Satellite Connectivity Solution STC Advanced by Astronics

The FAA has accepted a Supplemental Type Certification (STC) project for an advanced satellite connectivity solution put forth by Astronics. The STC would allow the installation of a satellite connectivity solution comprised of a ThinKom Ka2517 phased-array aero satellite antenna, an Astronics’ Dual-Modem ModMan (ADMM) and Astronics’ radome/support structure system, or its “OAE” (Outside Aircraft Equipment).

“We’re looking forward to delivering another STC on time and continuing to support the aviation market with the components for next-generation systems and certifications.”

Michael Kuehn, President of Astronics CSC.

Under the certification, the system will provide next-generation connectivity performance on board Boeing 777-type aircraft. Approval is scheduled for the second quarter of 2024.

ADMM is Astronics’ newest Modem Manager (ModMan), integrating two high-throughput aerospace modems, an application processor, and aircraft IO in a single 4MCU package for operator network flexibility. Astronics’ OAE support structure consists of a radome, a newly designed adapter plate, a skirt, and wiring. ThinKom’s Ka2517 ultra-low-profile antenna delivers exceptional network flexibility and consistent high performance for global inflight broadband. Products have been developed in partnership with Safran Passenger Innovations and support their growing footprint in the IFEC industry.

Satellite Connectivity Solution Comprised of Proven Components

“Astronics has a rich history of aircraft integration and certification. This latest STC project will highlight the team’s industry-leading capabilities in in-flight connectivity system certifications,” said Michael Kuehn, President of Astronics CSC, a wholly owned subsidiary of Astronics. “We’re looking forward to delivering another STC on time and continuing to support the aviation market with the components for next-generation systems and certifications.”

ThinKom’s field-proven, patented VICTS phased-array technology boasts more than 33 million hours of accrued operation and a mean time between failure (MTBF) exceeding 100,000 hours. The antenna also supports multi-orbit operations, enabling the next generation of inflight connectivity once certified and installed on the 777.

“We are excited to partner with Astronics to deliver this best-in-class offering for another family of aircraft for ThinKom’s antenna technology," said ThinKom CTO and Chairman Bill Milroy. "Combined with Astronics Dual-Modem ModMan, we are poised to deliver a solution to meet airlines’ needs today and well into the future.”
