Viasat Marine Access System

We can take care of the details so you can concentrate on running your vessel.

Viasat Marine Access System (MAS) offers an on-board network management solution to enable high-speed internet and is purpose built for maritime. MAS offers flexibility to deploy simple to complex networks for a wide range of vessel types. It seamlessly aggregates multiple connections, provides cybersecurity, and determines priority access to those on-board. Viasat offers two options, MAS 500 and MAS 1000 to meet your network management needs.
