Saab R6 NAV GNSS System (7001 000-730)

Saab R6 NAV GNSS System (7001 000-730)

Within the R6 NAV lineup, 7001 000-730 represents the GNSS (SBAS-augmented) configuration. Saab positions it as a complete kit delivered with the R6 CDU (Control and Display Unit) and a GNSS antenna, and as an entry point in a modular family that can be upgraded to DGNSS and higher-precision variants when operational needs change.

Design and Features

Modular R6 NAV Architecture

Saab’s R6 NAV family is built around a modular architecture intended to simplify integration and upgrades. The brochure describes the system as easy to upgrade, with interoperability and a flexible architecture for bridge solutions—an approach aimed at long equipment lifecycles and evolving regulatory or operational requirements.

R6 CDU Bridge User Interface

A central feature of the system is the R6 CDU, described as a sunlight-readable 7-inch capacitive touch display with 1024×600 resolution and a modern user interface. The CDU also supports dimming integration for central bridge equipment, reflecting typical bridge usability and night operations requirements.

Multi-Constellation GNSS and SBAS Support

For the GNSS configuration, Saab states that the R6 NAV GNSS uses an 800+ channel multi-GNSS receiver and supports major constellations, including GPS, Galileo, GLONASS, BeiDou, NavIC, and QZSS. The 7001 000-730 variant is described as using SBAS (Satellite-Based Augmentation System) to enhance accuracy and integrity assurance.

Integrity Protection Against Jamming and Spoofing

Saab emphasizes integrity protection in the R6 NAV line, describing built-in anti-jamming and anti-spoofing technology that combines digital filtering and algorithms to detect interference and suppress compromising signals. This is framed as a response to increased maritime GNSS threat environments and the vulnerabilities of older navigation equipment.

Shared CDU with Saab R6 Supreme AIS/VDES

A distinctive integration concept in Saab’s ecosystem is that the R6 NAV system may share the CDU with the R6 Supreme AIS/VDES transponder, potentially saving bridge space and cost in combined installations.

Technology and Specifications

System Variant Definition (7001 000-730)

In Saab’s R6 NAV brochure, 7001 000-730 is explicitly identified as “R6 NAV GNSS”. The brochure describes the configuration as:

• 800+ channel multi-GNSS receiver

• SBAS augmentation (WAAS, EGNOS, MSAS)

• Antenna: MGA-3

• Option for external input from an IALA Beacon receiver (as an input source rather than built-in beacon reception)

Performance Positioning in the R6 NAV Family

Saab’s brochure includes an overview chart that associates the GNSS (SBAS) configuration with improved accuracy versus uncorrected GNSS:

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

• R6 NAV GNSS (SBAS): 0.3 m / 0.6 m

(These are published, configuration-level figures; real-world results depend on antenna placement, local conditions, and interference environment.)

Interfaces and Approvals (Family-Level Specs)

The R6 NAV brochure lists technical specifications that apply across the R6 NAV platform, including:

• IEC 61162-1/2 serial inputs/outputs

• IEC 61162-450 Ethernet (RJ45) networking

• GNSS/DGNSS approvals references IEC 61108-1 and 61108-4

• Supported differential modes listed as SBAS / IALA Beacon / RTCM-104

• Receiver sensitivity −142 dBm and 800+ channels (receiver-level characteristics)

Typical Kit Contents (Commercial Listings)

Public reseller/market listings commonly describe the 7001 000-730 system as a complete package including a navigation sensor (with an integrated junction box), CDU, mounting kit, and antenna. An example listing describes:

• R5 NAV GNSS MkIII Sensor with integrated junction box (7000 118-910)

• R6 SUPREME CDU (7000 123-500) and gimbal mount kit

• Power and Ethernet cabling

• GNSS antenna (commonly listed as MGA-3) and documentation

Applications and Use Cases

SOLAS Bridge Navigation and Compliance-Driven Installations

Saab positions the R6 NAV family as compliant with IMO safe navigation requirements under SOLAS Chapter V, making the R6 NAV GNSS system a fit for vessels requiring bridge-integrated, standards-aligned positioning systems.

General Cargo and Special-Purpose Operations

Saab’s brochure highlights applicability across general cargo and special-purpose operations such as maintenance, dredging, icebreaking, and offshore work, where positioning integrity and continuity are operationally significant.

Modernization and Lifecycle Upgrades

Because R6 NAV is presented as modular and upgradeable, the GNSS SBAS configuration (7001 000-730) is commonly used as:

• A primary GNSS system for vessels that do not require built-in beacon DGNSS

• A modernization step from older GNSS receivers, with an upgrade path to DGNSS/PRO/RTK variants later

Advantages / Benefits

Robust Multi-Constellation Coverage

By supporting multiple GNSS constellations and using an 800+ channel receiver, the system is positioned for strong satellite availability in challenging environments and improved resilience versus single-constellation designs.

SBAS Augmentation for Accuracy and Integrity

SBAS capability (e.g., WAAS/EGNOS/MSAS) provides correction and integrity information, and Saab presents the GNSS SBAS configuration as achieving sub-meter class accuracy in its family overview.

Anti-Jamming and Anti-Spoofing Focus

Saab explicitly markets integrated jamming/spoofing suppression, which is increasingly relevant for maritime operations in areas where GNSS interference is encountered.

Bridge-Friendly Human Interface

The sunlight-readable 7-inch touch CDU with modern UI and bridge dimming interface supports watchstander usability, alarms/awareness workflows, and daily navigation operations.
