HF AIS – Encapsulated in Digital Yacht AIS products for better performance

HF-AIS is an advanced technology that ensures an AIS transceiver reliably processes all transmissions in real time without error. An AIS transceiver with HF-AIS will typically allow you to see up to 30% more targets than transceivers without HF-AIS.  All Digital Yacht transponder products incorporate this technology brought to us by our chip set manufacturer SRT

You don’t know what you don’t see – if your AIS transceiver does not process (decode) an AIS transmission, you will not see that target on your display. This issue affects AIS Class A, Class B and receivers.

HF-AIS technology solves this critical and unseen issue, which can result in you missing up to 30% of available targets and data. An AIS transceiver can be required to receive and then decode up to 2,250 transmissions every minute – 37 every second – with each AIS transmission containing up to 300 bytes (your GPS position, MMSI, Speed, Course etc), that’s a huge amount of information that must be continuously processed. When this data is not processed due to the transceiver being overwhelmed with transmissions, the data is lost forever – often up to 30% of targets. The lost transmissions could be from a nearby vessel on a collision course with you – therefore lost data and targets are of critical importance to your safety.

  • Proven to see up to 30% more AIS targets and data with HF-AIS
  • HF-AIS ensures all available AIS transmissions are fully decoded and processed in real time.
  • HF-AIS is advanced core technology, that combines hardware and software, embedded in the ‘processing brain’ of our AIS transceivers.
  • HF-AIS is particularly beneficial in busy areas where the volume of AIS transmissions can cause processing errors and lost data in transceivers without HF-AIS.

HF-AIS technology is a unique combination of hardware and software embedded within
our AIS transceiver. It comprises a high performance processor (chip) which has the processing speed to easily cope with reliably decoding large amounts of data in real time
on which is highly efficient software that uses specialist architectures and structures
normally found in data heavy wireless applications such as 3G and 4G cellular phones.
This unique combination of hardware and software is HF-AIS and ensures that our
transceivers will reliably process all available AIS transmissions in real time and without
error.

The ultimate benefit is that you’ll get outstanding performance and the best AIS capability from our transponders.

Portable Navigation Solutions from Digital Yacht

More and more navigators are wanting a portable navigation solution either to move from boat to boat or have on their main vessel as a backup or easy installation solution.  The availability of low cost tablets and notebook PCs has made this really affordable and Digital Yacht have some great solutions to deliver professional navigation solutions from a portable package – and at great value too!

GPS Positioning – The Fundamental

A good quality GPS sensor with accurate positioning is the backbone of any modern navigation system.  Digital Yacht’s GPS150 DualNav GPS/GLONASS sensors provide highly accurate position, course and speed information with super fast updates and the GPS150USB makes an ideal positioning sensor for a notebook based navigation system.  It’s also powered directly from the USB port so there’s no extra cabling required.

The picture above show the GPS150USB with Digital Yacht’s SmarterTrack software running on a notebook PC.  More details HERE and also on SmarterTrack software which is a great solution for a PC allowing Navionics chart cartridges to be shared between PC and plotter.

Tablets, iPads and GPS…

Many tablets will have a GPS built in but some are very poor quality or use wireless assisted services which will not function at sea.  Also, once below, the GPS in the tablet may not function as the antenna is obstructed by the deck and the use of internal GPS massively decreases the battery life of the tablet.  A dedicated sensor is therefore by far the best solution and will give much better course and speed readings too.  While some Android tablets can take a USB GPS connection via an OTG cable, trailing a cable to the tablet is messy so a much better solution is a wireless link.  Digital Yacht’s NMEA to wireless products (detailed HERE) are ideal for connecting to existing systems

Nomad – True portability and includes Class B AIS…

A tablet or iPad makes for a great navigation device – lightweight, portable and with a touch screen they are easy to use and there’s a massive selection of charting and navigation apps which generally are a fraction of the cost of sophisticated PC software.  Digital Yacht have now introduced Nomad – a portable Class B AIS transponder (send and receive AIS data) with a wireless interface and portable antenna plus built in GPS.

Next Generation Instrument Solution From Digital Yacht & Seamantec

Here’s a new solution for next generation instrumentation on your boat.  When we designed WindSense, our wireless wind system, we thought most users would utilise mobile devices like iPhones and tablets as a display but it turns out many users also wanted to integrate into a PC system – this makes sense as you can have a large format screen at the chart table or below deck and use mobile devices around the yacht.

