PRS Sensor Control

Advisory failure simulation for the 24 position reference systems connected to MV NORTHERN AURORA. Every change immediately recalculates confidence, position error, redundancy and DP class — no control authority over the DP system.

DP Normal — Green

DP GREEN — Autopos Active

Bulk control

Online / offline control

Switch a technology family offline to simulate a common-mode failure, or drop individual sensors to rehearse a degraded-reference scenario. With every reference offline the system falls back to the dead-reckoning set & drift model on the PRMS accuracy envelope.
