Orbit Communication Systems is expanding its partnership with Inmarsat through the development of a terminal for the Ka-band satellite network provider’s Jet Connex in-flight broadband service. Orbit’s AirTRx30 consists of two line replaceable units—a modem manager and a tail-mounted antenna that is compatible with super-midsize and large-cabin business jets.

The AirTRx30 features Orbit aperture designs used by Inmarsat’s government customers and will be interoperable with the new Inmarsat-6 F1 Ka-band satellites, the first of which was launched in December. Inmarsat said other existing onboard Jet Connex equipment also will be compatible with these new satellites.

"Inmarsat has a successful track record of working with Orbit in the government market,” said Inmarsat head of business aviation Kai Tang. “We are delighted to build on this strong foundation and expand our partnership into business aviation.” Tang added that 1,100 customers use Jet Connex.

Israel-based Orbit is moving toward approvals for the AirTRx30. The company is working with OEMs, service providers, and after-market partners to establish distribution, certification, installation, and customer support of the terminal, which will be manufactured at Orbit's Deerfield Beach, Florida facility. Qualified terminals will begin shipping in the first quarter of 2023 or earlier, Orbit said.
