Ka2517 Phased-Array Aero Antenna Demonstrates Seamless Beam-to-Beam and Inter-Constellation Handover with SES’ MEO and GEO Satellites

HAWTHORNE, Calif. – Oct. 23, 2019 – ThinKom Solutions, Inc. has completed a series of very successful in-flight connectivity tests of its Ka-band antenna on SES’ O3b medium-Earth orbit (MEO) and geostationary (GEO) satellites.

The tests provided the first live demonstration of airborne communication with the O3b MEO satellites and included seamless handovers between MEO and GEO satellites during flight.

The in-flight demos used the Thales FlytLIVE connectivity network and incorporated the Hughes JUPITER™ ModMan integrated to the ThinKom Ka2517 antenna.

The flights took place Sept. 17-18 over South Florida and the Caribbean Sea, using a commercially available ThinKom Ka2517 phased-array airborne antenna mounted on a Gulfstream G-III test aircraft. With the Hughes JUPITER Aeronautical system and ModMan, the antenna demonstrated the ability to achieve high data throughput rates while seamlessly switching among successive O3b MEO satellites, as well as transfers between O3b and SES’ GEO constellations.

The Ka2517 achieved downlink error-free data throughput rates in excess of 265Mbps, with beam switching speeds of less than one second, while automatically resolving adjacent satellite interference (ASI) issues.

“This is the first in-flight demonstration of an aeronautical antenna communicating across a MEO-GEO hybrid satellite network. The Ka2517 with the JUPITER ModMan met or exceeded all test parameters for spectral efficiency, data throughput, beam agility, switching speeds, ASI mitigation, low-angle performance and inter-constellation roaming,” said ThinKom Chief Technology Officer Bill Milroy.

“The demonstration further establishes that ThinKom has the only proven ‘no compromise‘ antenna solutions that can support seamless global satellite communication in the air with automatic roaming among GEO, LEO and MEO constellations,” Milroy added.

Based on ThinKom’s patented phased-array VICTS technology, the Ka2517 is an airborne antenna designed to communicate through satellites in low, medium and geostationary orbits. The low-profile antenna radome provides near-zero aeronautical drag in flight and supports global coverage including polar and equatorial latitudes. The field-proven Ka2517 is currently in commercial production, and units are in operational service on U.S. government aircraft.

“The test by ThinKom underscores the effectiveness of the Hughes JUPITER System for both MEO and GEO connectivity, and, when combined with a high-quality antenna such as the ThinKom Ka2517, to deliver superior spectral efficiency, link availability and performance,” said Reza Rasoulian, Vice President, Hughes Network Systems, LLC (HUGHES).

SES’ high-throughput O3b MEO constellation is the only operationally and commercially proven non-geostationary satellite orbit (NGSO) broadband constellation today. The constellation has positively impacted millions of people with low-latency, high-performance data connectivity services and has enabled SES Networks, SES’ business unit focused on data solutions, to offer more capacity, enhanced coverage, increased efficiencies and greater flexibility to its customers.

“These successful demo tests are raising the bar for in-flight connectivity and the connected passenger experience. The seamless integration of our MEO and GEO satellite networks will provide our customers with unprecedented redundancy, higher connectivity speeds and a whole new level of operational models,” said Elias Zaccack, Executive Vice President, Global Sales, at SES Networks. “We’re very excited to have achieved this milestone together with our long-term partner Thales, as this is yet another example of how our mutual collaboration continues to bring innovative connectivity solutions with unmatched performance.”

“These in-flight tests performed together with SES, ThinKom and Hughes are an outstanding demonstration of the seamless connectivity through MEO and GEO satellite systems. Thales Alenia Space was particularly pleased to participate in this worldwide first, using the O3b satellite constellation we manufactured for SES,” said Pascal Homsy, Executive Vice President, Telecommunications Business Line, Thales Alenia Space.
