RockFLEET Assured

RockFLEET Assured is a compact, marine-grade smart antenna that delivers trusted position reporting and two way satellite messaging worldwide. It integrates the Iridium PNT module to support assured positioning (A-PNT) workflows and uses Iridium Messaging Transport (IMT) to enable routine position reports. Supplied with a marine-grade cable of up to 100 m length for flexible installation, RockFLEET Assured is available with an optional backup battery to continue tracking and reporting if vessel power is interrupted.

RockFLEET Assured is built on our proven RockBLOCK PRO series

Key Features

• Assured Positioning (A-PNT) via Iridium PNT. Authenticated position source for trusted vessel position reporting in areas where GNSS is unreliable, spoofed or jammed.
• Chart View (bridge situational awareness). Nautical chart display showing assured position alongside GNSS position / track with clear status indicators.
• Integrity Alerts. Configurable alerts and event logs when position integrity is at risk, shown locally and optionally forwarded to shore.
• Two Way Messaging via Iridium Messaging Transport. For position + configurable data payloads (telemetry, status, events).
• Configurable Reporting. Scheduled, event-driven, and exception reporting with intervals from 1/min to 1/hour; reporting profiles and all configuration can be updated OTA.
• Geofencing & Alerting. Entry/exit alerts with rule-based monitoring for security and operational workflows.
• Power Cut Resilience (optional). With backup battery for continued tracking / reporting during vessel power interruption.
• Mobile App (Bluetooth LE). Configuration, commissioning, and status reporting, including position and message / connection status.
• Simple Installation (all-in-one antenna + up to 100 m cable). Single above-deck terminal - no below-deck electronics required unless bridge view is used - with marine cable up to 100 m for flexible routing.

The RockFLEET Assured system comprises Above and Below Deck Units (ADU + BDU) interconnected with a single cable that can be up to 100m in length.

The primary function is to monitor the difference between the Assured A-PNT position and GNSS. If GNSS is lost (i.e Jammed) or appears in another location (i.e. Spoofed) then an alarm is raised.

Together with the localised functionality on board the vessel both A-PNT and GNSS positions can be monitored in our Cloudloop tracking platform.

ADU housed in a proven marine enclosure.

• Iridium Certus® IMT communications via a built in RockBLOCK PRO-APNT.
• Receiver for the Iridium STL® APNT solutions.
• Receiver for traditional GNSS PNT solutions.

BDU housed in a rugged portable case comprising:

• Marine chart plotter to display the APNT position alongside GNSS position.
• Power supply and communications interface.

Position Display

• Vessel symbol (Black dot when stationary) - Position provided by APNT.
• Green arrow - Position provided by GNSS.
• Inner circle
  • Represents the current Estimated Position Error (EPE) provided by APNT. The radius of this circle can range from 25m to 5000m depending on the quality of the APNT signal processing.
• Outer circle
  • Represents the alarm trigger boundary. The radius of this circle will depend on the epeScale setting. When set to 1.0 both circles will align.
  • The alarm will sound if the GNSS position moves outside the outer circle and remains there for a duration greater than the positionCompareTimer setting.
