Struct ECEFState 

pub struct ECEFState {
    pub epoch: DateTime<Utc>,
    pub position: Vector3,
    pub velocity: Vector3,
}

State vector in Earth-Centered Earth-Fixed (ECEF) reference frame.

ECEF is a rotating reference frame fixed to the Earth with:

• Origin at Earth’s center of mass
• X-axis pointing toward the intersection of the prime meridian and equator
• Z-axis pointing toward the North Pole
• Y-axis completing the right-handed system (90° East longitude)

Position is in kilometers and velocity is in km/s. Note: Velocity in ECEF includes the Earth’s rotation.

Fields

epoch: DateTime<Utc>

UTC epoch of this state

position: Vector3

Position vector in km

velocity: Vector3

Velocity vector in km/s

Implementations

impl ECEFState

pub fn new(epoch: DateTime<Utc>, position: Vector3, velocity: Vector3) -> Self

pub fn from_tuples( epoch: DateTime<Utc>, position: (f64, f64, f64), velocity: (f64, f64, f64), ) -> Self

Create from position and velocity tuples.

pub fn radius(&self) -> f64

Get the position magnitude (distance from Earth center) in km.

pub fn to_eci(&self) -> ECIState

Convert to ECI J2000 frame.

pub fn to_geodetic(&self) -> GeodeticState

Convert to geodetic coordinates.
