Orbital Runtime
Overview
The Orbital Runtime provides execution primitives designed for the unique constraints of space:Orbit Scheduler
Workload orchestration across Earth and orbital nodes
Adaptive Runtime
Energy and thermal-aware inference execution
Resilient Compute
Fault-tolerant ML for radiation environments
Why a New Runtime?
Standard cloud runtimes assume:| Assumption | Reality in Space |
|---|---|
| Always-on network | Intermittent connectivity |
| Stable power | Variable solar/eclipse cycles |
| Predictable latency | Orbital geometry dependent |
| Reliable hardware | Radiation-induced faults |
Architecture Preview
Your application connects to the RotaStellar Orbital Runtime, which orchestrates workloads across Earth and orbital infrastructure.Orbit Scheduler
Routes jobs to optimal nodes based on latency, energy, and availability
Adaptive Runtime
Adjusts precision, layer execution, and context based on constraints
Resilient Compute
Radiation-tolerant execution with checksums and redundancy
| Node Type | Location | Characteristics |
|---|---|---|
| Earth DC | Terrestrial | High bandwidth, stable power, lowest latency to users |
| LEO Node | 400-600 km orbit | Solar powered, 25ms latency, intermittent ground contact |
| GEO Node | 35,786 km orbit | Continuous coverage, 250ms latency, limited power |
