Digital antenna Positioning

The GPS150 DualNav™ positioning sensor combines a brilliant precise 50 channel GPS with GLONASS, the Russian funded satellite placement system that is today on the web and providing a great back-up or substitute for GPS. This “smart” sensor will automatically switch involving the methods and/or individual can by hand select the best suited due to their task. The GPS150 is likewise in a position to utilise the European funded Galileo placement system in regards on the web (IOC – preliminary procedure capacity in 2018).

The utilization of GLONASS as yet another satellite placement system has become the biggest action improvement in maritime navigation since GPS ended up being totally augmented back in the middle 90’s. Digital Yacht’s GPS150 utilises the standard NMEA information format enabling older chart plotters plus existing generation items to make use of this brand new technology. The GPS150 additionally allows the user to pick many different different NMEA baud rates (4800, 38400 and 115200) to allow interfacing with history and present methods. In addition it supports a fresh TurboNav™ mode that will attract racing yachtsmen and gratification people in which GPS/GLONASS information is output at 10Hz (10 x faster change than usual) in accordance with an interface rate of 115200 baud that will be 24 x the rate of typical NMEA information. This massively improves sluggish rate navigation data including providing the most useful course and speed data in a dynamic circumstance.

The GPS150 houses most of the electronic devices in its small 75mm antenna and has now an individual multi core cable for power and data. Energy usage is 30mA at 12V. It can be utilized as a straightforward placement sensor for plotter or VHF DSC systems in addition to a precision, high speed sensor for performance sailing/super yachts. Setup is not difficult with a block of easy internal switches establishing the traits of this product. This enables the unit is programmed in the field without professional computer software or development tools.

The GPS150 can also connect with the WLN10 wireless screen to allow information become delivered to cellular devices particularly iPhones, iPads and Tablets. Additionally there is a USB screen for Computer and MAC people (ZDIGUSBNMEA).

GPS now GLONASS
Knowing your role whilst at ocean is vital to safe navigation. That which we now take for granted, had been extremely difficult, time intensive and inaccurate. After that, into the latter 50 % of the 20th century, came the electric positioning methods – Decca, Loran, Transit and in the 1990s, the global positioning system, GPS.

Over 20 years have actually passed away because the very first GPS receivers were commercially readily available plus this time depends upon has arrived to rely on this United States funded technology. Today every watercraft, jet, automobile and train that we travel on features gps device and also your cell phone will give a GPS place accurate to within 10m, anywhere in the world, on touch of a button.

Much governmental discussion has taken location over our dependence on GPS technology, to the level in which both Europe (Galileo) and Asia (Compass) tend to be establishing their very own satellite based systems, which are planned to be totally working by 2020. However, whilst GPS had been developed in the 1980s, there was another competitive system developed in Russia called GLONASS. This technique had been really over shadowed by the United states global positioning system and due to the privacy surrounding the technology together with problems for non-Russian organizations to license this technology, it never ever attained wide spread commercial use outside Russia and surrounding countries.

During Russia’s difficult financial duration between 1989-1999, federal government shelling out for their particular area program had been cut by 80% and launching of brand new GLONASS satellites stopped. With reasonably quick life spans the GLONASS satellites soon started initially to fail and by 2001 there have been just 6 satellites nonetheless working additionally the GLONASS service successfully ceased. Most observers at that time believed this could be the loss of GLONASS however in 2000, using the Russian economy recuperating, President Vladimir Putin took an unique desire for GLONASS making the renovation with this solution a high concern.

Between 2002-2011, a sizable investment ended up being made and at the termination of 2011 GLONASS was fully restored and now provides global coverage (with 24 working satellites) and reliability very nearly as good as GPS. In regions of high Latitudes (North and South) GLONASS is more precise than GPS because of the orbital place regarding the satellites.

DualNav™ – NEW TECH
Now with all the GPS150 DualNav™ technology, ship owners can have a single sensor that will instantly read satellite data from both GPS and GLONASS constellations, choosing the best indicators from over 50 satellites. Wherever you are in the planet you now have two times the satellites to select from causing the GPS150 receiver having definitely better coverage, time for you very first fix and positional accuracy. Add to this the newest large sensitiveness receiver design, selectable baud price and 10Hz position inform rate along with a GPS receiver that's dramatically better than every past marine GPS receiver on the market.

The brand new performance is particularly noticeable if receiver is attached below deck/inside the wheelhouse where in fact the large sensitivity receiver nevertheless gives a good place fix or when there are obstructions blocking the view of this sky, such as a wet sail shadowing the antenna or when cruising in streams or near to high cliffs, plus DualNav™ technology with additional satellites to choose from, offers a much more accurate fix.

On bigger ships, it is now feasible to own two completely separate place sources, not only two GPS units but two different positioning systems in order to compare and validate your actual position. Set one GPS150 to GPS mode and another GPS150 to GLONASS mode and you have double redundancy and two independent placement methods.
