The ability to know where a vehicle is or has been.
A GPS fleet tracking and car tracking device is often used for covert tracking of the driver in the car, throwing it into the "spy-equipment" class of products. The market for GPS real time vehicle tracking systems is considered as one of the fasted growing markets for GPS applications.
The two main categories of GPS car tracking device types are "passive" and "real time" systems.
Passive systems
store information regarding speed, time, direction and in some cases "driving habits" in memory. This memory is then downloaded to a computer.
Real Time vehicle tracking
sends its data at regular intervals to the manufacturer's database and the user reads the information through a website. There are some systems, which can deliver data directly to a user's cell phone on demand.
For car security, a car tracking device are fitted to a car "covertly", meaning it is hidden from view and there are no warning notices on the car to suggest that a tracking device is fitted. This makes a thief less confident about car crime and stops them trying to locate and remove the tracking system. Most police forces are now equipped with systems to track vehicles fitted with this technology.
The Global Positioning System, usually called GPS (the US military refers to it as NAVSTAR GPS), is a satellite navigation system used for determining one's precise location and providing a highly accurate time reference almost anywhere on Earth or in Earth orbit. It uses an intermediate circular orbit (ICO) satellite constellation of at least 24 satellites.
While the system on the whole is very accurate, it does have some problems and there are known variables, which could cause errors or misleading information. The largest causes for these errors are:
Nevertheless, a quality
car tracking device
offers some great surveillance capabilities and i encourage you to further investigate this type of spy equipment.
