The other day, my father was watching a program on TV and he asked me if GPS tracking would work in the sea. Yes, as far as I know, GPS tracking works as long as the device could receive a signal from one of the 24 GPS satellites of the Department of Defense that continuously orbit Earth.

I have seen how well GPS works once when I got lost in my own city and how efficient this technology is for my friend who owns a fleet of trucks. It helps him keep tab of the speed his drivers drive the trucks, whether they have detoured elsewhere to do their private business and especially when a vehicle breaks down in the dead of the night; at least the office knows exactly where the driver is stranded and would dispatch assistance and substitute vehicle over.

I was watching YouTube earlier this evening and came upon this video on how GRP tracking could aid murder investigations as well.

But you know what? If there are rich people who are driving those cars that we see on The Gem of Life, they should also embed a GPS tracking key onto the car in case of car jacking. The device is small enough that it would not be noticeable. It would not have a problem sticking under the vehicle and is water resistance too.

Even though a GPS tracking key is small in size, it is very powerful. Also, what makes it a popular tracking device is its USB-compliance and compatibility with Google Earth.
