GPS stands for Global Positioning System. Created for the military, a GPS can work anyplace in the world. It utilizes satellites in space to give you the latitude and longitude for your precise position on the land or water.
There are a lot of models on the retail market; Garmin, Raymarine, Furuno to name a few. They all achieve the same thing, but some have extra gadgets. It's all about your individual preferences. For more information regarding Garmin Plotter, you may browse this website.

If the GPS has a built-in antenna, it is ready to operate after you connect the power connections. You must have a clear view of the sky as a yacht hardtop will prevent the GPS from receiving satellite signals. In reality, installing it high can produce course and speed variations due to the yacht pitching.
As soon as you activate your GPS receiver, it will start to obtain signals from all satellites in its view. It will need a couple of minutes to identify and lock on to the satellites that can provide the greatest fix for its location. If you are turning the machine on for the first time, or if it has been relocated a long way since it was previously on.
The GPS receiver will lock on to at least three satellites to triangulate its position. A good number of GPS displays will have some kind of status screen at the same time as the receiver is gathering information from the satellites. A few GPS devices also provide you with a satellite location.
