ThinKom and Kontron have partnered to develop a multi-modem terminal capable of supporting multiple constellations across multiple orbital planes. The solution combines Kontron’s proven ACE Flight 4783 dual modem MODMAN server with ThinKom’s ThinAir® Ka2517 phased-array satcom antenna to deliver flexibility for aircraft operators and systems integrators.
By partnering with Kontron, this complete system enables airlines and integrators to quickly deploy a network-agnostic solution that offers an array of modem combinations, not only for today, but also for tomorrow.
– Bill Milroy, CTO and Chairman at ThinKom
A key focus of the companies is delivering an open-architecture solution, increasing options for owners. As Tony Squeglia, Business Development Director at Kontron, explains, “Our active involvement in the Seamless Air Alliance, coupled with organizations within the satellite connectivity market, like ThinKom, is paving the way for an open platform approach with future-proof capabilities.”

Kontron’s AF4783 Dual Modem MODMAN combines server hardware and two satellite modems in a compact, ARINC 791/792 4MCU compliant system. The system can be further expanded to add a third modem if desired. This allows an airline to mix-and-match up to three suppliers, without installing additional terminals on the aircraft. Moreover, the ThinAir Ka2517 has proven connectivity across LEO, MEO, and GEO constellations, further increasing airline options.
The companies suggest the system is network agnostic today, while being future-proof for tomorrow.

Given the lack of LEO Ka-band satellites in service today, it is fair to say that the solution is targeting airlines looking for multiple GEO options today. Or it could look to bring O3b’s Ka-band service online, though commercial aerospace does not seem to be a key target market for O3b. LEO services could be added when those constellation(s) become available, assuming the satellite operators are willing to work with outside partners. The two main Ku-band LEO constellations have thus far not certified ThinKom’s ThinAir terminals on their networks.
