How a car GPS tracker works and what types exist

In a world where car theft remains a real threat, GPS car trackers have become an essential tool for many drivers. But how exactly do they work? And what types are on the market? In this guide, we explain clearly, so you know which one to choose and how to get the most out of it.

What is a GPS car tracker?

A GPS tracker is a device that uses satellite signals to determine a vehicle's exact location. This information is sent to the user via a mobile app or web platform, allowing them to view the vehicle's position in real time or view their travel history.

They are used for both personal and professional purposes: from protecting a private car to managing fleets, monitoring company vehicles, or monitoring young drivers or employees.

How a GPS car tracker works

The GPS (Global Positioning System) works thanks to a network of orbiting satellites that constantly send signals. The tracker receives these signals and, through a triangulation process, determines its location.

Depending on the model, there are two main ways to receive this information:

1. SIM card locators:
   They transmit their location via the mobile network. They require a SIM card with data or credit, and allow you to view your location in real time from your mobile phone.
   Example: devices with their own app, parental controls or fleet management.
2. SIM-free locators (loggers):
   They record the route in an internal memory, but they don't transmit the location in real time. You must connect the device to a computer afterward to view the data.
   Example: more useful for path analysis, not live tracking.

Types of GPS car trackers

There are several types depending on how they're installed, how they're powered, and what functions they offer. Here are the most common:

1. Plug-in locators (OBD)

• They connect directly to the car's OBD port (usually under the steering wheel).
• They feed on the vehicle itself.
• Easy to install, yet visible and easy to remove.

2. Locators with internal battery

• They operate autonomously.
• They can be easily hidden anywhere in the car.
• The battery can last from days to several months depending on usage and model.

3. Wired locators

• They connect directly to the car battery.
• They offer a more professional and discreet installation.
• Ideal for fleets or long-term use without worrying about charging.

4. Magnetic locators

• They incorporate magnets to fix them to metal parts of the vehicle (such as the chassis).
• Very easy to install and hide.
• They are usually autonomous and have rechargeable batteries.

Additional features that may include

• Motion or vibration alerts
• Safe zones (geofences)
• Route history
• Remote engine cut-off (on some advanced models)
• Built-in microphone to listen to the surroundings

Conclusion

GPS car trackers are very useful tools for both improving security and more efficiently monitoring vehicles. Understanding how they work and what types exist is key to choosing the right model for your needs.

Whether you're trying to prevent theft, monitor routes, or simply know where your car is at all times, a good GPS tracker can make all the difference.
