Asynchronics

Asynchronics develops simulation software and digital twins that help satellite teams design, integrate, and verify spacecraft systems more efficiently. We build NeXosim, a high-performance simulator, and NeXosim.io, a marketplace for digital models of COTS spacecraft hardware. Our solutions enable realistic SIL/HIL testing and mission-level scenarios without relying solely on physical hardware. We also deliver custom model development and integration services, including commercial tooling such as GUI and interfaces to existing engineering workflows.
