The Parts of Vehicle Tracking Devices
June 7, 2008 – 5:17 amInterestingly, 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 main purpose of this electronic device is to send off the signal that will be intercepted by the receiver. The signal can be in different forms, depending on the type of configuration the transmitter has. Electromagnetic waves are used for cellular-based GPS. Microwaves work for GS systems that use satellite tracking. For radio-frequency transmitters, radio waves work best.
A vehicle tracking system transmitter is made of several parts, including:
Power supply - The power supply (or power supply unit) is a device or system used to supply electrical energy to the transmitter.
Oscillator - It produces the repetitive signal, and is an electronic circuit found in the transmitter.
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.
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.
It can be a bit overwhelming to learn about vehicle tracking systems. To help you with this, you can do additional in-depth research. Guide books are very useful reference about these devices.
