GPS for Surveillance and Rescue
It is not only nice, it maybe a lifesaver! Suppose you have a cellular or a satellite phone, but you got lost somewhere. How can somebody tell you how to find your way out, if you are unable to describe your location?
And if you need rescue, how will they find you? Enter GPS, a friendly system that was originally developed for the military (US military that is, who else?), but is now accessible to everyone at no cost, besides the gadget one needs.
It consists in two dozen satellites circling the earth and broadcasting all time by radio. Quite simple and low cost instruments working on batteries, listening to the signals of three or four such satellites, are able to determine your coordinates with acceptable precision, anytime, anywhere, and possibly can show your place displayed on a map they carry with them.
How do delivery people find their way in busy cities or in deserted countryside? They print the address in the GPS based navigator which, knowing where they are at any instant, tells them by voice commands or on a map how to reach their destination.
Amazing, right? Next time you rent a vehicle on a business or pleasure trip, chances are you will find in the car a helpful and kind navigator at your service, to save your time and show you around whatever you are looking for.
So, what has this to do with surveillance? Well, with a simple twist of technology and by adding some extra functionality, enterprising manufacturers came up with other instruments you may find useful or necessary.
If you want to be able to check the whereabouts of your vehicles when they come back to the base, a simple tool hidden someplace under the hood can report to you times and route scoured from the last check.
But if you want to find where is your stolen expensive car, or even the truck with its precious load, another instrument can relay continuously its position in real time to a central office, with all the advantages that such knowledge provides.
By assigning one such instrument to every vehicle of a whole fleet, management can monitor and direct any changes of travel program in real time, satisfy customers and save on delivery expenses.
As soon as you will find the best use to put GPS to work for you, chances are you will ask: "How could I manage without it till now?"
