Research

Making compute in orbit feasible.

RotaStellar Research builds the systems and models behind orbital compute - constraint-aware planning, on-satellite execution, and distributed training across Earth and space. We publish what we learn: papers, open models, datasets, and benchmarks.

The planner, in one request

CAE turns a satellite and a workload into a feasible plan - or an explicit reason it can't be done. Hover any field to see what it means.

Constraint-Aware Execution Planning for Hybrid Space-Ground Compute Workloads
A planning system that produces feasible execution plans for hybrid space-ground compute workloads under power, thermal, communication, and compute constraints. Deployed in production as the CAE API.
