Now that we understand what GPS tracking is, let's understand the types of trackers available on the market. There are three:

Satellite

This type of tracker sends the signal to a satellite network that distributes the precise location of the vehicle to the tracking centre. It works well in open environments, but it is expensive and does not transmit in real-time. For GPS fleet management this is essential.

Radiofrequency

This tracker is often used to track stolen cargo. It is a very simple device, so it often ends up not satisfying the needs of complete management of the vehicles in the fleet.

M2M / GSM

The most modern models usually use this technology, which transmits the signal to telephony antennas. Pay attention to how the data is made available, as this can interfere with updating information in real-time.

Features in vehicle tracking systems

In the tracking carried out by a conventional network, the device is connected to the cellular telephone network, through the operators themselves, who are responsible for installing and maintaining the “base radio” stations - those huge antennas that we see in some parts of the cities.

• Therefore, if there is not one of these towers at any point on the route to be followed by the vehicle, the sending of data by means of signal capture will only occur or resume when such a structure is identified.
• As a result, the information will not arrive on the device in real-time. The user will receive the data as soon as he/she passes through an area with signal coverage.

Conclusion

In the case of satellite sending, if the vehicle is in the middle of a forest or region where the internet signal may suffer interference, the tracker will send the data, as soon as it “recognizes” the receiving satellite. He, in turn, will resend the data to some point on Earth, until the information reaches the "cloud".
