Reprogram AIS transponder with new MMSI ProAIS

Why do you need an MMSI for AIS?

All AIS equipment has to be programmed with the accurate MMSI (Maritime Mobile Service Identity) which is the unique identifier that Maritime Authorities worldwide award to each vessel that requires it, be it for regulatory requirement or voluntary request.

In the case of AIS class B equipment, many yachts already have an MMSI because it is needed to get the Call sign for the VHF radio.
