INTRODUCTION

OneFix is Digital Yacht’s newly introduced hi-performance GNSS (global navigation satellite system) sensor. Using multiple satellite networks and new dual band technology, it’s been designed to offer super-accurate positioning (typically better than 1m) and importantly has robust anti-spoofing algorithms built in for more reliable navigation. It can also fit to just about any navigation system (including legacy units) plus connect to iPads and tablets and the latest multi-function NMEA 2000 compatible displays. OneFix promises to bring highly accurate, more reliable navigation to any boater.

You may be familiar with the term GPS but GNSS is the more formal name for all the different satellite networks including Glonass, Galileo, Beidou and NavIC that can now also be used for positioning. Most modern marine electronic products can process signals from some of these networks and automatically compute which to utilise to give you the best accuracy.

Another major development in GNSS over the last year has been the ongoing deployment of multi band GNSS. Signals from some satellite networks are now transmitted on L1 and L5 bands and by utilising a sophisticated dual band GNSS, you’ll benefit from better accuracies and a more reliable fix in harsh conditions. Most traditional GPS’s, MFD’s and plotters just use L1 frequencies so can’t benefit from this latest technology.

KEY FEATURES

GPS, Galileo, Beidou and NavIC constellations

OneFix incorporates a dual band (L1 and L5) processor and works with GPS, Galileo, NavIC and Beidou to calculate a fix. Glonass (the Russian based system) is available as an option with a 2nd active antenna making for a very advanced system.

It goes a step further too by using an advanced algorithm to compare position fixes across all networks and frequencies to minimise spoofing and positional inaccuracies.

The result is a highly reliable position fix which offers typically sub 1m accuracy.

Data Logging, Marks & Tracks

OneFix built-in web interface also incorporates data logging and event marking capabilities so key points of a voyage (or even fishing hotspots) can be logged to internal memory. You can download event markers and track log files in GPX and KML formats for easy overlay on Google Maps and charts.

OneFix also supports dual external switch inputs and an “Add Mark” function in the web interface for precise event marking. For advanced analysis, full NMEA 2000 raw data logging is also available.

MOB Functionality & NMEA 2000 Alerts

OneFix can generate industry-standard alerts on the NMEA 2000 bus, enabling “pop-up” notifications on compatible MFDs. When paired with the NavAlarm sounder, it provides an ultra-loud audible alarm to ensure critical warnings are never missed. OneFix generates alerts for position inaccuracy, positioning spoofing or errors, offering enhanced safety and reliability on the water.

OneFix also supports a simple switch input for an MOB, such as Digital Yacht’s MOB input panel, and will generate a synthetic AIS MOB message on the NMEA 2000 network. By pressing the button on the Digital Yacht MOB panel, OneFix will generate NMEA 2000 MOB (man overboard) alerts.

STL Capability

OneFix also has an input for alternative positioning systems such as STL from Iridium. These use triangulation from substitute satellite networks to provide an alternative albeit less accurate position fix (approx. 50m) but have the advantage of a more powerful signal and alternative frequency outside of traditional GNSS constellations.

OneFix can accept data from these systems via NMEA 0183 and switch between networks allowing for a flexible multi-input, hub-based solution.

EASY CONFIGURATION

Accessing OneFix web interface is very simple. Simply use any phone, PC, Mac or tablet to logon to the built-in web interface and no internet connection is required.

Simply open your web browser (Google Chrome, Safari, Mozilla, etc.), enter the OneFix‘s IP address (which is always 192.168.1.1) and you can access the built-in web interface.

Through the interface, you can access advanced NMEA 2000 network diagnostics, offering features such as a detailed device list and PGN displays to simplify the handling of complex interfacing issues. It also enables users to conveniently select sources for NMEA 2000 multiplexed data, ensuring greater flexibility and control over network management.

Sales FAQs

What makes OneFix different from a regular GPS antenna?

−

Traditional GPS receivers on your boat only use single-band GPS (usually L1). OneFix uses dual-band L1/L5 GNSS reception and multiple constellations (including GPS, Galileo, Beidou, and NavIC).

This gives improved accuracy and reliability, especially in difficult conditions.

What is the purpose of OneFix?

−

OneFix is a high-precision positioning sensor designed to deliver extremely accurate position fixes—typically better than 1 meter. Its primary purpose is to replace or enhance a standard GPS on board, providing sailors with more accurate and reliable navigation data.

Simply put, OneFix ensures you always know your boat’s exact position.

What is GNSS spoofing and how does OneFix protect against it?

−

GNSS spoofing is when fake satellite signals trick a GPS into showing the wrong position.

OneFix protects you by using multi-constellation, dual-band GNSS technology to cross-check signals and detect inconsistencies. If suspicious data is detected, it can generate alerts on your network.

This helps detect and reduce false or manipulated signals, increasing navigation safety and reliability.

What systems does OneFix connect to?

−

The OneFix sensor supports NMEA 2000 for modern marine networks, NMEA 0183 for legacy systems, and WiFi for wireless connection to mobile devices and navigation apps.

OneFix will act as the main GNSS source of your navigation system.

Does OneFix record position data and track history? What can it be used for?

−

Yes. It includes built-in data logging and event-marking features.

Your logged position data and tracks can be used to review voyages, analyse performance, document routes, mark fishing spots, or share and export navigation history for planning and record-keeping.

The stored tracks can be exported in GPX and KML formats for use in mapping tools like Google Maps.

Can OneFix work with tablets and apps?

−

Yes. OneFix has a password-protected WiFi interface that lets you wirelessly send GPS/GNSS data to charting apps on tablets, phones and PCs.

Does OneFix provide alerts or safety features?

−

OneFix generate alerts on the NMEA 2000 network for issues such as spoofing or positioning errors, keeping you informed you of potential problems.

You can also fit a external switch input for MOB alerts. When paired with a compatible input panel, pressing the MOB button will generate an AIS MOB message on the NMEA 2000 network.