Our SmarterTrack chart navigation software provides nice large digital displays of instrument data (as below) so this was one solution but it is primarily designed for chart navigation, AIS, routing and real time nav.  Its worth noting it uses Navionics charting and a unique feature is that traditional chart data stored on Navionics cartridges as used in many chart plotters can be utilised with SmarterTrack too – saving the data on the PC hard drive and minimising charting costs.

SmarterTrack New Instrument Displays

Looking for other solutions we discovered Seamantec and their EDO PC based instrument system.  It can read data from any of Digital Yacht’s wireless NMEA interfaces and also directly from iKommunicate, the NMEA 2000 and 0183 gateway.  It also works with any of our NMEA 0183 sensors.  The display screen is easily configurable for just about any configuration – move the instruments around, choose from analogue or digital format and select “pages” of instrument information to suit exactly what you want and when.  There’s even a mini AIS plotter display

edo nav display

Another neat feature is the Seamantec back ground can be turned off so you’re just left with an instrument display which can be floated over another program – you can see below Seamantec instruments overlaid on top of SmarterTrack.  You can also stack windows side by side just as with any Windows program and take advantage of a big PC screen.

edo instrument layer

Things get really exciting for the racing sailor with Seamantec offering really sophisticated wind displays and the ability to display and calculate boat polar tables like the screen shot below shows

edo wind

Plus there’s logging and recording of NMEA data, voice alarms, a logbook and lots of real time performance analysis.

edo features

So we’re impressed and are offering a bundle of our Aqua Compact Pro PC, iKommunicate and SmaretrTrack plus Seamantec EDO software preinstalled at a special bundle price of $1595.00 – just add monitor, mouse and keyboard and you’ve a powerful navigation and instrument system for any exiting NMEA 0183/2000 network.  Drop us a mail to sales@digitalyacht.co.uk for more information

iKommunicate and the Smart Transducers

Airmar Smart Tdxs

Recently we have seen a trend in customers asking about using smart transducers with our iKommunicate, rather than installing the more traditional; Log, Depth, Wind and navigation instruments.

If you are re-fitting an older boat or doing an install on a new boat, then it is worth considering the cost benefits and simplicity of design that this approach provides. Whether you create an NMEA2000 backbone or simply wire together NMEA0183 cables, having iKommunicate receive all of the transducer data and then distribute this over a wired or wireless Ethernet network, where the data can be displayed on multiple tablets, phones or computers around the boat is very desirable.

One of the most common questions is…”What transducers should I use?” and so we thought we would tackle this question in this article.

When it comes to transducers, the leading player by a mile, is Airmar the US company that manufacture transducers for pretty much all of the big players in marine electronics. As a result, their product catalogue is massive and finding the right model and part number can be pretty daunting and time consuming, so we have tried to highlight the ideal transducers in their range for using with iKommunicate and listed the Gemeco Part Numbers (SKUs) who are Airmar’s US distributor and whose website is very informative.

The obvious “through the hull” Speed and Depth transducer for most yachts and powerboats, would be the DST800. Described as a “Triducer” as it has a Speed, Depth and Temperature sensor, the DST800 is fully retractable for cleaning, with an integral valve that significantly reduces water ingress. It is available in Plastic, Bronze or Stainless Steel, with both NMEA0183 or NMEA2000 versions.

The NMEA0183 version, which can be used on 12v or 24v systems, comes with 10m of cable, terminated in bare wires and you simply add an S to the end of the part number for this version i.e. DST800PV-S.

The NMEA2000 version, powered from the NMEA2000 network, comes with 6m of cable, terminated in the “standard” male NMEA2000 connector (same one as iKommunicate) and for this version you simply add N2 to the part number i.e. DST800PV-N2.

Gemeco SKU Description
DST800PV-S NMEA0183 – 235kHz Smart Triducer – Plastic
DST800BV-S NMEA0183 – 235kHz Smart Triducer – Bronze
DST800SV-S NMEA0183 – 235kHz Smart Triducer – Stainless
DST800PV-N2 NMEA 2000 – 235kHz Smart Triducer – Plastic
DST800BV-N2 NMEA 2000 – 235kHz Smart Triducer – Bronze
DST800SV-N2 NMEA 2000 – 235kHz Smart Triducer – Stainless

So with the DST800, you get Speed (through the water), Depth and water temperature, plus as a bonus a distance log as well, which just leaves the Wind to worry about.

