Pre-parsed Vallado SGP4 element set.

Use this when the TLE has already been parsed externally (e.g. from an OMM message, JSON catalog, or another system) and you want to feed the element values directly into the SGP4 initializer instead of going through the TLE string parser.

Field units match the Vallado SGP4 reference inputs: angles in degrees, mean motion in revolutions per day, drag term in the dimensionless TLE convention.

Fields

epoch: JulianDate

Epoch as a split Julian date (whole, fraction).

This is format-agnostic and loss-free for the SGP4 initializer: TLE conversion stores the exact split JD produced by Vallado’s days2mdhms/jday path with the legacy 8-decimal fraction rounding, while OMM conversion stores the split JD from its full calendar timestamp directly.

bstar: f64

SGP4 drag term (Vallado B*). Dimensionless TLE convention.

mean_motion_dot: f64

First derivative of mean motion in rev/day². TLE “ndot”.

mean_motion_double_dot: f64

Second derivative of mean motion in rev/day³. TLE “nddot”.

eccentricity: f64

Eccentricity, dimensionless, in [0, 1).

argument_of_perigee_deg: f64

Argument of perigee, degrees.

inclination_deg: f64

Inclination, degrees.

mean_anomaly_deg: f64

Mean anomaly, degrees.

mean_motion_rev_per_day: f64

Mean motion, revolutions per day.

right_ascension_deg: f64

Right ascension of ascending node (RAAN), degrees.

catalog_number: u32

Catalog (NORAD) number for this object. Used only for diagnostic reporting inside SGP4 - propagation results do not depend on it. Pass 0 if unknown.

Trait Implementations

impl Clone for ElementSet

fn clone(&self) -> ElementSet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ElementSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ElementSet

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ElementSet

fn eq(&self, other: &ElementSet) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ElementSet

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
