The main functions that GPS satellite positioning system can achieve in civilian use are:
Call traffic command function; the command center can monitor the running status of vehicles in the area and reasonably dispatch the monitored vehicles. The command center can also communicate with the tracked target at any time to implement management.gps jammer can be detected and located by mobile direction finding systems. Spectral analysis to determine the duration and signal type of interference can also be used to indicate whether the interference is accidental or intentional.
Route navigation function; providing travel route planning is an important auxiliary function of the car navigation system, which includes automatic route planning and manual route design. The automatic route planning is that the driver determines the starting point and destination, and the computer software automatically designs the optimal driving route according to the requirements, including the calculation of the fastest route, the easiest route, and the route with the least number of highway sections. In manual route design, the driver designs the starting point, ending point and waypoint according to his own destination, and automatically establishes a route library. After the route planning is completed, the display can display the designed route on the electronic map, and at the same time display the vehicle running path and running method.
Vehicle tracking function; the actual position of the vehicle can be displayed in real time using GPS and electronic maps, and can be zoomed in, zoomed out, restored, and changed at will; it can move with the target to keep the target on the screen; Vehicle, multi-screen simultaneous tracking. Use this function to track and transport important vehicles and goods.
Information query function: Provide users with databases of major objects, such as tourist attractions, hotels, hospitals, etc., users can display their positions on the electronic map. At the same time, the monitoring center can use the monitoring console to query the location of any target in the area, and the vehicle information will be displayed on the electronic map of the control center in digital form.
As 5G systems move into frequencies used by GPS, interference is likely to become more widespread. The key point is that civilian signal jammers are completely open, they are not encrypted, they are not authenticated, they are completely open and completely immune to spoofing attacks.
