Position Reference Systems on your Vessel

Would like to get a consensus of what types and how many Position Reference Systems you have onboard your vessels. Also please say what type your vessel is. Thanks Everyone.


We have two DPGS, one free signal and then a CNAV 3050 with a subscription service. Our relative is a Cyscan.

sorry, but my position is to deny everything…

If you have any DP1 time after advance class then you will need 240 days of DP time. I am having to 240 day due to the fact I have 116 days on DP1 vessel. Also any DP1 time only counts as half days. If you have a limited certificate already then all you need is 60 days on a DP2 or DP3 class vessel
