Disclosed is a GNSS receiver, including a state monitoring sensor and a processor. The state monitoring sensor is configured to monitor a state of the GNSS receiver, and generate a first triggering signal according to the state of the GNSS receiver. The processor is configured to switch from a resting operating state to a wake-up operating state according to the first triggering signal, and transmit position information about the GNSS receiver to a remote server at a preset rate. Further disclosed is a GNSS device.

A method of automatically switching a mode of receiving differential data for driving test and driver training using a mobile station includes the following steps of: after a mobile station installed on a training vehicle is powered on, using a mode of receiving the differential data by a radio station; if the differential data cannot be received within a preset time period under the mode, switching the radio station to a GPRS mode; if the radio station of the mobile station receives failure information, feeding the information back to a back-end server by the mobile station; informing a technician, by the back-end server, to perform troubleshooting, after the radio station failure is eliminated, feeding information back to the mobile station through the back-end server, and switching the mobile station back to the mode of receiving the differential data by the radio station.
