Saab R5 Supreme NAV MkII is Saab's R5-generation marine navigation system, designed to provide reliable position, time, speed, course, and navigational data for marine vessels. The system uses the R5 PRO Navigation Sensor combined with R5 Control and Display Unit – CDU, offering an intuitive operating interface, a large color touchscreen display, and flexible integration capabilities with other marine systems.

The device is suitable for commercial vessels, cargo ships, passenger ships, offshore vessels, service vessels, military vessels, and cockpit systems requiring a highly reliable, easily configurable, and scalable GNSS/DGNSS navigation device.

7-inch color touchscreen, intuitive interface

R5 Control and Display Unit – CDU is equipped with a high-contrast color touchscreen display 7 inches, supporting control via touch or keyboard. The intuitive graphical interface allows operators to easily monitor position data, routes, sensor status, and related alerts.

The R5 CDU also supports Route Navigation, route logging to SD card, combined operation with Navigation & AIS MKDWAASSlave/Redant, port AIS Pilot integration and port USB service port for technical maintenance.

The R5 Navigation Sensor supports GPS, GLONASS, BeiDou, and Galileo

The standard version of the R5 PRO Navigation Sensor supports positioning with GPS combined with GLONASS, BeiDou, and Galileo, which improves satellite reception and position stability in various operating areas.

The device has self-monitoring capabilities, supporting Receiver Autonomous Integrity Monitoring – RAIM to warn when position accuracy falls below user-defined limits. This is a crucial feature for maritime navigation systems, especially when position data is supplied to ECDIS, AIS, radar, VDR, or other navigation systems.

8 output ports, 5 input ports and dual Ethernet

The R5 Navigation Sensor has 8 output portsand in appropriate configurations. These technologies help improve the quality of positioning data when the operating area has corresponding augmented signal support.5 input ports, can be configured for serial data or digital I/O as needed for installation. The product sheet also states that each output terminal can be configured according to IEC 61162-1/2 or digital pulse form such as speed log pulse/event marker; input terminals can be configured according to IEC 61162-1/2 or digital switch such as ALR Ack/MOB Button.

Additionally, the system has dual 1 Gbps network ports, 1PPS timing output, an integrated web server for configuration when operating as a black-box and an integrated junction box, reducing installation complexity on board.

Integrated IALA Beacon Receiver and DGNSS antenna

The R5 Navigation Sensor has the option of Integrated IALA Beacon Receiver, supporting the reception of DGNSS correction signals from beacons when configured appropriately. The system is compatible with MGA-3, MGL-5 or A43 DGNSS antenna antennas depending on standard or PRO configuration.

For vessels requiring more precise positioning data than standalone GPS, the DGNSS/IALA Beacon option enhances reliability for professional navigation applications.

Upgradeable to R5 NAV PRO
