Vehicle GPS Tracker Frequently Asked Questions and Solutions

2019/5/18 14:01:41

After doing GPS Tracker products for so long, the following are some of the problems and solutions that customers often encounter.

 

1. After installing GPS Tracker, what is displayed on the platform map is not the location of the vehicle?

 A. There are several reasons for this.

First, the vehicle positioner has just been installed, and the vehicle is in a stationary state, the device does not want the server to transmit new location information. So the old positioning data is displayed. Just let the car go out for a few minutes to update the location information.

Second, the signal conditions of the environment in which the vehicle is located are relatively poor, and the GPS satellite cannot be completely searched, resulting in the vehicle GPS Tracker not receiving the signal.

Third, the installation problem, the installation location is too closed, it is not easy to search for satellite signals again after the satellite signal is interrupted. If this problem occurs multiple times, it is recommended to adjust the installation location.

Fourth, whether the SIM card is used normally.


2. After the remote power cut on the GPS platform, why can the vehicle still drive spontaneously?

A: Make sure that the GPS Tracker relay is wired correctly. In addition, the GPS Tracker must be connected to the server. The vehicle is in a “stationary” or “driving” state, and the vehicle speed is below 20 km/h. If the GPS Tracker is offline, not positioned, or the vehicle speed is higher than 20 kilometers per hour, the GPS Tracker will not cut off the power even if the remote power cut is successful.

3, send a mobile phone command to the vehicle GPS Tracker, why there is no reply or reply error

A: The total situation is generally related to SIM cards and signals. You can check the status of the SIM card:

First, dial the number on the GPS Tracker SIM card of the vehicle to see if it is owed

Second, check whether the SIM card has a GPRS traffic plan and SMS service.

Third, the signal is poor in the area, and the SMS gateway is delayed.

 

4. Why does the data in the running statistics not match the actual situation? Does the mileage statistics match the actual mileage?

A: The running statistics function on the monitoring platform is based on the location information uploaded by the GPS Tracker to the monitoring platform. GPS Tracker location information may be subject to signal, environmental, and fault factors. In other words, if the GPS Tracker is offline or not located, and there is no accurate location data, the data of the running statistics may automatically retransmit some data, but this will have some errors with the actual route. Therefore, the operational statistics on the monitoring platform can only be used as a reference.

5, the vehicle's trajectory is not correct, the drift is very serious?

A: This problem is usually caused by poor satellite signals.

First, when our vehicles are driving or stopping, they usually encounter tunnels, high-rise buildings, or places with more trees. In this case, the GPS signal will be weaker and even completely shielded, and the equipment will not receive the signal. There will be a phenomenon of inaccurate positioning.

Second, when the GPS signal of the device is interfered or the signal is blocked, the device will automatically switch to base station positioning or WIFI positioning according to the strength of the surrounding signal source. When the peripheral base station signal is strong, the device will automatically connect to the base station for positioning.
