GPS

Global Positioning System


Common Infos

GPS is a satellite-based radionavigation system developed and operated by the U.S. Department of Defense. GPS permits all users free of charge to determine their three dimensional position any time, any weather, anywhere in the world.
Have a look at the GPS Resource Library or at this Garmin page for more informations about GPS.

The russian counterpart of GPS is GLONASS. You rarely get receivers which support GLONASS.

The U.S. Coast Guard Navigation Center provides interesting informations about the current status and plans of the GPS (2001-10-01).

The precision of GPS for civilian use is about 20 metres since the SA (selective availability) was turned off on May, 2nd 2000.

Garmin GPS 12XL

Personally I own my second Garmin GPS 12XL. The first one (bought aroung 1997) was not waterproof as advertised and filled with water during a heavy tropical rain shower in Antigua while sailing. Garmin replaced it free of charge with the newer hardware revision and this unit seems to be really waterproof.
The newest firmware and manual can be downloaded from Garmins support page.
