RockFLEET Assured

RockFLEET Assured is a compact, marine-grade smart antenna that delivers trusted position reporting alongside conventional GNSS sources and provides two-way satellite messaging worldwide. It integrates the Iridium Positioning, Navigation and Timing (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 100m 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 IMT. For position and configurable data payloads, including telemetry, status and 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 Over the Air.
• 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 (BLE). Configuration, commissioning and status reporting, including position and message or connection status.
• Simple Installation (all-in-one antenna + up to 100m cable). Single above-deck terminal - no below-deck electronics required unless bridge view is used - with marine cable up to 100m for flexible routing.

The RockFLEET Assured system uses an Above Deck Unit connected by a single cable up to 100m long. Below Deck Unit is the general term for equipment installed below deck. The supplied below-deck equipment depends on the selected bundle:

• Full bundle: a standalone Raymarine AXIOM® 9 Chart Plotter and a Power Hub.
• Rapid Deploy bundle: a Raymarine AXIOM® 9 Chart Plotter fitted inside an Explorer rugged case.
• NMEA 0183 or NMEA 2000 stand-alone bundle: a Power Hub for connection to compatible third-party equipment.

The primary function is to monitor the difference between the A-PNT position and GNSS position. If the GNSS signal is lost or jammed, or appears in another location because it has been spoofed, an alarm is raised.

Alongside the local functionality on board the vessel, both A-PNT and GNSS positions can be monitored in the Cloudloop tracking platform.

The Above Deck Unit is housed in a proven marine enclosure and includes:

• Iridium Certus® IMT communication through a built-in RockBLOCK Pro A-PNT.
• A receiver for Iridium STL® assured positioning solutions.
• A receiver for traditional GNSS PNT solutions.

The Rapid Deploy below-deck equipment is housed in a rugged portable case and includes:

• A Raymarine AXIOM® 9 Chart Plotter that displays the A-PNT position alongside the GNSS position.
• A power supply and communications interface.

Position Display

• Vessel symbol (black dot when stationary) - position provided by A-PNT.
• Green arrow - Position provided by GNSS.
• Inner circle
  • Represents the current Estimated Position Error (EPE) provided by A-PNT. The radius of this circle can range from 25m to 5,000m depending on the quality of the A-PNT 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.
