FAQ

Frequently Asked Questions

Maritime VSAT (Very Small Aperture Terminal) is satellite broadband connectivity delivered to vessels through a stabilised antenna installed onboard. It provides voice, data and internet services for vessels operating beyond the reach of terrestrial networks.

A stabilised maritime antenna keeps a continuous link with a satellite while the vessel moves. Traffic passes from the onboard terminal to the satellite, down to a teleport or gateway, and then into the internet, cloud platforms or a shore-based operations centre.

Traditional maritime VSAT typically uses GEO satellites with established, broad coverage and managed service options. Starlink is a LEO service focused on lower-latency, high-throughput broadband. Many maritime organizations combine both within a hybrid architecture rather than choosing one.

Depending on the service architecture, bandwidth and coverage, maritime VSAT can support business and operational applications such as enterprise systems, reporting, cloud access and remote monitoring.

Yes. Crew internet, messaging, voice and video calling can be supported alongside operational traffic, usually separated and managed through onboard network policies and traffic management.

Hybrid maritime connectivity combines more than one connectivity technology — for example GEO VSAT, LEO broadband, mobile satellite services and nearshore 4G/5G — behind a maritime network gateway that routes traffic according to availability and application requirements.

Yes. GEO and LEO services can operate together, with the gateway selecting or balancing paths so that operations continue if one path degrades or becomes unavailable.

Iridium is commonly used as a resilient, low-bandwidth backup path for voice, messaging, tracking and essential communications when primary broadband links are unavailable.

Selection depends on vessel type, operating regions, bandwidth and application requirements, number of users, operational criticality, redundancy expectations and the wider IT environment onboard.

Yes. QSAT works with maritime organizations to assess requirements, design an appropriate connectivity architecture, support deployment and integrate satellite services with the wider network environment.
