Owners who have used the onboard magnetic gps tracker know that sometimes the GPS will cause the actual position of the vehicle to be inconsistent with the position displayed on the GPS map for some reason, and there is a certain deviation. Some are one or two hundred meters, some are even more. As a professional automotive GPS positioning research and development brand, we want to tell you that the position displayed by the magnetic gps tracker is deviated, as long as the distance difference is not particularly large. But one has to ask, what is the normal error distance?

1. Error range of military and civilian magnetic gps tracker

magnetic gps tracker is divided into military and civilian, military accuracy requirements are very high, so the highest difference of this locator is only one meter. When the civilian vehicle magnetic gps tracker is normal without interference, the error is within 10-20 meters, where the deviation is normal.

Second, the main reasons that affect the accuracy of magnetic gps tracker

However, the locator is an electronic product, and the car GPS is a long-term mobile work outdoors, so it will be affected by the driving environment such as weather, the number of GPS satellites and even the atmosphere, which will increase the position deviation on the electronic map.

In addition to weather, the positioning accuracy of the magnetic gps tracker depends on the region, terrain, positioning method and even the time of day. Like common underground garages, remote mountain areas, GPS positioning accuracy will be worse than urban areas.

3. Details that affect the accuracy of the magnetic gps tracker

In addition, owners often ignore two details: first, when the vehicle is parked in a position for a long time, this time refers to has reached a week or more, when the vehicle is used again to produce movement, the vehicle location information will be updated with a short delay of a few minutes. This also explains what some owners said on the Internet: "When the car is out for a distance, the positioning is still not moving."

Second, when we use GPS positioning navigation, we will find that the mark on the map is the distance between the point and the point, one point is the current position of the vehicle, and the other point is the reference object. The choice of reference objects is different, the distance and orientation will be different, which is one of the reasons why there is a deviation from the end position of the owner's imagination.
