Can anymore more "in the know" explain why an accuracy increase from "several meters" to 1m would decrease the SAR time from 3 hours to 10 minutes in the open ocean? It's not like the precision difference matters here. I could see it helping in the mountains where there's a lot of signal interference so Galileo might provide better real-world accuracy, but this doesn't make sense on the open ocean. There must be some other component to the service that's not being described.
