While the majority of Satellite data communication links still operate in Ku-Band there has been a growing adoption of Ka-Band satellites as well in the maritime world.
While the original concerns of rain fade and pointing accuracy did prevent the fast adoption of Ka-Band in maritime satellite communication it has now evolved and several Operators now offer Ka-Band VSAT service.
Ka-Band (27-40 GHz)
The two most prominent offerings are Inmarsat Fleet Xpress which includes Fleetbroadband backup to cover for the gaps in the global Ka-Band coverage, and Telenor Thor 7 service which covers Iceland to the Middle East and offers speeds up to 40Mbps down.
There are several Antenna Manufacturers offering antennas fit for either platforms. Models are availbale from Cobham Sailor, Intellian and KNS (expected).
