Saab R5 NAV Mk III DGNSS Sensor (7000 118-911)

Saab R5 NAV Mk III DGNSS Sensor (7000 118-911)

The part number 7000 118-911 is publicly associated with the R5 DGNSS Sensor MkIII receiver option in certified navigation system documentation.

In typical deployments, the sensor is paired with a control/display unit (CDU) and an approved antenna solution, and then integrated to ECDIS, radar/ARPA, VDR, conning displays, or an Integrated Bridge System (IBS) via marine data standards (e.g., IEC 61162 / NMEA-style sentences).

Design and Features

Role within a ship’s navigation sensor suite

A DGNSS sensor is a primary upstream source of position and timing information used by bridge electronics to support safe navigation, route monitoring, chart display, and recording systems. In many bridge designs, multiple independent positioning sources are used for redundancy and cross-checking; a DGNSS receiver may be chosen when differential correction capability is desired as part of the vessel’s operating concept.

Mk III sensor hardware family and receiver option

Within the UK marine equipment conformity documentation for Saab’s navigation systems, the R5 DGNSS Sensor MkIII is explicitly listed as receiver option 7000 118-911, associated with underlying hardware identity 7000 118-703 and software families 1.4.x / 1.5.x in the assessed configuration.

Integrated junction box (installation-friendly architecture)

Public system bills of materials for “R5 NAV DGNSS System MkIII” describe the sensor as the R5 NAV DGNSS Sensor with integrated Junction Box (P/N 7000 118-911). This “sensor + junction box” architecture is typically used in marine installations to simplify cabling, service access, and junction/termination management in bridge or equipment-room layouts.

Approved antenna options for DGNSS installations

The same UK conformity documentation lists antenna options for DGNSS systems, including 7000 000-555 / 7000 000-780 as DGNSS antenna options, indicating a standardized antenna ecosystem aligned to the DGNSS receiver option.

Technology and Specifications

Note: Detailed performance figures (e.g., positioning accuracy, update rate, supported constellations/bands, and full output sentence lists) are often distributed through official datasheets and controlled documentation sets. The items below focus on verifiable, publicly visible technical and compliance attributes.

DGNSS capability (concept)

DGNSS refers to GNSS positioning enhanced by differential corrections from external correction sources, used to reduce certain error components and improve reliability in specific operating contexts. The practical improvement realized depends on the correction service, antenna installation, RF environment, and integration design. The R5 NAV Mk III DGNSS sensor is positioned as the DGNSS-capable receiver option in Saab’s certified navigation system family.

Standards and marine environmental testing context

The UK Module B certificate for the R6 navigation system family lists assessed testing standards and bridge interface standards commonly associated with professional marine navigation equipment, including:

• IEC 60945 (marine navigation and radiocommunication equipment—general requirements)

• IEC 61162-1 / IEC 61162-2 / IEC 61162-450 (marine digital interfaces, including Ethernet-based messaging)

• IEC 61108-1 (GNSS receiver equipment performance standard)

• IEC 62288 (presentation of navigation-related information)

• IEC 62923-1 / 62923-2 (Bridge Alert Management testing references)

These references help define the certification and interoperability context in which the R5 DGNSS Sensor MkIII (7000 118-911) is used, especially when installed as part of a system intended for compliance-driven vessel classes.

System-level components commonly shipped with MkIII DGNSS kits

A public “R5 NAV DGNSS System MkIII” listing shows typical inclusions alongside the sensor (7000 118-911), such as a compatible CDU, Ethernet and power cables, a DGNSS antenna option, and documentation media/printed documentation. While these kits are not the sensor itself, they describe how the sensor is commonly delivered and installed in the field.

Multi-constellation positioning context (system family)

A distributor product description for the R5 SUPREME NAV MkIII system family references multi-constellation GNSS operation (e.g., GPS with GLONASS, BeiDou, and Galileo operation) and Bridge Alert Management compatibility testing, reflecting the broader ecosystem in which the DGNSS sensor is deployed.

Applications and Use Cases

SOLAS and compliance-driven vessel environments

The R5 DGNSS Sensor MkIII (7000 118-911) appears as an assessed receiver option within a UK marine equipment conformity framework that references SOLAS carriage and performance requirements for navigation equipment categories. This context is relevant to operators and integrators planning installations where type approvals, certificates, and test standards are required for commissioning, class, or flag-state acceptance.

Integrated Bridge Systems and multi-display distribution

In IBS deployments, one positioning source may feed multiple downstream consumers (ECDIS, radar overlay systems, conning, VDR, bridge alerting subsystems). The presence of IEC 61162-series interface standards in the assessed documentation aligns with the R5/R6 family’s use as a bridge-networked navigation data source.

Coastal, pilotage, and operations benefiting from differential corrections

DGNSS is commonly selected for operations where correction services are available and where the vessel’s operational profile benefits from improved integrity and consistency—such as coastal navigation, port approaches, pilotage support workflows, and navigation system cross-checking (depending on onboard procedures and regulatory requirements). The R5 NAV Mk III DGNSS sensor is the DGNSS-capable receiver option in this family.

Refit and upgrade programs

Fleet operators often replace earlier-generation GNSS/DGNSS sensors during refits to align with support lifecycles, standardized spares, and updated compliance documentation sets. In this setting, the Mk III sensor is treated as a modern receiver option within an approved product ecosystem, rather than a standalone consumer GNSS device.

Advantages / Benefits

Differential correction capability (DGNSS)

Compared with a GNSS-only configuration, the DGNSS sensor is designed to support differential corrections where correction services and installation design allow, potentially improving operational robustness in relevant conditions. (Actual performance depends on correction source, antenna, RF environment, and integration.)

Compliance and interoperability orientation

Because the R5 DGNSS Sensor MkIII (7000 118-911) appears in a conformity-assessed navigation system family with explicit references to IEC marine standards (interfaces, environmental requirements, and GNSS performance), it is suitable for integrators who must document standards alignment during approvals, acceptance testing, or audits.

Standardized antenna ecosystem

The listing of DGNSS antenna options (e.g., 7000 000-555 / 7000 000-780) supports predictable procurement and replacement strategies—important in fleets where antenna failures, cable degradation, or lightning-related issues can drive periodic replacement.

System integration readiness (typical kits)

Public MkIII DGNSS kit BOMs demonstrate that the sensor is commonly delivered as part of a ready-to-install system scope (sensor + CDU + cables + antenna + documentation), reducing integration friction for projects that prefer validated component combinations.
