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’ve calculated that ESA can save airlines approximately $40,000 per aircraft annually, that’s nearly 200 barrels of oil you’ll never have to buy – or burn.
