Key features

GPS combined with GLONASS, GALILEO and BeiDou operation
Class-leading GNSS/DGNSS performance
Dual 61162-450 networks interfaces for easy integration and redundancy
Dual-use CDU can combine functionality with R6 Supreme AIS/VDES system


Class-leading Performance

Saab’s IMO-compliant navigation systems have been the top choice for professional mariners for almost two decades. The newly type approved R6 NAV, with its proven navigation sensors, is a reliable, flexible, high performing system distinguished by unique features not available in any other system on the market.

Ease of Use

The R6 NAV is self-monitoring and extremely user friendly. It utilizes a highly versatile CDU (Control and Display Unit) and, with options of sensor configurations and antennas, it represents one of the most flexible systems on the market. The R6 NAV is intuitive and easy to operate and designed to be a tool for daily work. Its CDU features a fast modern graphical user interface with a sunlight-readable 7-inch touch display providing accurate colours at any viewing angle. The display has a resolution of 1024x600 pixels in more than 16M colours and features an interface for central bridge equipment dimming.

All information is easy to access through a GUI implementation that reminds of a modern smartphone.

Multi-purpose display

The R6 CDU shares its display with our type approved R6 Supreme AIS/VDES transponder to minimize the number of screens on the bridge and lower the cost for equipment and installation.

Future Proof

The R6 NAV system incorporates the new Bridge Alarm Management (BAM) standard as well as dual LAN interfaces (IEC 61162-450) for efficient network integration into bridge systems.

Simple installation

The R6 NAV system can easily be integrated with other onboard systems such as ECDIS, radar or other display solutions, using traditional NMEA serial communication or network interface. Dual network interfaces in both the sensor and CDU make it simple to install on redundant bridge networks. 

High Performance

R6 NAV provides outstanding position performance in GNSS, DGNSS and RTK mode. It provides access to centimeter-level navigation with RTK data from either external input or L-Band satellite, offering unparalleled performance in the familiar R6 NAV format.

The R6 NAV system is offered in the following configurations:

• R6 NAV GNSS System
• R6 NAV DGNSS System
• R6 NAV PRO System
• R6 NAV PRO RTK System


• Market leading GNSS/DGNSS performance
• Dual 61162-450 networks interfaces for easy integration and redundancy
• Dual-use CDU combines functionality with R6 Supreme AIS/VDES system

• 1PPS timing output port
• CDU with waterproof front for exposed panel mount installations
• Up to 4000 waypoints and 128 routes with maximum 128 waypoints per route
• Integrity monitoring by RAIM and Heartbeat

Did you know...

… what DGNSS stands for? How many satellite systems are supported by R6 NAV? Here are some interesting facts about global positioning.

  • DGNSS stands for Differential Global Navigation Satellite Systems and is an enhancement to GNSS which provides improved location accuracy (down to a few centimeters)
  • Saab’s R6 NAV supports four independent GNSS constellations for improved resilience and flexibility: GPS, GLONASS, Beidou and GALILEO.
  • The vast majority of Saab’s navigation systems are provided to the end customers with the aid of our global distribution and service network.
