By magic, see https://www.sonardyne.com/saab-seaeye-selects-sonardyne-acoustics-for-sabertooth-hybrid-vehicle/ for navigation, control, reporting and position updating. I'm not sure if they're using seabed transponders or surface DGPS sonobuoys or if it's all done from onboard the survey vessel. What does Howard G think? DaveP
