Expand description

Classical (Keplerian) orbital elements in the Vallado convention.

Angles are radians. semi_latus_rectum is the primary size element used by coe2rv so the representation stays well defined for parabolic orbits, where the semi-major axis is infinite.

Fields§

§p: f64

Semi-latus rectum p = h^2 / mu (km).

§a: f64

Semi-major axis a (km). f64::INFINITY for a parabolic orbit (ecc == 1).

§ecc: f64

Eccentricity (dimensionless).

§incl: f64

Inclination in [0, pi] (rad).

§raan: f64

Right ascension of the ascending node in [0, 2*pi) (rad). Undefined (f64::NAN) for equatorial orbits.

§argp: f64

Argument of perigee in [0, 2*pi) (rad). Undefined (f64::NAN) for circular orbits.

§nu: f64

True anomaly in [0, 2*pi) (rad). Undefined (f64::NAN) for circular orbits.

§arglat: f64

Argument of latitude u = argp + nu in [0, 2*pi) (rad). Defined for circular inclined orbits, f64::NAN otherwise.

§truelon: f64

True longitude in [0, 2*pi) (rad). Defined for circular equatorial orbits, f64::NAN otherwise.

§lonper: f64

Longitude of perigee in [0, 2*pi) (rad). Defined for elliptical equatorial orbits, f64::NAN otherwise.

§orbit_type: OrbitType

Geometric classification of the orbit.

Implementations§

Source §

impl ClassicalElements

Source

pub fn new(p: f64, ecc: f64, incl: f64, raan: f64, argp: f64, nu: f64) -> Self

Build a non-degenerate (elliptical inclined) element set from the six primary elements, leaving the auxiliary special-case angles undefined.

This is the convenience constructor for ordinary orbits fed to coe2rv. For circular or equatorial orbits, populate the relevant auxiliary angle and orbit_type directly, or obtain the element set from rv2coe.

p is the semi-latus rectum (km); the semi-major axis is derived as p / (1 - ecc^2).
