Zendir

Zendir is a Canberra, Australia software company developing a cloud-based spacecraft digital twin and mission validation platform. The platform enables satellite developers and operators to build simulation environments that mirror their spacecraft's hardware and software — including hardware-in-the-loop (HIL) and software-in-the-loop (SIL) testing configurations — without needing deep simulation engineering expertise. Zendir's drag-and-drop interface lowers the barrier to creating realistic spacecraft simulations for mission planning, fault analysis, operator training, and pre-launch validation.

As the small satellite market grows with operators having limited specialized engineering staff, tools like Zendir that democratize rigorous simulation are increasingly valuable. The company is based in Australia's emerging space ecosystem (Canberra/ACT) and has received support from the Australian Space Agency.
