A car tracker GPS is primarily used for security purposes wherein the car or truck or any vehicle can be tracked from anywhere in the world if it has a GPS receiver inside and the tracker is connected to the internet. A car tracker GPS device receives signals from the GPS satellite and using that determines the position of the car or truck on the Google earth or Google maps software.
Apart from position, other data can also be made available in a car tracker GPS system. They are the start and stop facility which would give you the information like when the car was started, how many kilometers it has traveled, where all it was stopped en route and also the speed details of the object in scrutiny.
When you need to compare car tracker GPS of different make, you should look at the accuracy and the size of the device. When it comes to accuracy, it becomes the most important parameter to look for since position is why a car tracker GPS is bought and hence the position that the device records must be accurate and there can be no compromise on this. The normal position accuracy that is available in markets today is up to 10 feet which is fair enough to track a car real-time. Also, time accuracy is very high up to one second of a motion which ensures fast tracking.
There are many car tracker GPS makes which come in miniature sizes and can be kept almost anywhere. They are extremely handy and can be taken wherever you travel.
The car tracker GPS is also used to track stolen cars. The GPS system which is very small is usually not seen by a person stealing a car. However, the owner of the car can easily track his vehicle and find out in minutes where his car is traveling by logging on to his account from even a nearby browsing centre.
The car tracker GPS has thus helped the investigative agencies and the police a lot in their enquiries and investigations.
The car tracking GPS can also be used by fleet services to monitor the activities of their drivers, used by people who send their teens in cars driven by drivers and also by spouses for monitoring the other's movements.
