📣 Firmware Update Release:
Firmware Version v0.23 is now released! Please follow the link here or update via Cloudloop Device Manager.

RockFLEET Assured Configuration

Configuration​

The RockFLEET Assured system is supplied pre-configured for rapid installation and operation. If required, parameters within the Above Deck Unit can be changed locally using the BLE mobile app or remotely using the Cloudloop platform.

info

Note: All units are shipped with nmeaForwardEnabled set to false. This must be set to true using the mobile app or Cloudloop Device Manager (CDM) for Chart Plotter communication to work.

Detailed RockBLOCK Pro A-PNT configuration

A-PNT feed to the Chart Plotter​

Enabling the NMEA sentences from the RockBLOCK Pro A-PNT module within the Above Deck Unit displays the A-PNT position as a waypoint and the GNSS position as a "ghost" vessel on the Chart Plotter when the settings are configured correctly.

JAMMING and SPOOFING detection and display settings.​

These settings enable configuration of the Jamming and Spoofing alarm trigger conditions as well as the displayed graphics. The boundary for spoof detection always scales with the A-PNT Estimated Position Error (EPE) so that changes in the level of this error do not cause false alarms.

Alarm Suppression is ONLY possible by parameter adjustment. It is clear that if false positives are occurring or if the alarm is triggering too often then adjustment of the parameters below can reduce annoyance and tune the sensitivity to an appropriate level.

  • "Chart": Allows positions to be plotted on a compatible Chart Plotter, such as the Raymarine AXIOM® 9.
    • "epeScale": - Multiplier that sets the boundary (second circle) for tripping the SPOOF detection alarm, set from 0.5 - 10.0
    • "positionCompareTimer": - Time the GNSS position needs to be outside the boundary(epescale * epe) before the SPOOF detection alarm is triggered, set from 0 - 300 seconds.
    • "utcDifferenceLimit": - Affects the threshold before time spoof checking starts the timer, set from 2 - 10 seconds
    • "utcDifferenceTimer": - Affects the amount of time the time difference threshold needs to be exceeded before alarming, set from 0 - 300 seconds.
    • "positionValidityTimer": - Affects the amount of time GNSS fixes are INVALID or JAMMED before alarming, set from 0 - 300 seconds.
      "errorCircle": - Enables or disables the display of the A-PNT Estimated Position Error (inner circle), set true to display or false to hide.
      • "errorLimitCircle": - Enables or disables the display of the outer circle, set true to display or false to hide.
    • "testingAllowed": - set true to enable the Connect IoT app to impose GNSS position changes for local test and demonstration purposes. Set false to disable.

Configuring the Raymarine AXIOM® 9 Chart Plotter​

Enable alarms by switching AIS safety messages on. Disable the alarms by switching the messages off. See the images below.

Step 1Step 2
Step 3Step 4

Set time source to RockFLEET Assured. See below.

Step 1Step 2Step 3
Step 4Step 5Step 6

Turn off the Chart Plotter's internal GPS. See below.
