GPS Personal Tracking

Personal tracking

Law enforcement. An arrested criminal out on bail may have to wear a GPS tracker, usually on the ankle, 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.[7] The supporters claim that if cleverly used, this actually allows children more independence.
GPS personal tracking devices are being used increasingly to 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 and Alzheimer's sufferers.
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.[8]
