GPS satellite positioning and navigation functions

According to the prediction of authoritative organizations, the domestic market of car GPS navigation and positioning products will reach 10 billion yuan in 2008. The addition of GPS satellite positioning and navigation functions to vehicle DVRs will be the main trend in the future.
The vehicle-mounted hard disk recorder adds GPS positioning module to know the latitude, longitude, altitude, speed and direction of the vehicle in real time. The GPS satellite positioning function of the vehicle-mounted hard disk recorder needs to be combined with wireless transmission to provide information about the vehicle position of the vehicle dispatching system. If the car DVR can perform GPS navigation through the local display LCD screen, it can increase the added value of the car DVR product.
