What is the accuracy margin of error for the 4g long standby

  • In daily life, the positioning accuracy of the 4g long standby asset tracker on the electronic map is expressed as the distance from one coordinate point to another reference object. The reference object can be a store, a factory, a building, or a community, but it is only a coordinate point reflected on the electronic map. The location and latitude and longitude of the coordinate point will give people a different experience and feeling.

    There are many factors that cause the error of the 4g long standby asset tracker, so what is the accuracy error range of the GPS tracker?

    Some people say that the error is less than or equal to 5 meters, and some people say that the error is less than or equal to 20 meters. According to the relevant data, the accuracy error parameter of the civilian GPS locator is less than 10 meters, but these are only reference data, such as the fuel consumption per 100 kilometers and The cruising range of an electric vehicle is determined by specific conditions, such as load, speed, road conditions, etc. The main reasons for the error of the car GPS locator are as follows:

    1. The GPS positioning accuracy of the vehicle is related to the area, terrain, time and positioning mode of the vehicle. For example: in underground garages and mountainous areas, GPS positioning errors will occur.

    2. Base station positioning is related to the density of base stations in the area where it is located. For example, if the vehicle is in an urban area and a remote mountainous area, the density of base stations must be different, which will cause GPS positioning errors.

    3. The phenomenon of satellite drift sometimes occurs when it is static, and it is more accurate when it is dynamic. At the same time, it will also be affected by the upload interval and network delay.

    However, the technology is now quite mature, and the daily accuracy can be fully satisfied, so there is no need to worry about the impact of GPS vehicle locator errors on practical applications.
