By definition, GPS is a network of more than two dozen satellites that orbit the earth and transmit precisely timed signals down to GPS receivers.
Each receiver contains a tiny computer that uses the signals of three or four satellites to determine its location by using latitude, longitude and altitude coordinates that uses a process similar to triangulation.
Receivers can be programmed to calculate the speed and direction of travel as well. The data can be stored in the receiver for download onto a computer later.
For situations where remote access to the information is needed, some receivers can transmit it in real-time using cellular networks or satellite Internet connections.
GPS technology isn’t just for money grubbing bounty hunters and tracking deer’s in the woods.
In fact, some of the things the Global Positioning System is being used for in Canada will surprise you and make you nervous.
Many Private investigators use GPS to track people all over the globe sometimes.
Today private investigators place GPS receivers into “purses, knapsacks, gym bags, golf bags, and of course, into vehicles,” in order to track the person in covert surveillance operations.
Many cases involve one spouse wanting to know what the other one is doing when they aren’t together.
One situation in which a woman who had sought a PI’s services was given a GPS beacon to place in her husband’s golf bag.
The investigator was able to later demonstrate with the GPS tracking log that the golf bag had never left her husband’s parked vehicle during the time he had said he was golfing.
Besides tracking would-be cheating spouses, GPS tracking is being used in a lot of other ways. Parents can now place a mini GPS handheld tracking device inside a vehicle and easily tell if their misbehaving teenagers are where they say they are when they are out for the night joyriding or drinking at a bar.
And over the past three years, more than 120 visually impaired Canadians have been monitoring their location and getting around more easily with ‘talking” GPS units. Law enforcement agencies in particular have been finding GPS units very handy.
In May 2006, Nova Scotia became the first province in the world to use satellite-tracking GPS technology to follow offenders under house arrest. On any given day in the province, hard core convicts under house arrest total around 425.
Brian MacDougall, the electronic supervision co-ordinator for Nova Scotia’s Department of Justice, said: “It’s really holding offenders accountable.”
MacDougall added that the number of offenders tracked since May has fluctuated, but will reach 25 by the end of 2006.
In addition to ensuring subjects stay under house arrest, the system can be set up with timed “inclusion zones” that track offenders movements to ensure they attend mandatory appointments related to addictions or employment.
However sometimes the signal can be sometimes be blocked by things like overpasses or if the receiver is carried into a building.
But now there is the WorldTracker Pro Real Time Tracking System is a completely self-contained unit, ideal for the most demanding covert applications. Includes rechargeable Lithium Ion battery. No tracker is easier or faster to install. One-piece unit installs in seconds!
Using a laptop and cell phone, tracking is possible anywhere, even on the move! Tracking data can be viewed on any desktop or laptop PC. Data is directly downloaded through an encrypted cellular connection, giving you real-time location info.
The WorldTracker Pro’s GPS Tracking System is no lightweight GPS device as it maintains a data log tracks location, time, speed and the amount of time spent in one location for up to 20 days. The sleep-mode shuts down the unit after 10 minutes, drawing less power and not recording useless data. When the target moves the receiver automatically powers back up sending it’s location to any desktop or laptop PC.
