The GPS satellite positioning system is the most commonly used satellite positioning system in the world. Its predecessor is a "Meridian" navigation satellite system developed by the US military. Space satellite navigation GPS positioning system. After more than 20 years of research and experiments, costing 30 billion US dollars, by March 1994, the constellation of 24 GPS satellites with a global coverage rate of 98% had been completed.
The main functions that the GPS satellite positioning system can achieve in civilian use are:
Vehicle tracking function; the actual position of the vehicle can be displayed in real time using GPS and electronic map, 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; it can also realize multi-window , multi-vehicle, multi-screen tracking at the same time. Use this function to track and transport important vehicles and goods.Of course, the quality of some cheap mobile signal jammer products may not be as good as high priced products.
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.
Emergency assistance function; through the GPS positioning and monitoring management system, emergency assistance can be provided to vehicles in danger or accidents. The electronic map of the monitoring station displays the help information and the alarm target, plans the optimal assistance plan, and reminds the on-duty personnel to carry out emergency treatment with alarm sound and light. , and other human services. With the development of society, GPS positioning system has been applied to more and more industries. It plays the role of early supervision and later management, unified distribution, easy management, improving our work efficiency and reducing costs.
Traffic command function; the command center can monitor the running status of vehicles in the area and make reasonable scheduling of the monitored vehicles. The command center can also communicate with the tracked target at any time to implement management.
GPS satellite positioning system has added a lot of convenience to our life, but at the same time, it has also caused some troubles, and these troubles even threaten the personal safety of individuals.
Personal location information is also very easy to be stolen; current location trackers are getting smaller, lighter, and more accurate, which makes it easier for some criminals to steal and monitor the location information of others. condition.
The location information of the vehicle is extremely easy to be obtained by others; it is only necessary to load a specific GPS positioning device on the body to obtain the vehicle location information in real time. This function is widely used in the vehicle transportation industry and the financial loan industry. In fact, this is also certain. To a certain extent, personal privacy is violated.
Therefore, people with awareness of positioning and tracking will have this demand - how to shield or interfere with the GPS satellite positioning system?
