What are the general factors that affect the GPS locator to receive satellite signals?

1, satellite signal interference, satellite signal is controlled by American GPS satellite, and signal service may be interrupted occasionally;

2. Weather factors. Such as: sunspots, bad weather (reducing signal intensity, but not affecting positioning);

3. Electromagnetic interference; In a hidden place (in buildings, valleys, canyons, tunnels)

4. Thermal insulation film, thermal insulation paper, shielding of metal parts, etc. On the windshield of the car. (Reduce the signal strength, but do not affect the positioning). The above is the reason I learned by asking the customer service of Shanghai Gumi Company. I hope it will help you!
