When opening the GPS positioning platform to check the driving trajectory, it was found that the route was quite chaotic and there was a lot of trajectory drift. The reasons for this situation generally include: firstly, the vehicle is equipped with a signal shield, which leads to unstable signal reception by the car locator; 2、 Vehicles pass through areas with poor GPS signals, such as tunnels, towering buildings, airports, etc; 3、 Without turning on GPS for real-time positioning, car locators usually have base station positioning and GPS locators. Check if you forgot to turn on GPS in the app.

　　2. The car locator cannot be used normally when parking. It depends on which power sources are used to power the car locator. When connecting the car locator to the battery, it can ensure that the car can continue to work in a stopped state, but pay attention to the usage time as it may deplete the vehicle's battery.

　　3. There are two car locators on the same car, but the displayed positions differ greatly. Generally, two car locators are used in the rental or risk control industry. They will install two or more locators for safety reasons. Generally divided into wired devices and wireless devices, it is normal for location information to be different. Wireless devices, due to using their own power supply, use base station positioning or only start once a day to ensure standby time. Another situation is that the equipment is dismantled and detached from the car, resulting in inaccurate positioning information.

　　4. The car locator goes offline for no reason. Firstly, you can check if the surrounding area is a signal shielding area; 2、 Check if the SIM card in the car locator is overdue;
