Struct TwoLineElement

pub struct TwoLineElement { /* private fields */ }

A parsed, valid Two Line Element data set which can be used for orbital propagation.

Internally this uses SGP4’s own structure representation. Various fields which are useful for analysis or simulation are exposed via methods like raan()/set_raan() which allow access to the values and direct modification of the underlying orbital element set in a type-safe manner. The uom crate provides dimensional analysis to help avoid unit-of-measure errors which can otherwise be quite difficult to detect.

Implementations

impl TwoLineElement

pub fn new(line1: &str, line2: &str) -> Result<TwoLineElement, Error>

Create a validated TwoLineElement from a string.

pub fn from_lines(combined_lines: &str) -> Result<TwoLineElement, Error>

Create a TwoLineElement from a string containing both lines, and optionally a header line.

pub fn epoch(&self) -> Result<DateTime<Utc>, Error>

Get the epoch of a TwoLineElement.

pub fn mean_motion(&self) -> AngularVelocity

pub fn propagate_to(&self, t: DateTime<Utc>) -> Result<StateVector, Error>

Propagate a TwoLineElement to the given time to obtain a state vector for the object.

Trait Implementations

impl Clone for TwoLineElement

fn clone(&self) -> TwoLineElement

Returns a copy of the value.

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