Submodules

opengnc.interfaces.gmat.gmat_interface module

GMAT Python API Integration for high-fidelity truth propagation.

class opengnc.interfaces.gmat.gmat_interface.GMATInterface

Bases: ExternalPropagator

Standardized interface for the NASA GMAT Python API. Used for truth propagation and mission analysis.

connect(**kwargs: Any) → bool

Initialize GMAT engine.

disconnect() → None

Release GMAT resources.

propagate(initial_state: ndarray, start_jd: float, duration_sec: float, step_sec: float) → Dict[str, ndarray]

Run high-fidelity propagation using GMAT.

Returns:

‘times’ and ‘states’ arrays.

Return type:

Dict[str, np.ndarray]

setup_force_model(gravity_deg: int = 20, drag: bool = True) → None

Configure GMAT force model.
