Bases: object

Properties of one orbit.

Parameters

  • height (float) – Satellite height (in m)

  • lat (numpy.ndarray) – Latitudes (in degrees)

  • lon (numpy.ndarray) – Longitudes (in degrees)

  • pass_time (np.ndarray) – Start date of half-orbits.

  • time (np.ndarray) – Date of the positions (in seconds).

  • x_al (np.ndarray) – Along track distance

  • curvilinear_distance (float) – Distance covered by the satellite during a complete cycle.

  • shift_time (float) – Time shift to be applied.

  • temporal_overlap (float, optional) – Simulate products overlapping by this amount of time, in seconds, with the previous and next products.
