RockFLEET Assured

The system uses GNSS whenever the signal is valid and continuously cross-checks the data with Iridium PNT. It detects anomalies such as spoofing or jamming, flags events, and alerts users when issues occur. Even during disruptions, the system continues reporting trusted position data via A-PNT.

RockFLEET Assured can be configured for integration with existing onboard systems using either NMEA 2000 or NMEA 0183 over RS422, depending on the selected build.

For simpler serial integrations, it can feed NMEA 0183 data into a multiplexer alongside other navigational components. For installations requiring cleaner below-deck wiring, longer cable runs, power management, or lightning protection, the optional Power Hub provides a dedicated junction point for connected bridge equipment.

Yes. RockFLEET Assured can be configured as an input to an ECDIS or other onboard system, with interface type chosen before shipping. Units supplied with the optional Raymarine Axiom 9 chartplotter use NMEA 2000, while units intended for integration into a customer’s own system use NMEA 0183 over RS422.

RockFLEET Assured is not an IMO-approved primary navigation source, so it is intended for use as a backup, comparison, alerting, or other non-primary input.

RockFLEET Assured offers an optional Raymarine Axiom 9 chartplotter in two formats: a rugged case version for a complete out-of-the-box setup, or a lower cost version without the case using a wiring harness.

If no chartplotter is purchased, the system can still integrate with existing onboard equipment. Depending on the selected build, RockFLEET Assured can output A-PNT and GNSS position data via NMEA 2000 or NMEA 0183 over RS422. Configuration is handled through the Bluetooth app, which also provides a visual map of both GNSS and A-PNT positions.

For more complete bridge integrations, the optional Power Hub provides a below-deck junction point for power, protection, and NMEA connectivity.

Not for every deployment. RockFLEET Assured is designed around a simple above-deck terminal, but the Power Hub is recommended where the vessel needs below-deck power management, lightning protection, longer cable runs, or standard NMEA 2000 / RS422 integration with bridge equipment.

The Power Hub is configured at the factory to match the chosen RockFLEET Assured build option: NMEA 2000 or NMEA 0183 / RS422.

When GNSS/GPS signals are unavailable, vessels can effectively become “blind” from a positioning perspective, with little or no reliable location accuracy available. In these scenarios, A-PNT provides a highly valuable independent positioning capability, typically delivering 25–100 meter accuracy.

While this may not match the precision of GNSS, it represents a dramatic improvement over having no positioning information at all, enabling continued navigation, operational awareness, and resilience in GNSS-denied environments. Performance is generally even better at higher latitudes due to the geometry of the Iridium satellite constellation.

RockFLEET Assured includes configurable geofencing, integrity monitoring, anomaly detection, and real-time alerting. Operators can define reporting schedules, receive notifications when vessel position integrity is compromised, and monitor events from shore.

Yes. RockFLEET Assured creates a verifiable record of vessel positions, integrity events, and system alerts that can support post-incident investigations and operational reporting. For shipowners operating in regions where GNSS interference is a known risk, having an independent source of position data can strengthen evidence trails and demonstrate proactive risk management practices to stakeholders, insurers, and charterers.

Traditional GPS receivers are highly effective under normal conditions but remain vulnerable to jamming and spoofing. RockFLEET Assured adds a trusted, independent layer of position assurance that helps operators verify the integrity of navigation data and identify potential interference events. For shipowners, this means greater confidence in vessel tracking, improved operational resilience, and enhanced protection against emerging maritime security threats that could otherwise disrupt navigation and fleet operations.
