A GPS tracking unit is a device that uses the Global Positioning System to determine the precise location of a vehicle, person, or other asset to which it is attached and to record the position of the asset at regular intervals. The recorded location data can be stored within the tracking unit, or it may be transmitted to a central location data base, or internet-connected computer, using a cellular (GPRS or SMS), radio, or satellite modem embedded in the unit. This allows the asset's location to be displayed against a map backdrop either in real time or when analysing the track later, using GPS tracking software.

Law enforcement. An arrested suspect out on bail may have to wear a GPS tracker, usually an ankle monitor, as a bail condition.

Race control. In some sports, such as gliding, participants are required to carry a tracker. This allows, among other applications, for race officials to know if the participants are cheating, taking unexpected shortcuts or how far apart they are. This use has been featured in the movie Rat Race.

Espionage/surveillance. When put on a person, or on his personal vehicle, it allows the person monitoring the tracking to know his/her habits. This application is used by private investigators.

These devices are also used by some parents to track their children.[5] The supporters claim that if cleverly used, this actually allows children more independence.

GPS personal tracking devices assist in the care of the elderly and vulnerable. Devices allow users to call for assistance and optionally allow designated carers to locate the user's position, typically within 5 to 10 metres. Their use helps promote independent living and social inclusion for the elderly. Devices often incorporate either 1-way or 2-way voice communication which is activated by pressing a button or sliding a switch. Some devices also allow the user to call several phone numbers using pre-programmed speed dial buttons. Trials using GPS personal tracking devices are also underway in several countries for use with early stage dementia.

Internet Fun. Some Web 2.0 pioneers have created their own personal web pages that show their position constantly, and in real-time, on a map within their website. These usually use data push from a GPS enabled cell phone or a personal GPS tracker.

Solar Powered. The advantage of some solar powered units is that they have much more power over their lifetime than battery powered units. This gives them the advantage to report their position and status much more often than battery units which need to conserve their energy to extend their life. Some wireless solar powered units, such as the RailRider can report more than 20,000 times per year and work indefinitely on solar power eliminating the need to change batteries.

Animal control. When put on a wildlife animal (e.g. in a collar), it allows scientists to study its activities and migration patterns. Vaginal implant transmitters mark the location where pregnant females give birth.[6] Animal tracking collars may also be put on domestic animals, to locate them in case they get lost.

It’s a common practice for state, municipal and private fleets alike. Whether you operate a government agency or a business, time is money. Misuse of company vehicles cannot be tolerated.

What You Can Do

So how do you hold your employees accountable? As we mentioned above, GPS vehicle tracking is becoming more common at a commercial and state level. Satellite tracking allows a company to observe the precise position of a company vehicle, often in real-time. If a vehicle deviates from its assigned route, you know right away.

The Value of Discrete Tracking

If you want an accurate picture of how your vehicles are being used, a strong argument exists for being discrete with your GPS tracking device. If employees know they are being tracked, they can take steps to cover their tracks or make excuses for questionable driving patterns. This does little to solve the problem of misuse of company time.

By being discrete, you can be more candid about your monitoring. You can identify actual trends and act accordingly.
