Plot one or more orbit ground tracks on an Earth map.

Parameters:

  • r ((n,3) array_like or list of (n,3)) – GCRF positions [m]. Either a single orbit or a list of orbits.

  • t ((n,) array_like or list of (n,)) – Absolute times matching r.

  • ground_stations ((k,2) array_like, optional) – Rows of (lat_deg, lon_deg).

  • save_path (str, optional) – Save figure path.

  • title (str, optional) – Plot title.

  • show_legend (bool, default True) – Show legend.

  • fontsize (int, default 18) – Base font size.

  • start_end_markers (bool, default True) – Mark orbit start/end points.

  • labels (list of str, optional) – Per-orbit labels.

  • orbit_colors (list, optional) – Per-orbit colors.

  • linestyles (list, optional) – Per-orbit line styles.

  • legend_kwargs (dict, optional) – Extra legend kwargs.

  • central_longitude (float, default 0.0) –

    Center longitude of the displayed map. Examples:

    0 -> Greenwich-centered 180 -> Pacific-centered

  • relabel_xticks (bool, default True) – If True, relabel x ticks into conventional [-180, 180) longitude values.

Returns:
