GPS Tracking devices offline reasons

- Apr 14, 2018-

1. The status of the SIM card in the vehicle GPS locator is in arrears.

Solution: Contact the network operator to pay and restart!

2. The GPS Tracker is dead.

Solution: The gps locator tracker will be offline when it is shut down or powered off. The first step is to use the mobile phone to dial the device's SIM card number. If it fails to open and send a short message to the device number, there is no reply: the device is powered off or is The current and voltage of the power supply line are unstable.

3. The communication module (GSM module) of the gps locator tracker has a problem.

Solution: Contact the factory to replace the GSM module!

4, in the signal blind area, such as vehicles in the underground parking lot, the tunnel signal weak area

Solution: This situation is a relatively common situation. The platform can not receive the information of the GPS locator in the vehicle and it is recommended to leave the area with poor signal.

5. The antenna of the onboard GPS locator is broken.

Solution: Can only be replaced!

6, the SIM card is not in good contact;

Solution: Reinstall the SIM card

7. The gps locator tracker module has a reduced sensitivity and cannot be located.

The sensitivity of the GPS receiver is mainly determined by two aspects: one is the gain and noise performance of the entire signal path of the receiver front-end, and the second is the algorithm performance of the baseband part. Among them, the front end of the receiver determines the signal-to-noise ratio when the received signal arrives at the baseband, while the baseband algorithm determines the minimum signal-to-noise ratio that can be tolerated during demodulation, capture, and tracking.

Solution: Choose a manufacturer with high sensitivity

8. The gps locator tracker is installed near a metal object and the device does not receive GPS signals from satellites.

9, the device is off (not powered or no electricity)

Solution: Let the device is in the boot state; check the amount of electricity on the landing monitoring platform (mobile phone APP, computer platform) to determine whether there is electricity;

10, the server did not receive the reported data

Solution: There may be a problem with the equipment in the GPS positioner on the vehicle, or it may be a problem with the server. Customers can be contacted in a timely manner to clearly indicate the situation in which the device does not report data or is offline, so as to better solve the problem.
