How does 4g car gps tracker work

4g car gps tracker is a terminal with a built-in GPS module and a mobile communication module. It is used to transfer the positioning data obtained by the GPS module to a server on the Internet through the mobile communication module (gsm/gprs network), which can be realized on the computer. Or check the terminal location on the mobile phone.

4g car gps tracker precautions

1. Can't search for satellites at home. GPS works by directly receiving signals from American GPS satellites. You need to see the sky outdoors to receive satellite signals. It cannot be received indoors!

2. The battery life is short. All vehicle-mounted GPS batteries have a short continuous use time. Because there is a smoker power supply on the car, the designer thinks that there is no chance to use the battery for a long time. The battery is only used as a backup. 40 minutes to 1.5 hours, different models, different use, there will be big differences. It should be noted that the moment the car is ignited, the starting current is very large, and there is a risk of burning the car charger fuse. It is best not to plug the car charger into the cigarette lighter when the car is started, and then connect it after starting.

3. Inaccurate positioning. The normal GPS positioning error is within 10-20 meters, which is affected by many factors such as weather, the US GPS policy, and sometimes it is even greater. If the location indicated on the map is not very accurate on the road, the reason may be the error caused by the delay caused by the poor signal, or the occasional deviation of the map data, or the road is very wide, so it seems that the GPS is stably off the road.

4. Can't search stars or search stars slowly. Don't worry if you can't search stars or search stars slowly, please change the location and time and try again. Don't use it once or twice, or a day or two to determine the quality of GPS. Because the satellite status is different every day, maybe the same place, the signal is full in the morning, but the signal is almost in the evening.
