RockFLEET Assured Configuration

Configuration​

The RockFLEET Assured system is supplied pre-configured for rapid installation and operation. If required parameters within the ADU can be changed locally using our BLE based mobile APP or remotely using our Cloudloop platform.

Detailed Configuration of the PRO-APNT

APNT feed to Chart Plotter​

Connecting the RockBLOCK Pro APNT to the ADU and enabling the NMEA sentences will cause the APNT position to show up as a waypoint and the GNSS position as a “ghost“ ship on the chart plotter provided settings are correctly configured.

"Chart":

  • "epeScale": - Affects the size of the second circle, set from 0.5 - 10.0
  • "positionCompareTimer": - Affects the amount of time your gnss position can be outside your epescale * epe, set from 0 - 300
  • "utcDifferenceLimit": - Affects the threshold for checking for time spoofing, set from 2 - 10
  • "utcDifferenceTimer": - Affects the amount of time you're checking for time spoofing before alarming, set from 0 - 300
  • "positionValidityTimer" - Affects the amount of time you're checking for valid GNSS strings before alarming, set from 0 - 300
  • "errorCircle": - Enables or disables the inner circle, set true to enable or false to disable
  • "errorLimitCircle": - Enables or disables the outer circle, set true to enable or false to disable

Configuring the Raymarine AXIOM® 9 Chart plotter.​

Enable alarms by switching AIS safety messages ON. Disable by switching them OFF. See images below.
