GPS antennas

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.

NMEA 0183, 2000 & Wi-Fi Interfaces

OneFix has also been designed to connect to older systems via legacy NMEA 0183 as well as more modern systems with NMEA 2000.

Thanks to its password protected Wi-Fi interface, OneFix provides wireless NMEA 2000 data output for charting apps such as Navionics, TimeZero, AquaMaps, Navimetrix and hundreds more. It multiplexes NMEA 2000 AIS, wind, depth, compass, and speed data to the GNSS navigation output, transforming a Tablet, PC, Smartphone or iPad into a full-function, high-precision navigation device with L1+L5 capability.

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.

The GPS-500 is a GPS antenna intended for use with Navico AIS transceivers and VHF systems. It comes with a 10 meter cable with an SMA connector.

GPS - GLONASS antenna designed specifically for marine conditions. It combines a powerful GPS antenna and a 24dB low noise amplifier (@5V DC) in a waterproof antenna. You can connect the NAV-6 GPS/GLONASS receiver as an external antenna in addition to the built-in antenna to ensure the best signal. The NAV-6 also works with most common AIS receivers/transmitters with a TNC connector.

The antenna comes with a cover bracket, mounting kit, 10m RG-58 antenna cable with TNC connectors. The antenna has standard 1" x 14 threads for mounting on a pole.

Garmin GPS antenna GA38

This rugged external antenna is designed for use with the GLONASS system/satellite constellation as well as standard GPS. The antenna is housed in a recessed, waterproof housing and offers three easy mounting options: mast mount, surface mount or under-deck mount (under the fiberglass deck).

External GPS/GLONASS antennas offer more flexibility and installation options, as well as the ability to improve GPS/GLONASS signal reception for products with built-in GPS/GLONASS antennas.
