Elodin is building the Flight Software Development Platform; we are building the aerospace industry's equivalent to gaming's Unreal Engine, creating a single vertically integrated platform for flight software design, testing, deployment, and operation. We aim to disrupt the standard industry practice of siloed teams for simulation, guidance & control systems, and embedded flight software. We deliver a platform that provides a foundation for seamless software-in-the-loop (SITL) and hardware-in-the-loop (HITL) testing shared across all the disciplines of an aerospace software engineering team.
