Vehicle tracking systems are dead useful. They help prevent car theft and they solve crimes. These are very efficient devices, but do you know how they work? Vehicle tracking devices are very interesting. The user doesn’t need too much hardware components to use it. These are only made of two kinds of hardware devices: the remote receiver and transmitter. Although various communication protocols such as GPS, GPRS and radio frequency need different kinds of hardware materials, these components only differ in terms of their configuration. The usual equipment and their functions still remain the same.
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 – The term “oscillator” refers to the electronic circuit within the transmitter that produces a repetitive signal.
Power supply – It provides electric energy to the transmitter.
Power supply – This is the unit that provides electrical energy to the transmitter.
The other part of the transmitter, this is a remote device that works by intercepting the signals sent by the transmitter. The primary use of this is to determine the specific location of the transmitter. Receivers can vary, depending on the kind of kind of transmitter used.
There are many other in-depth references such as guide books that tackles deeper topics regarding the transmitter and the receiver electronic devices.
