opengnc.interfaces package

Subpackages

Base classes for external tool interfaces in OpenGNC.

class opengnc.interfaces.base.ExternalPropagator[source]

Abstract base class for external propagators (GMAT, Orekit, etc.).

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

Run propagation in the external tool.

Parameters:

initial_state (np.ndarray) – Initial state [x, y, z, vx, vy, vz] in meters and m/s.
start_jd (float) – Start time in Julian Date.
duration_sec (float) – Propagation duration in seconds.
step_sec (float) – Output time step in seconds.

Returns:

Dictionary containing ‘times’ (Julian Dates) and ‘states’ (nx6 array).

Return type:

Dict[str, np.ndarray]

class opengnc.interfaces.base.ExternalTool[source]

Bases: ABC

Abstract base class for external tool integrations.

abstractmethod connect(**kwargs: Any) → bool[source]: Establish connection or initialize the tool.

abstractmethod disconnect() → None[source]: Clean up resources and disconnect.

Standardized interfaces for external tools (GMAT, Orekit, STK).
