:type ephemeris_id: int :type orientation_id: int :type mu_km3_s2: float, optional :type shape: Ellipsoid, optional :rtype: Frame

Fields

ephemeris_id: i32

orientation_id: i32

mu_km3_s2: Option<f64>

Gravity parameter of this frame, only defined on celestial frames

shape: Option<Ellipsoid>

Shape of the geoid of this frame, only defined on geodetic frames

Implementations

impl Frame

pub const fn new(ephemeris_id: i32, orientation_id: i32) -> Frame

Constructs a new frame given its ephemeris and orientations IDs, without defining anything else (so this is not a valid celestial frame, although the data could be populated later).

pub const fn from_ephem_j2000(ephemeris_id: i32) -> Frame
