}

Parsed TLE orbital elements in canonical astrodynamic units.

Angles are degrees, mean motion is revolutions/day and its derivatives rev/day^2 and rev/day^3, BSTAR drag is 1/earth-radii, and the epoch is the calendar epoch_year plus the one-based fractional epoch_day_of_year.

Fields

catalog_number: String

Catalog number as it appeared at the format boundary.

Numeric TLE fields keep their five-character representation (for example, "00005"), and Alpha-5 fields keep their letter-plus-four-digit representation (for example, "A0000"). Use decode_catalog_number to obtain the numeric catalog id.

Implementations

impl TleElements

pub fn to_element_set(&self) -> Result<ElementSet, TleError>

Convert these parsed TLE elements into the canonical SGP4 ElementSet IR consumed by crate::astro::sgp4::Satellite::from_elements.

This is the single TLE-to-IR mapping: the public TLE entry point parses a TLE to TleElements, converts here, and feeds the result into the same ElementSet -> satrec initialization every other input format uses, so there is no separate TLE-direct propagation path.

The mapping is bit-preserving for SGP4. The angle, eccentricity, mean motion, and epoch-day fields are carried through unchanged until the epoch is converted through the same days2mdhms/jday math and 8-decimal fraction rounding Vallado uses for TLE input. B* and the second mean-motion derivative are decoded with powi in parse precisely so they equal the mantissa * 10^exp product the element-set initializer expects; they too pass through unchanged.

The catalog number is decoded to the numeric form ElementSet carries. It is used only for SGP4 diagnostics and does not affect propagation, but it must still survive the TLE bridge without silent loss.

Trait Implementations

impl Clone for TleElements

fn clone(&self) -> TleElements

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TleElements

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

Formats the value using the given formatter.

impl PartialEq for TleElements

fn eq(&self, other: &TleElements) -> 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.
