Saab R6 NAV DGNSS System Add-On Kit For Combined R6 AIS-NAV System (7001 000-735)

Saab R6 NAV DGNSS System Add-On Kit For Combined R6 AIS-NAV System (7001 000-735)

Saab’s broader R6 NAV navigation suite is positioned as a “next-generation” maritime navigation system built to exceed IMO and classification expectations, emphasizing integrity protection (including resistance to interference) and a modular architecture intended to be easy to upgrade.

Design and Features

Add-On Kit Concept and Combined AIS-NAV Architecture

A key design theme of the R6 ecosystem is bridge consolidation: the R6 NAV system can share the CDU with the R6 Supreme AIS/VDES transponder, reducing panel space, cabling complexity, and installation cost versus separate displays.

In that combined context, the 7001 000-735 add-on kit provides the DGNSS navigation components and supporting items needed to enable DGNSS functionality alongside a combined AIS-NAV setup.

What’s Included in the 7001 000-735 Add-On Kit

Public distributor listings for 7001 000-735 commonly describe the kit contents as including:

• R5 NAV DGNSS MkIII Sensor with integrated junction box (listed with P/N 7000 118-911)

• Ethernet cable, 5 m (sensor to CDU) (P/N 7000 000-525)

• MGL-5 DGNSS antenna (excluding antenna cable) (P/N 7000 000-555)

• R6 Supreme document media (often listed as a document CD)

• R6 NAV document set

(Exact packaging and documentation formats can vary by supplier and revision, but the above bundle reflects the most commonly published kit breakdown.)

Integrity Protection and Interference Resilience

Saab markets R6 NAV with a strong emphasis on integrity and resilience against modern threats such as GNSS jamming and spoofing. The R6 NAV suite is described as incorporating built-in anti-jamming and anti-spoofing technology, combining filtering and algorithms to detect and suppress interference.

Technology and Specifications

GNSS and DGNSS Capabilities

The R6 NAV GNSS and NAV DGNSS configurations are described as supporting multiple satellite constellations, including GPS, GLONASS, Galileo, BeiDou, NavIC, and QZSS, and using an 800+ channel receiver to improve satellite coverage in challenging environments.

For the DGNSS variant, Saab describes a built-in beacon receiver for differential corrections and integrity information from ground reference stations operating in the ~300 kHz radio-navigation band, with stated ranges up to 250 km, following the IALA standard.

Accuracy Context (as Published for the R6 NAV Family)

Saab’s R6 NAV brochure provides a comparative accuracy overview across configurations. It cites (among other values) approximate performance figures such as:

• Uncorrected: ~1.2 m RMS (67%) / 2.5 m (2DRMS 95%)

• With SBAS (GNSS): ~0.3 m / 0.6 m

• With DGNSS + IALA Beacon: ~0.3 m / 0.6 m

(These values are presented as family-level configuration performance indicators, not installation-specific guarantees.)

CDU (Control and Display Unit)

The shared R6 CDU is described as a sunlight-readable 7-inch capacitive touch display with a 1024×600 resolution and a modern user interface, supporting bridge-friendly operation (including dimming interfaces for central bridge equipment).

Interfaces and Approvals (Family-Level)

Published technical specification excerpts for the R6 NAV brochure include interface support such as IEC 61162-1/2 inputs/outputs and dual IEC 61162-450 Ethernet (RJ45) networking, as well as GNSS/DGNSS approvals references (e.g., IEC 61108-1 and 61108-4) and differential modes including SBAS, IALA Beacon, and RTCM-104.

Applications and Use Cases

SOLAS/IMO Bridge Navigation and Redundancy Planning

Saab positions the R6 NAV line as compliant with IMO safe navigation requirements and suitable for vessels needing robust positioning and integrity monitoring as part of bridge redundancy strategies.

Operations in Interference-Prone Regions

Because the R6 NAV family explicitly targets jamming/spoofing threats, the DGNSS add-on is relevant for operators working in areas where GNSS reliability can be degraded and where integrity monitoring and correction inputs improve operational confidence.

Workboat, Offshore, Dredging, and Special-Purpose Vessels

Saab’s R6 NAV suite is presented as adaptable across segments—cargo and special-purpose operations (e.g., maintenance, dredging, icebreaking, offshore)—with upgrade paths into higher-precision configurations (such as L-band/RTK-enabled variants) where required.

Advantages / Benefits

1) DGNSS Corrections and Integrity via IALA Beacon

The DGNSS approach adds beacon-based corrections and integrity information from shore reference stations, improving accuracy and confidence relative to uncorrected GNSS in many operational contexts.

2) Reduced Bridge Clutter Through a Shared CDU

For combined AIS-NAV deployments, sharing the CDU can reduce the number of separate displays and simplify installation planning—an advantage on space-constrained bridges and retrofit projects.

3) Upgrade-Friendly Modular Architecture

Saab highlights modularity, interoperability, and upgradability in the R6 NAV design, supporting staged upgrades (for example, from GNSS to DGNSS, or toward higher-precision correction services).

4) Interference Awareness and Integrity Protection

Anti-jamming and anti-spoofing features are positioned as core strengths of the R6 NAV family, aimed at maintaining usable navigation outputs under adverse RF conditions.

FAQ Section

What is the Saab R6 NAV DGNSS System Add-On Kit (7001 000-735)?
