Marine Satellite Communications Systems

Marine satellite communication (SatCom) systems enable reliable voice, data, and internet connectivity across oceans and remote waters. These systems are essential for navigation, safety, operational logistics, and crew welfare—especially where coastal radio or cellular networks fall short.

From broadband internet to point-to-point microwave relays, our SatCom solutions cover a wide range of mission-critical needs for commercial shipping, research vessels, and private yachts. We offer satellite terminals, antennas, and service plans from leading brands including Inmarsat, GlobalStar, KVH, JRC, Skymate, and SeaTel.

A Brief History and the MH370 Example

Inmarsat was established in 1979 to support global maritime communications. Its SatCom network became vital for navigation, safety, and crew communications over vast oceans. In 2014, the disappearance of Malaysia Airlines Flight MH370 highlighted the importance of SatCom data—while the airplane's transponder was disabled, routine satellite "handshakes" (pings) logged by Inmarsat helped investigators reconstruct its flight path using time delay and Doppler-shift analysis (inmarsat.com). The method clarified how long-range SatCom can provide crucial data even when primary systems fail. A detailed non-paywall article is available at BBC News.
