Automobile GPS navigation system consists of three parts, one is the ground control part, which consists of main control station, ground antenna, random measuring station and communication auxiliary system. The second is the space part, which consists of 24 satellites distributed in six orbital planes. The third part is user equipment, which consists of GPS receiver and satellite antenna.
The latest development trend of Mercedes-Benz glc260 car navigation system is to use Bluetooth wireless technology to receive signals transmitted by car GPS. In this way, the vehicle-mounted system only needs to receive and process satellite signals, and the display device is responsible for the storage of maps and the superposition of positions. So, if you already have a PDA, you just need to buy a signal receiver and drawing software. PDA can be used for many purposes. In fact, many mobile phones already have GPS function. If you add the overlay function of the map, you can turn it into a mobile navigation system.
