VSAT Antenna
Vsat models are designed to transmit and receive Internet, Voip, Fax, E-Mail, Weather Info, High Broadband Data, A/V conferencing, Virtual Private Networks (VPNs), and database backup.
Nautisat Vsat Models guarantee an excellent tracking performance and allows to use the maximum receive and trasmit power.
Vsat is perfect solution for all range of vessel, from ocean going vessels to small yacth, for Oil and Gas platform or Cruise and Cargo Ships, that require “always-on” broadband satellite communications.
The models start from 60 cm of dish to 360 cm, and are configured with Ku-Band only version, in combined Ku-Band/C-Band or in C-Band only.
Nautisat Vsat antenna systems designed specifically for maritime use, and is stabilized to withstand extreme marine environments.

Main Features of all VSAT models are:
Maximum transceiver efficiency with the class M Eutelsat certified prime focus RNFeed optics
Thanks to the proprietary RNFeed technology Nautisat antenna systems ensure great efficiency with high gain and extremely low sidelobes, it permits an high trasmission power with bucs up to 40W.
Rugged, accessible and transparent to radio frequency radomes
Nautisat antenna radomes are built with a “sandwich” stucture of fiberglass and airex®, they are characterized by a really low attenuation level (0.2 dB), an excellent focal precision and great toughness. Every radome is also equipped with an inspection hatch that allows direct access to the inner equipment and makes easy every operation of maintenance and control.
CNC Machined Aluminium and Stainless Steel modular stucture
Almost every mechanical component in a Nutisat marine satellite system is made of aluminium alloy or stainless steel CNC machined from solid, it ensures the maximum mechanical precision and grants to the system the maximum pointing and tracking reliability other than a rugged construction and an excellent resistance to the marine environment.
3 axis stabilization system with indipendent skew
On Nautisat systems stabilization is performed with respect to the dish frame, and in conjunction with the use of coaxial absolute optical encoders, it ensures precise and direct movements from any antenna posing. Steptrack cycle is performed regardless of ship’s geographical position and satellite elevation outsmarting any rough parametric step system. The indipendent Skew Axis with a range of +-175° acts in TVRO models rotating the LNB whereas in VSAT models the whole ANTENNA-FEED-WAVEGUIDE PLUMBING-BUC group is turned. This solution grants to transreceiver antennas a constant radiation pattern and the waveguide transmission lines eliminate any signal loss caused, in other systems, by cables or rotary joints.
Extra wide pointing range with elevation spacing from -30 to +120 degrees and tilt from -30 to +30 degrees
thanks to it’s mechanical architecture Nautisat antenna systems allow a perfect pointing from the poles to the equator with wide compensation margins over ship’s roll and pitch movements.
Automatic satellite pointing and identification
Every Nautisat satellite antenna embed in their powerful control unit a real time satellite recognition system, it ensures a stable link with the transponder and the possibility automatically regulate the uplink transmission.
Extreme component standardization and maintenance simplicity
Every Nautisat System has been designed to reduce the components number to a minimum, creating functional blocks and assemblies to minimize the number of spare parts. Every component, of mechanic or electronic nature, can be swapped over the three axes and through antennas of different model and size allowing even large fleets to navigate safely with few spares. The balanced construction and the open component location make maintenance and repair easy and accessible to all, even if not specialized personnel.
Maximum system integrability
Every ACU implements a communication port through socket server and could be easily integrated with any existent hardware or software ,on board or remotely, that might interact or take control over the antenna system. Nautisat products are ready to operate solo or as part of big and complex systems.
Remote control interface through LAN or over internet
Every ACU embeds a web server that makes possible, with any java enabled browser, to control antennas easily through LAN or over Internet. This particular characteristic makes real scenarios like: remote control, assistance and fleet monitoring.
Extreme easy to install and operate
due to its sofisticate pointing system and to Nautisat proprietary software all the operations needed to install an antenna are reduced to the bare installation trims, that are set by a fully automated procedure. Just a few minutes go by from the antenna deployment to a fully functional system.
The antenna operation is easy and intuitive thanks to the color graphic GUI and to the 4.3″ touch screen of antenna control units.