With the Wind transducer Airmar really “threw away the rule book” for designing Mast Head Units by removing all moving parts and using ultrasonics to measure wind angle and speed. Although not ideal for every type of boat, the 120WX and 220WX Weatherstation® instruments are really good bits of kit which not only measure the wind, but also air pressure and air temperature and in the case of the 220WX, with integral GPS and Compass sensors, even your position, heading, rate of turn and attitude (pitch and roll).

Above is an image of the 220WX which is physically identical to the 120WX.

Both units have NMEA0183 and NMEA2000 built-in, so no different versions to worry about, you simply order either a WS-120WX or WS-220WX and specify the type and length of cable you need;

Gemeco SKU Description
WS-C10 NMEA0183 – 10m
WS-C25 NMEA0183 – 25m
WS2-C06 NMEA2000 – 6m
WS2-C10 NMEA2000 – 10m (Terminated)
WS2-C30 NMEA2000 – 30m (Terminated)

There are other lengths available but we have listed the most popular for Yachts and Power Boats. The two NMEA2000 cables that have (Terminated) after them, include the NMEA2000 termination resistor and must be mounted at the end of the NMEA2000 network.

Should your budget not stretch to an ultrasonic wind transducer or you prefer a more traditional mast head unit, then our own WND100 wind transducer which comes with a 20m NMEA0183 cable is well worth considering, perhaps coupled with our HSC100 smart heading sensor and GPS150 Dualnav position sensor both of which have NMEA0 183 outputs to connect to one of the three NMEA0183 inputs on iKommunicate.

So you have your iKommunicate and smart transducer setup, but what options are there for displaying the data? Well you have plenty of PC Navigation packages; Nobeltec, Rosepoint, Fugawi, Seapro, MaxSea, SmarterTrack, etc. and then Apps like NMEA Remote, iSailor, iNavX, iRegatta, SailRacer, TimeZero, Imray etc are perfect for running on your Apple iPhone/iPad or Android phone/tablet in the cockpit. If you want a dedicated display then perhaps a single graphical display from Garmin, Raymarine, Simrad, etc. or a mast display from NASA or Race Geek would give you a permanent cockpit display without breaking the bank.

Finally with iKommunicate you also have the option of running the new Signal K web apps in your browser so any mobile wireless device can display the data on a modern web browser, even a Kindle !

 

WindSense – New Wireless Wind System

WindSense is a new wireless wind system designed to allow iPads, tablets, SmartPhones and PCs to display accurate apparent wind speed and direction.  It features a high quality, precision mast head sensor with 20m cable that connects to a below decks interface unit providing a wifi and NMEA 0183 wired connection.  Existing NMEA compatible sensors can also be connected to the NMEA input to allow the wireless network to share other available on board instrument data.  It’s compatible with a wide range of apps for iOS and android.  The built in wifi will typically footprint a GRP boat up to 30mwindsense-montage-white-back-ground

It has been attractively priced and positioned as a low cost replacement or addition to any marine electronics system but offers significantly enhanced accuracy, reliability and functionality with easy interfacing enabling a tablet to become a complete instrument display with other connected sensors.  There are many vessels equipped with just a speed and depth system who require wind data too and also many older wind systems requiring replacement where customers do not want the substantial cost of a totally new instrument package.  Depending upon the app utilised, true wind information, VMG and other sailing performance parameters may also be calculated.

Key features:

  • Stand alone or networkable (via NMEA 0183) wind system with precision mast head unit
  • Wired connection with super-thin cable from MHU to below deck interface with wireless WiFi and wired NMEA connections
  • Ultra tough IgildurTM mast head unit bearings for exceptional life and corrosion resistance
  • Full range of apps for iOS & Android plus compatible with multiple PC and MAC apps
  • Support for up to 7 WiFi connected devices – use multiple smart phones, iPads or tablets as a display at the helm, chart table or on deck
  • NMEA 0183 output ($MWV)
  • NMEA 0183 (4800 or 38400 baud) input with multiplex facility for WiFi connection
  • WiFi can be standalone or joined to existing network
  • Minimal power consumption
  • Optional NMEA 2000 interface (available late 2016)

Installation is easy with an ultra thin mash head unit cable with removable connector which plugs directly into the interface unit.

windsense-installation

Its then just a matter of connecting power and any other NMEA interface connections you require.

WindSense is compatible with a wide variety of new and existing apps and charting programs with instrument displays.  Both TCP/IP and UDP connections are supported.  There are also free apps from Digital Yacht plus use popular, low cost apps from many 3rd party developers too.  Apps can also calculate true wind information, VMG and other performance sailing data like polars and laylines for racing.
