Brief analysis of GPS anti-theft equipment function

Vehicle global satellite positioning query
  Users can use cell phones to dial the phone, query the vehicle's geographic location information (longitude, latitude, direction, altitude, vehicle running speed, time)
  By dialing the SIM card number of the GPS system and hanging up the phone after hearing the ringing more than once, users can receive the positioning information of the vehicle; by sending short messages to the locator, users can also receive the returned positioning information of the vehicle. During the inquiry process, if the vehicle is in a region where GPS signal cannot cover, such as underground parking lot, the locator will return the prompt of no GPS signal, and at the same time return the last received GPS positioning information.
Remote Control
