What Makes A Vehicle Tracking Device?

By Salvador Paez

It's nice to know that there are vehicle tracking systems that help protect and locate vehicles. For many car owners, this is a very important and useful device. Even so, they'll admit that they don't know much about these mechanisms. Well, one interesting fact about vehicle tracking systems is they just have two types of devices that help them work. These are the remote receiver and the transmitter. Although the different communication protocols use various kinds of hardware components, the only thing that distinguishes them are their configurations. Their functions and equipments remain the same.

The Transmitter:

Responsible in sending the signal to be received by the receiver, the transmitter is one of the most important electronic devices of vehicle tracking systems. The signal it emits can come in various forms, depending on its configuration. For cellular-based GPS, small electromagnetic waves are used. If the vehicle is a radio-frequency kind, the type of signal comes in radio waves. Microwaves are used for systems using satellite tracking, like GS.

There are several basic parts that make up the transmitter:

Modulator - This part works by making messages from different kinds of signals produced. It's found within the transmitter, and processed the static waveform in it.

Oscillator - This is the circuit in the transmitter that makes the repetitive signal.

Power supply - It provides electric energy to the transmitter.

Amplifier - The amplifier does as its name suggests; it amplifies the signal of the transmitter large enough for the receiver to intercept.

Receiver:

The receiver is the remote component that is tasked to intercept signals from the transmitter to be able to determine its exact location and among other important details. The type of receiver used depends on the type of transmitter; radio receivers for radio frequency-type transmitters, etc.

To help you learn more about vehicle tracking systems and its transmitter and receiver, you can do more in-depth research. Guide books will help you learn more about these electronic devices.
