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

Its always good to have a few weeks at boat shows and listen to customer questions. Differences between models always crop up as Digital Yacht have a big selection of Class B AIS transponders on offer. We hope this document helps you decide which is best for your installation. All units share a common technology platform so will give excellent performance and importantly have future proof SatTrak technology built in.
All AIS transponders require their own dedicate internal GPS (you can’t use a NMEA feed from an existing GPS). The AIT1500 series has a super sensitive internal antenna which cuts down on the need for another external antenna. It will work well even below decks on GRP vessels but steel or wood will attenuate the signal too much. The AIT1500 series is therefore great for RIBs, Center Consoles and GRP sail boats. With many larger sail boats now fitting multi function displays in the cockpit, it can be unobtrusively installed in a location adjacent to the MFD and the same for flybridge motor boats.
The AIT1500 comes in two versions – one for NMEA 0183 based systems and one for NMEA 2000 systems. The later is also self powered from the NMEA 2000 bus so installation really is plug ‘n play. Both models have a USB interface for PC & MAC for programming and PC plotting.
Has dual NMEA 0183 and NMEA 2000 interfaces plus USB and ships with a dedicated external GPS antenna. Its a great solution for wooden and steel vessels that require an external GPS antenna
Appropriately called “Nucleus” as it forms a hub in any marine electronics system. It features our patented ZeroLoss VHF antenna splitter technology so the main VHF antenna can be shared with VHF and AIS which means no need for another VHF antenna and sophisticated connectivity including not just NMEA 0183 and NMEA 2000 but also WiFi for iPad and tablet interfacing. Up to 7 wifi connected devices can be attached and neat NMEA interfacing allows instrument, AIS and GPS data to be used by hundreds of compatible apps. There’s also a FM radio antenna outlet.
Here’s a 5 minute guide on Youtube and of course we’re standing by on email and phone to answer any queries. Digital Yacht – for your biggest and best choice in Class B AIS.
Digital Yacht have just released a new AIS Class B transponder intended specifically for easy installation on small yachts, motor boats and RIBs. It’s designed to simply plug into an existing NMEA 2000 network to provide compatible plotters and instruments with AIS data. As a transponder, it also sends vessel data to other AIS users. Class B units require their own GPS in order to ensure they transmit accurate data and this normally means another antenna outside the boat. The AIT1500N2K has a built in, highly sensitive GPS so it can work below decks on GRP boats cutting down on antenna clutter. All that’s required to complete operation is connection to a VHF antenna or suitable AIS-VHF antenna splitter such as the Digital Yacht SPL2000.
There’s a USB interface for programming and also for use with PC/MAC based charting applications. Digital Yacht also have an optional WiFi adaptor for the NMEA 2000 backbone to allow data transfer to a tablet, smart phone or iPad – details HERE
“Many boaters see the huge benefits of AIS and want to embrace the technology but are put off by a difficult and costly installation. The AIT1500N2K couldn’t be easier to fit – it even takes power from the boat’s NMEA 2000 network. This standard is now embraced on just about every modern chart plotter or instrument system to allow plug ‘n play interfacing” commented Paul Sumpner, CTO of Digital Yacht.
The AIT1500N2K is available now and will be on display at the London Boat Show 2016 Stand C021
Digital Yacht products integrate easily into superyacht systems. This new guide for installers and dealers shows some typical systems ranging from AIS tender tracking thorough to iPad navigation, marine PCs and on board NMEA networking – all great, value adding solutions. Come and see these latest systems at the Miami Boat Show Digital Yacht Booth 2509 12-16 Feb 2015

Classic Yacht “Misty” has undergone a $0.5m transformation by A&R Way Boat Builders and the results are stunning. Classic Boat magazine have a fantastic feature on the restoration in this month’s issue. She was originally constructed back in 1964 by Lallows. She’s 37ft 6in (11.5m) LOA – a couple of feet longer than Cheverton’s 1958-designed Danegeld that won everything in sight a year after. She was in fact designed to beat Danegeld, but ended up as test and demo boat for her original owners – Ratsey and Lapthorn Sailmakers.
But even a classic yacht deserves some hi-tech navigation and she’s equipped with a Digital Yacht AIT2000 Class B transponder and SPL2000 VHF-AIS antenna splitter to minimise antenna clutter. This is integrated with a NavLink NMEA to WiFi server so data can be displayed on iPads and tablets through the vessel or in the cockpit leaving a beautiful classic finish but boasting the best in navigation! Find out more about the NavLink server from HERE
We’ve decided to publish our dealer training presentations on line so that the whole boating community can benefit. Paul Sumpner, Digital Yacht’s CTO, was at the CA Clase distributor training event this week and presented a great overview on some of our core technologies including:
AIS – Hints and tips on transponder operation, programming and antenna selection
Wireless NMEA – differences between TCP/IP and UDP connections and app integration
GPS antennas and interfacing
Wireless internet and routers including common problems with accessing marina hotspots
Most importantly he covered lots of installation issues with hints and tips and important product selection advice. Of course, reading a presentation on line is not as good as hearing the real thing so if you do have questions, feel free to contact us.
