The X90 receives GPS signals through satellite transmission.Large obstructions such as the underground parking lot, tunnels, high-rise buildings, etc. will interfere the GPS signal searching, which normally lead to failure to read the speed data. Meanwhile, there is a certain error of altitude data within a range of 5 to 100 meters in low altitude
areas, while the error in high altitude areas can be ignored. The causeof this error is related to satellite signals.
