A new generation of relatively cheap GPS-equipped devices is allowing people for the first time to keep constant tabs on their rebellious teens, wandering spouses or loafing employees, leading some to be concerned about the eroding sense of personal privacy.
The myriad benefits promised by the launch of new positioning systems are opening up a future where we need never lose our way - or our mobile phones - and where our movements may be tracked around the clock by a "spy-in-the-sky".
Advances in underwater surveillance and satellite technology are revolutionizing marine biology by making it possible for biologists to tag and release animals and recieve daily emails on their location and health.
Personal location devices are beginning to catch on, largely because cellular phones are increasingly coming with a built-in tether. A federal mandate that wireless carriers be able to locate callers who dial 911 automatically by late 2005 means that millions of phones already keep track of their owners' whereabouts. Analysts predict that as many as 42 million Americans will be using some form of "location-aware" technology in 2005.
Sophisticated software and hardware are giving wildlife trackers an almost instant overview of plant and animal patterns. Ultimately, this will offer scientists a more profound understanding of how nature interacts.
The authors warn that location-based surveillance technologies could be used by repressive regimes to enslave populations.
Jerome Dobson worries that 1984 may be just around the corner. Dobson, a University of Kansas research professor and president of the American Geographical Society, is concerned that technical advances carry the potential for bringing about George Orwell's nightmarish vision of a society that destroys privacy. This new threat, says Dobson -- a respected leader in the field of geographic information technologies -- is "geoslavery."
The Economist covers the new generation of tracking devices that combine GPS technology with mobile-telephone chips.
Corrections officials are using GPS satellites to monitor 1,200 offenders nationwide as a condition of their parole or probation or as a form of house arrest. They are a small but growing fraction of the 150,000 offenders in the United States who are subject to more established forms of electronic supervision like home monitoring systems and mandatory telephone checks.
A lengthy article on the progress towards quantum computing and the possible applications that may result including improved GPS accuaracy and novel surveillance techniques.
