– (2) The car factory had increased speed(5-7%)than real for drivers’ safety,satellite data is strictly follow the international standards
– (3) Fine-tuning the vehicle speed, e.g. meter display 100 Km/h, machine display 105Km/h,default value 107-5=102
– After the vehicle speed exceeds 5KM / H, the direction can be displayed normally.
– Under the underground parking lot, tunnel, under the overpass, there will be unstable satellite drift when there is obstruction.
