SDK-compliant module type
Atmosphere And Force Models
Force model modules provide environmental terms that propagators and estimators can call without embedding app-specific physics in OrbPro2.
What it can do
Compute density, drag, solar radiation pressure, gravity harmonics, third-body acceleration, and space-weather-dependent terms for high-fidelity propagation and OD.

Contract shape
Inputs describe epoch, spacecraft state, attitude or projected area, environment configuration, and requested terms. Outputs are accelerations, density, partials, quality flags, and model provenance.
Authoring checklist
- Declare all frames, units, celestial constants, and time scales.
- Separate deterministic model configuration from live data inputs.
- Validate against published model cases or trusted operational tools.
- Return warnings when extrapolating outside authoritative data ranges.
