1.1 SAILOR XTR Ka system
The SAILOR XTR Ka is a unique stabilized maritime GX antenna system operating in the Ka-
band (17.7 to 30 GHz). It is used with the Global Xpress service from Inmarsat, delivering
consistent high-performance download speeds of up to 50 Mbps and 5 Mbps over the
uplink. The following figure shows the coverage map of the GX service.
The system requires a single 50 Ohm coaxial cable to provide the antenna (ADU) with both
DC power, data and control information. The radome does not have to be removed neither
before nor after the installation. To protect the ADU the built-in motors act as brakes during
transport and when the ADU is not powered. You can access the SAILOR XTR Ka remotely
and make in-depth performance analysis using the built-in web interface.
