Operator Agent

The RotaStellar Operator Agent is a lightweight runtime that executes compute workloads on satellites. It uses a pull-based protocol designed for intermittent connectivity — agents operate autonomously and sync with Mission Control during contact windows.
The Operator Agent is open source. See the GitHub repository for the Rust SDK.

​
Architecture

The agent runs on the satellite (or in simulation on a development machine). It communicates exclusively with the Console API — there is no direct connection to the CAE planner.

​
How It Works

  1. Poll — Agent checks for pending workloads during contact windows
  2. Execute — Agent runs workload steps locally on the satellite
  3. Report — Agent streams execution events back to Console
  4. Telemetry — Agent sends periodic health/status heartbeats
The protocol is pull-based by design. Satellites have intermittent ground station contact windows — typically a few minutes per orbit. The agent polls when connectivity is available, executes autonomously, and reports results on the next pass.

Deployment Modes

​
Event Types

The agent uses the same event format as the CAE simulator. Events track the full lifecycle of a workload execution:
