Key factors affecting the work of Realtime tracking GPS tracker:1. The US Department of Defense SA satellite signal interference. (Satellite signals are controlled by the United States, and signal services may occasionally be interrupted)
2. Weather factors. Such as: sunspots, bad weather (reduce signal strength, but does not affect positioning)
3. Electrical electromagnetic interference; under shelters (in buildings, valleys, canyons, tunnels)
4. Heat insulation film, heat insulation paper, and metal component shielding on automobile windshield. (Reduce the signal strength, but does not affect the positioning)
5. The time display is not normal The date and time on the GPS is specially used to display the satellite time. The GPS displays the satellite signal only when it receives the satellite signal. It is abnormal when there is no signal. It is not a commonly used electronic watch and cannot be adjusted and cannot be saved.
GPS positioning principle The satellite positioning system has a total of 24 artificial satellites distributed in 6 working orbits, and each orbit is at an angle of 120 degrees, so that GPS users can receive satellite signals for positioning at any time and place. And it is not affected by the weather (under the influence of terrain or building shading, that is, it is difficult to receive satellite signals indoors or on buses). Realtime tracking GPS tracker is your good choice.
