　　What is the reason for GPS locator interference?

　　Answer: Firstly, you need to understand how the GPS system operates; The GPS positioning system has a total of 24 artificial satellites operating on 6 working orbits, with each orbit forming a 120 degree angle with each other, allowing GPS users to receive satellite signals for positioning at any time and place.

　　2. Due to being in outer space, signals generally run at the shortest distance between two points - a straight line. Therefore, GPS locators are affected by weather, terrain, buildings, and it is also difficult to receive GPS satellite signals indoors and on buses.

　　3. Weather factors. Bad weather such as rainstorm will seriously affect the satellite signal, but will not affect the positioning function.

　　4. Electromagnetic interference. Like subway tunnels.

　　5. GPS jammer or GPS blocker.

　　6. Windshields, metal covers, insulation paper, and so on for cars. (Will reduce satellite reception signal, but does not affect positioning function)
