# orts
orts core — orbital mechanics simulation, force / torque / sensor models,
and a WASM plugin host runtime.
Provides the simulation engine at the heart of the
[orts](https://github.com/sksat/orts) workspace:
- Orbital dynamics (two-body, Brouwer mean-element propagator, TLE/SGP4-equivalent).
- Attitude dynamics and control (reaction wheels, gravity gradient, PD / B-dot).
- Force models: gravity harmonics, drag, SRP, third-body, constant thrust.
- Sensor models: magnetometer, gyroscope, star tracker.
- WebAssembly Component Model plugin runtime (`plugin-wasm` /
`plugin-wasm-async` features), hosting guest controllers via wasmtime.
