Beschreibung
Zusammenfassung:	Disclosed is a PC5 short-range communication roadside device that provides a high-precision positioning service, comprising a main processing unit, a PC5 short-range communication unit, a differential positioning edge calculation unit, a GNSS receiver unit and a 5G communication unit. The PC5 short-range communication unit receives GNSS information sent by a vehicle-mounted terminal, and the GNSS information passes through preprocessing by the main processing unit and is then sent to the differential positioning edge calculation unit; the differential positioning edge calculation unit combines GNSS information sent by the GNSS receiver unit of the differential positioning edge calculation unit and longitude and latitude information calibrated by the differential positioning edge calculation unit to carry out a differential calculation, so as to obtain high-precision GNSS positioning information; and then the high-precision GNSS positioning information passes through processing by the main processing unit and
