Three ways to get a vessel connected

Receive-only television, two-way satellite internet, or a line-of-sight microwave link. Most vessels end up with two of the three — and the choice is driven by where the ship works, not by which product is newest.

Satellite TV at Sea (TVRO)

Stabilized TV reception for crew and passengers, from one dish to a multi-cabin system.

TVRO is the system that lets a vessel receive broadcast satellite television while moving. The chain is short and well understood: a stabilized antenna tracks the satellite, an ACU holds the parameters, a receiver selects the transponder, and a distribution layer delivers the picture to cabins or a crew mess.

Typical scope

V Series (2-axis) or X Series (3-axis) stabilized antenna
Basic or Advanced ACU
TVRO receiver and multiswitch
CATV headend or IPTV headend with decoders

VSAT Internet and CCTV Backhaul

Two-way satellite communication for internet, voice, video and remote monitoring offshore.

Where TVRO is receive-only, VSAT is two-way: internet access, voice calls, video, remote assistance and remote diagnostics over a satellite link that works anywhere in the footprint. The catalogue documents the shipborne VSAT route with Ku, Ka and C-band options, mounted on the same stabilized-antenna family used for TV.

Typical scope

Shipborne VSAT antenna (Ka / Ku / C band)
Modem and control panel
4G/5G marine antenna with automatic priority switching
Shore-side monitoring where required

Offshore Microwave Links

High-throughput ship-to-shore and ship-to-ship links without satellite airtime.

A vessel working a fixed area near shore does not always need satellite bandwidth. A tracking 5.x GHz microwave link covers up to 100 km ship-to-shore at 200–300 Mbps, with no recurring airtime charge and lower latency than a satellite hop.
