Connection to the internet is available from all Heincke networks. Depending on region, availability and actual throughput the ship's command can select one of several mobile or satellite based internet links.
A bandwidth measurement prioritizes traffic for essential services.

Low Earth Orbit (LEO) satellite networks Oneweb and Starlink
Low earth orbit satellite communication networks allow high bandwidths at much lower latency than VSAT.
Currently antennas and data volume packages for Eutelsat Oneweb and Starlink are available on board.
Due to the quick consumation of the data volumes certain limits on bandwidth and priotization of services are applied by the bandwidth management system.
Leased Line (VSAT)
The transmission service is enabled via the geostationary satellite Telstar 12 in KU-band. Its orbit position is 15° west. It operates within the European coverage zone (see figure).
Two antennas are installed to guarantee all time connection with no shadowing by ship's mast. Only one of both antennas is activly transmitting at a time.
The maximum throughput is highly dependent on satellite's elevation (perfect > 10°), ship's position and weather conditions.
