The electronically steered array  antenna is the only commercially available product in the aviation industry capable of operations with LEO and GEO satellites

Intelsat, operator of one of the world’s largest integrated satellite and terrestrial networks and leading provider of inflight connectivity, announced the successful completion of inflight testing of its new electronically steered array (ESA) antenna. This antenna enables global streaming-fast Wi-Fi service and is available to airlines around the world.

Intelsat’s ESA is the only commercially available antenna in the  aviation industry that can operate between low Earth orbit satellites and geostationary satellites. Announced in June 2022, the new antenna has been accumulating flight hours with Ball, Stellar Blu Solutions, Intelsat and OneWeb engineers validating antenna and network performance.

In early 2023, Intelsat successfully demonstrated the new system to global airlines on the company’s  Bombardier CRJ-700 regional jet outfitted with the new antenna and inflight Wi-Fi system. With peak inflight download speeds exceeding 275Mbps, airline customers were able to participate in live virtual meetings, stream media and stay connected without interruptions.

By using the Intelsat and OneWeb satellite networks together, Intelsat can offer the benefits of LEO’s low latency along with the redundancy GEO provides to address network hotspots that LEO networks on their own cannot address. Whether aircraft are flying polar regions or over the most populated cities in the world, the ESA antenna will offer seamless coverage from takeoff to touchdown.

At just 90 pounds and with no moving parts, the new antenna stands just 3.5 inches tall on the top of the aircraft. The terminal’s low profile has the lowest drag of any product Intelsat has ever offered, reducing CO2 emissions for airlines.

“After installing the system in December, we’ve been hard at work perfecting this new technology and have taken some of the world’s leading airlines for test flights. An antenna without moving parts, that is much smaller than its predecessors, enables airlines to compete in the marketplace, delight their guests and have confidence that Intelsat’s multi-orbit antenna will provide the best performing inflight connectivity experience in the market,” said Jeff Sare, president of Intelsat Commercial Aviation.

Alaska Airlines recently announced plans to use Intelsat’s ESA terminal and IFC services aboard its fleet of Embraer regional jet fleet. Intelsat has supplemental-type certificate programs underway for a wide range of aircraft and expects to begin delivering and installing shipsets in early 2024.
