Compatible with both geostationary (GEO) and low-Earth orbit (LEO) constellations, ESA delivers reliability and consistency along with low latency so your passengers can text, browse or stream, wherever they’re flying. Redundant GEO capacity makes it ideal for routes over hub cities, while the LEO network offers low latency and polar coverage. And, with speeds up to 275Mbps, passengers have a snappier inflight experience.

Lightweight, Low-profile Design Contributes to Sustainability Goals

Significantly lighter than other antennas in operation and with no moving parts, the ESA antenna stands less than three inches tall. This new antenna design offers the best aerodynamics, reducing fuel burn and lowering CO2 emissions. In fact, we have calculated that ESA can save airlines approximately $40,000 per aircraft annually, that is nearly 200 barrels of oil you will never have to buy – or burn.

Installation Options that Support Your Airline’s Unique Fleet

ESA’s flexible installation options make it the right choice for aircraft of all sizes, from regional jets to widebody aircraft.

Intelsat holds STCs for Embraer ERJ170 and ERJ175, Bombardier CRJ 700 and CRJ 900. An STC is pending for the Airbus A320.

For airlines purchasing new Boeing aircraft delivering in 2026, ESA will be selectable as a linefit option on Boeing B737, B777, B787. A service bulletin will be available for B787 retrofit installations.
