Abstract
A quick positioning method and a vehicle-mounted system are disclosed. The quick positioning method includes: acquiring position information from an external positioning terminal the same time when the vehicle-mounted system is started, and determining continuously whether position information is available from a local GPS positioning module; and using the position information acquired from the external positioning terminal until position information is available from the local GPS positioning module. By the above method, there would be available position information before the GPS module of the vehicle-mounted system is fully activated, thus effectively enhancing the positioning efficiency of the vehicle-mounted system.
