Intelsat, operator of one of the world’s largest integrated satellite and terrestrial networks and leading provider of in-flight connectivity (IFC), has completed a series of historic test flights to the Arctic Circle demonstrating that airlines that require inflight internet connectivity on long-haul flights at extreme northerly latitudes can access low-latency, high-throughput service at any point on their route map.

“Airlines and their passengers have never had access to polar connectivity, but Intelsat made history as the first inflight connectivity provider to provide high-speed internet service above the Arctic Circle,” said Dave Bijur, the company’s senior vice president of Commercial Aviation. “This is an important region for airlines operating intercontinental flights. Thanks to Intelsat’s multi-orbit satellite service and ESA antenna, millions of international passengers flying on polar routes will enjoy reliable, non-stop connectivity from gate to gate.”

The test flights were completed on Intelsat’s test aircraft, a CRJ-700 regional jet equipped with an Electronically Steered Array (ESA) antenna. During the test flights, engineers from Intelsat and Ball Aerospace collected data necessary to understand the ESA’s operations and connections with different satellite orbits at different latitudes:

• On December 17, 2023, Intelsat operated its test aircraft from Seattle, Washington to Anchorage, Alaska. Anchorage is located at roughly 61° north, making it the northernmost city served by major airlines, anywhere on the planet. This flight was operated using Intelsat’s fleet of geostationary (GEO) satellites, proving that high-throughput GEO service is available using Intelsat ESA at all global airline hubs.
• On December 18, 2023, Intelsat operated a roundtrip flight from Anchorage to Utqiagvik, Alaska (formerly Barrow, AK). Utqiagvik is situated at a latitude of 71° north, the same as many polar routes connecting Asia, North America, and Europe. This flight was operated using OneWeb’s fleet of low Earth orbit satellites and demonstrated that high-speed, low latency performance is available even in a challenging geographic region that previously never had inflight internet service.

“The two tests validated the capabilities of Intelsat’s multi-orbit solution for airlines,” said Pat Walsh, senior vice president of Engineering. “As the aircraft traveled due north from Anchorage into the Arctic Circle, we seamlessly connected to the OneWeb low-earth orbit constellation delivering 150 megabits per second inflight and on the ground in Alaska. In addition, near the polar region, Intelsat’s GEO operations exceeded expectations, delivering a reliable, high-speed connection all the way to Anchorage.”

Commenting on the test flight, Ben Griffin, VP of Mobility at Eutelsat OneWeb said, “We congratulate Intelsat on this milestone moment, made possible by OneWeb’s low Earth orbit constellation. This continuous connectivity across all routes and latitudes is a game changer for international airlines flying between East and West across the polar region. This historic flight validates the 5C’s of connectivity that together OneWeb and Intelsat can deliver to our airline customer namely – coverage, capacity, connection, consistency, and community.”
