In order to improve the user experience, a GNSS (Global Navigation Satellite System) receiver for mapping generally has a self-checking function, and the automatic checking of the working state of each hardware module inside a host is realized by directly operating on the host, so as to realize the rapid positioning of a fault. The module requiring self-checking in the GNSS receiver generally includes a GNSS main board module, a radio station module, and a cellular network module. The general self-checking scheme is to sequentially power on each module, then perform some initialization configuration on each module through a serial port, and if the configuration is successful, the module is considered to work normally, thereby informing a user that the self-checking is successful, otherwise, the self-checking is failed.
However, for the radio module, initialization configuration is performed only through a serial port, and it is an imprecise self-checking method to determine that the module is in a normal state according to success of the initialization configuration, because two GNSS receivers need to communicate with each other by using a built-in radio module in a conventional RTK (Real-time kinematic) operation, only the radio module of one GNSS receiver is confirmed to be able to work normally, and there is no significance for RTK operation. However, the RTK operation is an important application direction of the GNSS receivers, and therefore, whether the built-in radio modules in the two GNSS receivers can communicate normally is a crucial indicator.
In order to implement RTK operations, after a self-check scheme is completed, the user needs to perform different manual settings on the two GNSS receivers respectively to verify whether the radio station modules are normal or not when the working state of the radio station modules is comprehensively evaluated.

In this embodiment, the reference station and the mobile station are both GNSS receivers, and in order to ensure the accuracy of the detection result, the reference station and the mobile station are disposed at the same position.
In this embodiment, the number of the reference stations is one, and the radio station module corresponding to the reference station belongs to a broadcast data mode. The number of mobile stations performing mutual self-check with the reference station may be 1, or may be multiple, and the reference station only needs to be capable of realizing information transmission with the mobile stations, and is not limited herein.
In this embodiment, the radio module is built in the reference station and the mobile station, and the processor of the reference station and the processor of the mobile station are respectively connected with the corresponding radio module through serial interfaces, in other embodiments, the radio module may be externally installed on the reference station and the mobile station, or the radio module may be connected with the processor of the reference station and the processor of the mobile station through parallel interfaces, wireless transmission, and the like to transmit information, which is not limited herein.
