Quick Facts
About Antaris
Antaris is a Sunnyvale, California software company founded in 2020 that provides an end-to-end cloud platform for designing, building, simulating, and operating satellites. The platform's TrueSim digital twin environment enables mission architects to test satellite software and hardware-in-the-loop before launch, and the cloud-based operations layer provides autonomous command and control post-launch.
Antaris targets the growing market of corporate and government customers who want to build and operate a satellite but lack deep spacecraft engineering expertise — the platform abstracts away much of the ground segment and operations complexity. The company's approach is inspired by the AWS model applied to space: standardized infrastructure that lets a wider range of customers build satellite applications without starting from scratch. Antaris has partnerships with satellite bus manufacturers and integrators.
