It can provide accurate geographic location, vehicle speed, and time information anywhere in the world and in near-Earth space. Since its inception, GPS has attracted numerous users with its high-precision, all-weather, global coverage, and convenience and flexibility. GPS is not only the guardian angel of automobiles, but also a wise star in the management of the logistics industry.
