Positioning calibration method, device and equipment of vehicle-mounted 5G terminal and storage medium

The invention relates to the technical field of vehicle-mounted positioning, in particular to a positioning calibration method and device for a vehicle-mounted 5G terminal, equipment and a storage medium. When it is determined that the vehicle-mounted 5G terminal is in the complex environment, an uplink RTT test signal is sent to the base station, a first timestamp for sending the uplink RTT test signal is recorded, and the uplink RTT test signal comprises an IMEI identifier of the vehicle-mounted 5G terminal; a downlink RTT test signal fed back by the base station is received, a second timestamp for receiving the downlink RTT test signal is recorded, and the downlink RTT test signal comprises a third timestamp for the base station to receive the uplink RTT test signal and a fourth timestamp for the base station to send the downlink RTT test signal; determining a target error duration between the vehicle-mounted 5G terminal and the base station according to the first timestamp, the second timestamp, the third
