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.
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.
There are several basic parts that make up the transmitter:
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 - It works by intensifying and increasing the signal sent by the transmitter, so the receiver can intercept it better.
The Receiver
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.
