Paltry PPU position predictor
“The pilot’s PPU was obtaining information from the vessel’s AIS, which was subject to GPS ‘smoothing’. As a result, the predicted vessel positions displayed on the PPU were not accurately reflecting the vessel’s future positions, but the pilot was unaware of this.” Check out this vessel grounding report on The NI’s website: https://www.nautinst.org/resources-page/202332-paltry-ppu-position-predictor.html
