Constellation Space

Constellation Space Corp (ConstellationOS) is the ML-native operations platform for satellite fleets, founded in 2025 in Seattle and backed by Y Combinator. Operators connect ground telemetry through one API and one schema, run machine-learning link forecasts on live fleet context (SNR and link fade, traffic, weather, jamming, and conjunction), and act under operator policy with automated routing, stream isolation, and failover. The ConstellationOS HTTP API exposes fleet topology reads, telemetry ingestion, and predictions, secured with scoped bearer tokens, alongside a web console, a fleet agent CLI, and a public status page.

Constellation Space publishes 3 APIs on the APIs.io network: Predictions API, Telemetry API, and Topology API. Tagged areas include Company, Satellites, Space, Telemetry, and Machine Learning.

Constellation Space’s developer surface includes documentation, API reference, getting-started guide, signup flow, pricing, support, authentication, and 23 more developer resources.
