Orbital Compute Simulator
Everyone in orbital compute is selling a dream. We sell the math.
Open-source. 222 tests. Honest numbers. Run it yourself.
Explore the Simulator
Interactive tools for designing and analyzing orbital compute constellations.
Interactive Dashboard
Configure constellation parameters and run simulations. View fleet statistics, per-satellite data, and timeline visualizations.
3D Globe View
Three.js visualization with satellite orbits, ground stations, inter-satellite links, and real-time animation controls.
Cost Analysis
Interactive cost calculator comparing orbital compute to cloud providers. CAPEX/OPEX breakdown and sensitivity analysis.
API Documentation
REST API endpoints for programmatic access to simulation, scheduling, fleet status, and cost modeling.
What It Models
End-to-end simulation of a space-based compute constellation.
Orbital Mechanics
Circular orbit propagation with configurable altitude and inclination. Computes period, ground track, eclipse transitions, and satellite-to-satellite visibility.
Power System
Solar panel generation during sunlit arcs, battery charge/discharge modeling during eclipse. Tracks state-of-charge and compute availability.
Thermal Management
Steady-state thermal model accounting for solar input, Earth IR, internal heat generation from GPUs, and radiator performance.
Job Scheduling
Greedy and priority-based schedulers that assign compute jobs across the constellation, respecting power constraints and satellite availability windows.
Inter-Satellite Links
Optical ISL modeling between satellites. Computes link budgets, data routing, and latency for distributed compute across the constellation.
Radiation Environment
South Atlantic Anomaly and Van Allen belt exposure modeling. Predicts single-event upsets and cumulative dose for GPU lifetime estimation.
