Why is the pet location device inaccurate?

During the use of pet location devices, we may encounter inaccurate positioning. For example, we search for pets based on the location displayed on the mobile app. At the location marked on the app, it was found that the pet was not there. We looked around and found the pet nearby. This imprecise positioning does not affect our use. But I can't help but wonder: why is the pet location device not accurately located?

Principle of pet location device positioning

Before understanding why the pet location device is inaccurate, we first need to know the positioning principle of the pet location device. The positioning technology of pet location device is mainly based on GPS positioning. Receive satellite signals through the built-in GPS receiver. Then calculate the coordinate data. Upload to the backend system through mobile communication network. The full name of GPS is Global Positioning System.

Why is the pet location device inaccurate?

The positioning accuracy of the GPS module is 5 to 10 meters. This is also why pet location devices cannot be completely precise. Positioners all have an allowable accuracy range. The positioning accuracy of GPS modules depends on many factors. For example, satellite clock and orbit differences in GPS systems, number and distribution of GPS satellites, atmospheric effects, solar radiation, multipath effects, etc. Meanwhile, due to factors such as the quality of the antenna and feeder, antenna position and direction, testing time period, weather, etc. All of these will cause different positioning errors in the pet location deviceGPS module. PCB design can also affect the positioning accuracy of GPS modules.

How to make the pet location device more precise?

An effective way to make pet location devices more accurate is to improve the positioning accuracy of the GPS module. The application of new technologies can effectively improve the positioning accuracy of GPS locators. Many pet location device manufacturers have started using dual band GPS positioning technology. Dual frequency GPS positioning technology can improve the positioning accuracy of locators. Dual frequency GPS can receive two types of frequency signals simultaneously. This can eliminate the influence of the ionosphere. Thus improving the positioning accuracy of the locator in open environments. The accuracy of pet location devices using dual frequency GPS modules can reach 3-5 meters. Dual frequency GPS positioning technology makes pet location device positioning more accurate.
