Struct LaunchFrame 

pub struct LaunchFrame { /* private fields */ }

An East-North-Up frame tied to a point on an ellipsoid: the launch frame L.

Implementations

impl LaunchFrame

pub fn new(ellipsoid: Ellipsoid, origin: Geodetic) -> Result<Self, CoreError>

The ENU frame with its origin at origin on ellipsoid.

Errors

CoreError::Domain if origin fails Geodetic::new’s checks (for example degrees written into the radian fields).

pub fn wgs84(origin: Geodetic) -> Result<Self, CoreError>

The ENU frame at origin on the WGS 84 ellipsoid.

Errors

As LaunchFrame::new.

pub fn ellipsoid(&self) -> Ellipsoid

The ellipsoid the frame is tied to.

pub fn origin(&self) -> Geodetic

The origin’s geodetic position.

pub fn origin_ecef_m(&self) -> DVec3

The origin’s ECEF position, m.

pub fn ecef_from_enu_rotation(&self) -> DMat3

The rotation mapping launch-frame components to ECEF components; its columns are ê, n̂ and û at the origin.

pub fn ecef_from_enu(&self, position_enu_m: DVec3) -> DVec3

ECEF position of a point given in the launch frame: r_ECEF = r_0 + R r_L.

pub fn enu_from_ecef(&self, position_ecef_m: DVec3) -> DVec3

Launch-frame position of a point given in ECEF: r_L = Rᵀ (r_ECEF − r_0).

pub fn geodetic_from_enu( &self, position_enu_m: DVec3, ) -> Result<Geodetic, CoreError>

Geodetic position of a point given in the launch frame.

Errors

As Ellipsoid::geodetic_from_ecef: only for non-finite input or points deep inside the Earth.

pub fn enu_from_geodetic(&self, point: Geodetic) -> DVec3

Launch-frame position of a geodetic point.

pub fn earth_rotation_enu_rad_s(&self, omega_rad_s: f64) -> DVec3

The Earth’s rotation vector Ω = ω (0, cos φ₀, sin φ₀) resolved in the launch frame, rad/s, for a rotation rate omega_rad_s (WGS 84: 7.292115e-5 rad/s).

Trait Implementations

impl Clone for LaunchFrame

fn clone(&self) -> LaunchFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LaunchFrame

impl Debug for LaunchFrame

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LaunchFrame

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LaunchFrame

fn eq(&self, other: &LaunchFrame) -> 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 LaunchFrame

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
