Is the ""new" ITU Channel Plan implemented in Norway. The Q is that I can read the channel management (Plan) should be in force by 2017-01-01, but implementation date for the hardware onboard (VHF channels with the half (12,5) bandwith channels are posponed to 2024 for ships. (Region three will have the channels for analog audio).

only GNSS signal , no INS during Kalman filtering?

What are the chances of R-Mode along the Norwegian coast, especially on the west coast?

Thanks

How is the situation with patents?

Which station distances are required to achieve good positioning accuracies that meets the IMO requirements?

Thanks.
