Antaris and Infostellar formed a strategic partnership on January 21, 2026 to integrate cloud-native ground services directly into an AI-powered mission planning platform.
The partnership connects Infostellar’s global ground station network with the Antaris software-defined satellite ecosystem to unify fragmented satellite operations.
The integrated Antaris–StellarStation solution enables operators to automate scheduling and execution of ground station passes directly within the Antaris interface.
The partnership’s roadmap includes adding more diverse ground assets to the StellarStation network to provide Antaris users with a resilient and geographically distributed communication framework for high-cadence Earth observation and telecommunications missions.
Linking Infostellar’s hardware-diverse network to the Antaris software stack provides a scalable path for constellation owners to obtain global coverage without building proprietary ground infrastructure.
Antaris’ cloud-based platform uses digital twins and software-defined architectures to simulate and manage satellite missions from design through end-of-life.
The combined Antaris and Infostellar solution is undergoing final validation with initial pilot customers who are using the integrated platform for upcoming small satellite deployments.
Infostellar’s StellarStation is a Ground Segment as a Service (GSaaS) provider that is integrated into the Antaris platform.
