ThinKom provides phased array antennas to GDC Technics


ThinKom Solutions is supplying its ThinAir Ka2517 aero satellite antennas to GDC Technics to support Inmarsat’s GX terminal and associated broadband services in flight. According to ThinKom, Inmarsat’s flat Ka-band phased array antenna was selected after more than 18 months of collaboration and field testing by ThinKom and GDC based on reliability and performance criteria.

The Ka2517 will serve as the assistive technology supporting Inmarsat’s GFC Aviation Broadband Satellite In-flight Connectivity Systems (IFC), including the new North American IFC service GX + announced earlier this year by Inmarsat and Hughes Network Systems.

The Ka2517 is based on ThinKom’s VICTS antenna technology which, according to the company, has accumulated more than 18 million hours of operation in more than 1,550 commercial aircraft with a mean downtime (MTBF) of over 100,000 hours.

According to ThinKom, the VICTS antenna offers spectral efficiency and high throughput as well as uninterrupted pole-to-pole connectivity at extremely high and low elevation angles. The antenna’s low power consumption leads to very little heat generation in the radome and enables uninterrupted operation from gate to gate, even at high ambient temperatures with full solar radiation.

“The Ka2517 antenna fully complies with the new regulatory requirements, including WRC-19 EISM and ITU Article 22, and ensures that 5G terrestrial cellular networks or GEO satellites are not disturbed when used in NGSO networks,” said Bill Milroy, Chairman and Chief Technology Officer of ThinKom Solutions. “It also provides the switching speed and flexibility to work seamlessly with new multilayer GEO, HEO and NGSO satellite networks.”

GDC’s next generation IFC terminals with Ka2517 antennas have received an additional type certificate (STC) for Boeing B737-700 aircraft. GDC has planned a full range of STCs for the Airbus A320 Family, other B737 models, and Boeing B787 and B777 aircraft in early 2021.
