Navigating using a marine GPS (global positioning system) may be a bit more complicated than using GPS on land, merely because of the extra hazards lurking on and under the surface of the water. Actually, it may be tempting to reject the use of Marine Navigation because you're in a small craft that stays close to shore. This may be dangerous thinking because many of the hazards boaters come across are close to the shoreline.
However, there other things to think about when you decide to use this type of system. Don't rely only on marine GPS navigation. If you are going to spend time on the sea it is imperative that you know how to use a compass and charts in combination with location equipment.
With that in mind, you can begin to learn about Marine GPS Navigation and the way it works. The words "global positioning system" give a good indication of what this equipment can do. The system is designed to indicate to the boater, captain or pilot where the craft is located on the planet Earth. That's the simple explanation. The marine GPS unit on land or sea utilizes signals from satellites orbiting above to determine position. Based on signals from these satellites, GPS equipment provides map view and printed data for the people on board.
This is what the National Air and Space Museum says about the inner workings of GPS: "Each GPS satellite transmits data that indicates its location and the current time. All GPS satellites synchronize operations so that these repeating signals are transmitted at the same instant. The signals, moving at the speed of light, arrive at a GPS receiver at slightly different times because some satellites are farther away than others. The distance to the GPS satellites can be determined by estimating the amount of time it takes for their signals to reach the receiver."
As well as this necessary information, marine GPS navigation equipment may offer information about tides and ocean conditions, as well as other helpful information. Depending on quality of construction and features, marine GPS equipment may cost as little as $100 or more than $1,000. Equipment that can be used in various places on small craft require a powerful battery system. Several handheld units will serve the purpose for many boaters, though you should consider that you will be using the device in the open. Ensure the screen quality is good enough to be used in bright sunlight and other conditions.
Whilst the chart-plotter type of marine GPS equipment is a bit more expensive, there are distinct advantages with this method. These units use an overlay on nautical charts to display positioning. This equipment is generally larger in size and provides a superior viewing screen. Costs will be in the mid-range: around $500 or a bit more.
Marine GPS equipment is a vital piece of the puzzle for those who want to enjoy their time on the ocean whilst maintaining an air of safety on board.
