SkyLink Citadel from Blue Sky Network is a resilient anti-piracy
solution. Easy to install and operate, Citadel offers voice and data
connectivity to the outside world, when needed.

With the flick of a switch, a SOS message is transmitted off the ship
and battery backup ensures communications, even if the external
power is shut down.

Leveraging the Iridium Certus® satellite network, SkyLink Citadel
provides two HD voice lines and the ability to send and receive
messages and emails from a laptop. The mid-band data rate offers
88 kbps download and 22 kbps upload.
