GPS/GNSS spoofing & jamming protection for merchant vessels
Where GNSS is unreliable, spoofed, or jammed, RockFLEET Assured supports trusted position reporting via Iridium PNT and assured positioning (A-PNT) workflows.
For crews and operators, an optional chart view presents the assured position alongside GNSS position / track with clear integrity status and event logging, helping teams identify anomalies quickly and maintain situational awareness.
Integrity events and alerts can also be logged and shared with shore teams, supporting operational oversight and post incident review when it matters most.
Deploy, monitor, & integrate easily
RockFLEET Assured is designed around a simple above-deck terminal for faster vessel deployment, with setup and status provided through a Bluetooth LE mobile app. For installations that need cleaner bridge integration, the optional Power Hub provides below-deck power management, lightning protection, and standard NMEA connectivity.
RockFLEET Assured supports configurable position reporting, OTA configuration, and geofence-based alerting for operational and security workflows.
For fleet operators and merchant shipping technical teams, RockFLEET Assured connects into Cloudloop Tracking for browser-based fleet views. Cloudloop is also API-first, so you can consume location, integrity status, and events in your own platform via push delivery, including webhooks, MQTT, and cloud destinations, or pull via REST API using a consistent structured JSON format.

Where does RockFLEET Assured Fit?
The solution provides a resilience layer for the bridge or onshore remote fleet monitoring. It is not a SOLAS navigation instrument by design.
- Use for independent comparison alerting on position integrity against GNSS positioning
- Back up reference and situational monitoring
- Trusted reporting and compliance
Designed to support bridge confidence, shore side oversight and incident review.
RockFLEET Assured FAQs
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 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.
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.
