Vehicle Tracking Devices And Its Parts

Interestingly, the ability to utilize a complete vehicle tracking system does not require too many hardware components on part of the user. In fact most vehicle tracking systems are comprised of only two sets of hardware devices, the transmitter and the remote receiver. While different communication protocols (GPRS, radio frequency, GPS) may require a different set of hardware components, these components mainly differ in configurations only and the same equipments along with their functions are still left intact.

Transmitter:

The transmitter is an electronic device that is responsible for propagating a signal to be intercepted by the receiver. Depending upon the configuration of the transmitter, it can emit signals in the form of radio waves for radio frequency-type vehicle tracking systems, it can emit microwaves for satellite-based vehicle tracking systems such as GS, or it can also emit electromagnetic waves for cellular-based GPS.

A transmitter is composed of the following basic parts:

Power supply - The power supply (or power supply unit) is a device or system used to supply electrical energy to the transmitter.

Oscillator - The term "oscillator" refers to the electronic circuit within the transmitter that produces a repetitive signal.

Modulator - The modulator is a device that varies the static waveform within the transmitter. By performing this process, it is possible to form messages out of the variety of signals produced.

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.

There are many other in-depth references such as guide books that tackles deeper topics regarding the transmitter and the receiver electronic devices.
