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.

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.

The throughput of maritime satellite systems is still much lower than what we are used to by land based connections such as LTE or DSL.
Therefore a bandwidth measurement prioritizes traffic for essential services, networks and computers.
The following prioritization classes are defined
...
- Blocking: Some services such as Android/Apple app upgrades , private VPN and security-related protocols are blocked.
