Satellite Signals ：
The Autool X90 inclinometer receives GPS signals via satellite transmission. Large obstacles like underground parking, tunnels, skyscrapers etc. interfere with the search for GPS signals, which usually results in the speed data not being readable. Meanwhile, there is some error in the elevation data in a range of 5 to 100 meters in low elevation areas, while the error in elevation areas can be ignored. The cause of this error is related to satellite signals.
