Do you have a ship and a mobile phone? Probably you are planning to know about the latest navigation apps. Looking at the different kinds of softwares, Marine GPS Navigation Softwares seems to very helpful in many different ways. With the right marine navigation software in your hand, you can turn your mobile phone into a full-blown chart plotter. This means you have the back-up to electronics easily available to you when you need it, and carry the tech with you when taking boats or ships without any electrical systems.
What happens if you are lost during the fishing or boating tour will be the scariest nightmare that you will want to ever face? For this reason, the reliable and best navigation software is very important for any tour. There are many good navigation softwares provided by companies like amnautical.info etc which can make your ship journey safer and better. But one thing you need to know is the navigation software may cost you quite a lot, so make sure you invest carefully.
How does the Navigation GPS Works?
First, let us look at how this GPS receiver comes to know where their satellites are situated in space. This GPS receiver picks two types of the coded information from their satellites. One is called “almanac” data that has approximate positions of satellites. And this data is transmitted & stored in the GPS memory receiver thus it knows the orbits of these satellites & where every satellite must be. An almanac data is updated periodically with the new information as satellites move over.

The satellite can travel out of orbit, thus the monitor stations keep proper track of these satellite orbits, location, altitude, as well as speed. These ground stations send orbital data to their master control station that sends the right data to the satellites. The exact and corrected position is called “ephemeris” data that is valid for 4 to 6 hours and can be transmitted in coded information to its GPS receiver.
Thus, having received ephemeris and almanac data, the GPS receiver knows its position (or location) of satellites at every time.
Why Do You Want GPS?
It is very important you know what type of boating you do. If you are an inland waterways user, then GPS will very useful but not very important. Suppose you are lost on a lake, then keep pointing your boat in just one direction, and you will hit the land. But, the sonar facility on your GPS unit may come in very handy for the shallow waters.
This GPS system has the use when you explore any rugged terrain. Boaters are generally outdoor types and keen to get out in nature & see beautiful lakeside forests and islands. For them, a hand-held GPS unit will be invaluable. It can allow you to explore the wild area with the knowledge technology keeps you safe.
But, for ocean-going yachts, this scenario is a bit different. A good GPS system is a life-saver. This helps you to plot the journey, even in the deepest & remote sea because satellite umbrellas are protecting you.
The best rule is: If you are surrounded by ice and water, and you do not have any clue where you must go, probably you must have packed the GPS unit. Do not leave your shore without the GPS unit, not if you are able to read stars, and read the map of oceans through charts.
Is GPS Unit Accurate?
Around 95% of the time, the accuracy of GPS is within. In some worst- cases, accuracy will degrade to 25 – 26 feet. Just to ensure proper accuracy, the GPS antenna must have a clear and unblocked sky view. The blockage will limit the satellite-signal reception that diminishes its accuracy. You need to check the GPS’s status screen. It’s a good indicator of the satellite reception, strength as well as positional accuracy.
You need to create the benchmarks, like your position in the slip, at navigation aids & familiar landmarks, confirming your GPS will be experiencing the normal accuracy. Make sure to keep your GPS app & cartography updated. Installing an external antenna, instead of relying on the internal one, will be the simplest way to improve GPS accuracy.
Cruising is lots of fun, particularly if you’re going to a place you aren’t much familiar with. However, this will lead to disaster in case your trip will include you endlessly looking for the right route.
