Alta Data Technologies and Avilution form MOSA avionics partnership

By AI, Created 5:14 PM UTC, May 18, 2026, /AGP/ – Alta Data Technologies and Avilution announced a strategic partnership on May 15, 2026, to combine modular flight software and interface hardware for Modular Open Systems Approach avionics. The companies say the collaboration is meant to cut vendor lock-in, speed modernization, and help defense platforms integrate legacy data links into software-defined systems.

Why it matters: - The partnership targets a major defense aviation problem: how to modernize aircraft without tying upgrades to one vendor’s hardware stack. - The combined approach is designed to support MOSA and SOSA goals, which matter for faster integration, easier upgrades, and lower certification effort. - The agreement could help defense programs move legacy avionics data into higher-speed, software-defined architectures.

What happened: - Avilution, developer of the eXtensible Flight System (XFS), and Alta Data Technologies announced a strategic partnership on May 15, 2026. - The companies are pairing Avilution’s modular software with Alta’s MIL-STD-1553 and ARINC interface products. - The goal is to deliver a flight-ready MOSA solution for aircraft modernization. - The collaboration is aimed at Army aviation and global defense platforms.

The details: - Avilution’s XFS is aligned with the Future Airborne Capability Environment, or FACE, standard. - Alta’s hardware and software development kit, AltaAPI, serves as the connector between XFS and Alta’s interface products. - Alta’s ENET and NLINE appliances and SOSA-aligned XMC cards can be used to integrate XFS into FACE-compliant systems. - XFS uses standalone, safety-critical data microservices that are independent of hardware and operating systems. - XFS is configured through non-executable configuration files rather than manual coding. - Avilution says that approach leaves the core XFS software untouched and preserves its qualification. - Alta’s interface portfolio includes MIL-STD-1553 and ARINC devices, XMC cards for SOSA and MOSA modular systems, and ENET/NLINE appliances for network-centric architectures. - Alta products are used on platforms including the C-130, Black Hawk, and Apache. - The companies provide an example program that maps XFS structures directly to Alta hardware data structures. - The utility is configurable through a simple text file. - The tool supports 1553 and ARINC-429 setups. - The partnership is intended to enable rapid hot-swappable prototyping.

Between the lines: - The deal reflects a broader industry shift away from proprietary avionics integration and toward reusable, software-defined building blocks. - The emphasis on configuration files, microservices, and network nodes suggests the companies want integrators to change mission capability without rewriting core software. - Mark Spencer, founder of Avilution, said Alta’s network-centric ENET products and SOSA-aligned XMCs let XFS treat legacy I/O as a simple network node. - Richard Schuh, CEO of Alta, said the pairing of XFS microservices and Alta appliances helps engineers decouple mission capabilities from rigid hardware.

What’s next: - The companies are positioning the partnership for faster deployment of new capabilities in response to evolving defense requirements. - The example integration program may serve as a practical path for customers building FACE-compliant and MOSA-oriented systems. - The collaboration could expand as defense programs look for more reusable avionics architectures.

The bottom line: - Alta and Avilution are betting that open architecture software plus adaptable interface hardware will make avionics modernization faster, cheaper, and easier to certify.
