Additional information


SAILOR 60 GX is the smallest, lightest and most advanced antenna for the new Inmarsat Fleet Xpress maritime broadband service. Its unique composite/aluminium design keeps weight down while the well-proven SAILOR VSAT technology streamlines the deployment process and maximises operational uptime.

Though SAILOR 60 GX is a super light antenna, it has the ruggedness and reliability required of a professional maritime stabilised antenna system. Additionally, the low weight and compact form factor make it possible for smaller vessels to benefit from VSAT connectivity, when before it may not have been an option due to space available or difficulties and costs associated with the installation of larger, heavier antennas.

A simple revolution in VSAT deployment SAILOR 60 GX is delivered ready to install, with the included SAILOR GX Modem Unit (GMU) and SAILOR Antenna Control Unit (ACU) ensuring quality and reliability throughout the system. Installation is easy, thanks to a wealth of features and design details unique to the SAILOR VSAT technology platform. For instance, it features a single cable between antenna and below deck equipment for RF, power and data, while Automatic Azimuth Calibration and Automatic Cable Calibration enable unique ‘one touch commissioning’. It also features Dynamic Motor Brakes inside the
antenna, removing the requirement for mechanical brake straps whilst ensuring
the antenna is kept in balance in no-power situations, at sea or during transport.
