BSV Podcast 0150: Antaris

Balerion Principal Aidan Daoussis sits down with Tom Barton, Co-Founder & CEO of Antaris, to discuss software-defined satellite systems. Antaris provides a software- and AI-based platform for designing, simulating, manufacturing, and operating satellite constellations. Its full-mission virtualization tools model spacecraft, ground infrastructure, software, and mission operations before deployment.Timestamped Overview00:00 – Introduction and overview of the Antaris platform01:14 – Barton’s background in open-source software, cloud infrastructure, and Planet Labs04:02 – Founding Antaris to bring software abstraction and interoperability to space systems05:01 – Platform capabilities spanning design, simulation, command and control, and flight software07:03 – Limitations of legacy flight-software architectures and the SatOS approach09:09 – Full-mission virtualization for government agencies and defense primes13:08 – Reducing mission risk, development time, and human operational workload15:13 – Edge AI, onboard processing, and software-defined satellite missions17:14 – Multimodal Earth observation and delivering actionable intelligence18:36 – Driving adoption without displacing incumbent spacecraft systems20:29 – Sovereign space programs and localized satellite manufacturing23:26 – How space software differs from conventional B2B SaaS25:50 – Automated constellation operations and human oversight of exceptions28:48 – Antaris’ defensibility through abstraction, synthetic telemetry, and specialized AI31:18 – Customer demand in Japan and the value of end-to-end simulation33:27 – Venture-capital dynamics and the shift from vertical integration toward interoperability38:17 – Quantum key distribution, optical communications, and future satellite demand44:03 – Common simulation surprises, including power, thermal, and ground-network constraints46:44 – Marquee customer acquisition, future milestones, and Antaris’ multimodal ISR strategy49:40 – Closing takeaway and conclusion This is a public episode.
