Over complicated?
OK it was only 2 axis station keeping but a certain HMS vessel was automatically station keeping to within a foot or two, in various sea states, 30 years ago.... its kind of important when you are maintaining an umbilical, amongst other things, to keep things very steady at the top.... so whats another degree of freedom between friends?
/mines the one with the 12" data analysis tape from the Station Keeper in its pocket... also a cattle prod in the other to poke the analyst with - she didn't bother checking for PEOT so I had to hand wind it out of the drive at least once.
Biting the hand that feeds IT
