OneFix
Hi-Precision GNSS
Positioning Sensor
Using multiple satellite networks and new dual band technology, it’s been designed to offer super-accurate positioning and importantly has robust anti-spoofing algorithms built in for more reliable navigation.
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.
OneFix has also been designed to connect to older systems via legacy NMEA 0183 as well as more modern systems with NMEA 2000. OneFix also has a password protected Wi-Fi interface.
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 Deep Sea’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.
SPECIFICATIONS
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.
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.
Yes. OneFix has a password-protected WiFi interface that lets you wirelessly send GPS/GNSS data to charting apps on tablets, phones and PCs.
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.
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.
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.
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.
