Marine GPS Systems Applications

Marine gps as a specialized adaptation of current gps (global positioning system) technologies that allow it to be used for navigation on water. When used for marine applications, marine gps systems can be used to plot or steer a course, navigate a ship in bad weather, or even during sightseeing activities. While gps has been in existence since 1973 as a United States Department of Defense (DOD) project that overcame limitations of previous navigation systems, it has only been in the last decade and a half that the technology has been accessible to the average consumer. It provides reliable location and time information at any time and in all kinds of weather, anywhere on or near the Earth's surface, making this space-based global navigation satellite system the most popular means of obtaining this kind of data. Unobstructed line of sight to at least four of the orbiting gps satellites is required for a navigator equipped with marine gps systems to take advantage of digitally precise orientation and velocity measurements. Your navigation system's built-in features will largely be decided by your allotted budget. Remember your needs as a navigator and purchase only the functionality that you need. These systems come in a variety of sizes, ranging from small handhelds to large units that are mounted onto navigation stations, and are also available on a variety of platforms that can be paired or linked with desktop or laptop computers, built into cellular phones that improve the phone's functionality, or as stand-alone systems such as you would expect with a marine gps handheld used by fishermen. When selecting a navigation system that is best for you, the first consideration aside from your budget, should always be your boating style.Your first consideration, aside from your budget, should always be your style of boating when it comes to selecting a navigation system that is best for you. A small handheld device should suffice if you are a hobbyist that kayaks on area rivers or a casual fisherman. On the other hand, a gps system with a larger screen that is mounted to your ship's navigation system would be more appropriate for your needs if you prefer to cruise on larger boats from port to port or perhaps choose to fish a little further offshore. You can typically expect to shell out around $200 for entry-level handhelds, but it should be noted that not all portable gps systems are waterproof or ideal for marine conditions. Chartplotters, or fixed-mount gps systems generally come with larger and more readable screens and more functionality and will start costing you around $900. Other multi-function marine electronics have gps built-in along with radar and fishfinders with price tags that go upwards of $4000. Remember to shop around brands and try the unit out before you decide to make a final purchase.
