTK calculation in the positioning module, and the other path is sent to the MPU processor for anal...
Embodiment 2
[0041] The present invention provides a transmission method of differential correction data, which is applied to mobile stations for outdoor measurement, including at least a first mobile station and a second mobile station, and the distance between the first mobile station and the reference station is smaller than that of the second mobile station The distance between the station and the base station; including the following steps:
[0042] The first mobile station receives the differential correction data broadcast by the reference station in real time;
[0043] The radio module inside the first mobile station forwards the differential correction data to the positioning module and the MPU processor;
[0044] The MPU processor parses the differential correction data until the specified character is resolved, then saves the differential correction data corresponding to the specified character to the sending buffer;
[0045] The differential correction data in the sending buff...
Embodiment 3
[0058] Such as image 3 The illustrated electronic device includes a memory, a processor, and a program stored in the memory. The program is configured to be executed by the processor. When the processor executes the program, the steps of the above data backup method are realized.
