Struct LaunchAngles 

pub struct LaunchAngles {
    pub azimuth_rad: f64,
    pub elevation_rad: f64,
    pub roll_rad: f64,
}

The attitude of the body axis relative to the launch frame, as launch-rail style angles.

q = R_z(−A) ⊗ R_x(E − π/2) ⊗ R_z(φ), so the body axis z_B points along (sin A cos E, cos A cos E, sin E) in the launch frame. At E = ±90° azimuth and roll turn about the same axis; LaunchAngles::from_quaternion then reports A = 0 and puts the whole turn into φ.

Fields

azimuth_rad: f64

Azimuth A of the body axis, rad, clockwise from true north (π/2 points east).

elevation_rad: f64

Elevation E of the body axis above the horizon, rad (π/2 is vertical).

roll_rad: f64

Roll φ about the body axis, rad, right-handed about z_B.

Implementations

impl LaunchAngles

pub fn to_quaternion(self) -> DQuat

The attitude quaternion q = R_z(−A) ⊗ R_x(E − π/2) ⊗ R_z(φ).

pub fn from_quaternion(q: DQuat) -> Self

The launch angles of a unit attitude quaternion, with A ∈ [0, 2π), E ∈ [−π/2, π/2] and φ ∈ (−π, π].

Trait Implementations

impl Clone for LaunchAngles

fn clone(&self) -> LaunchAngles

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LaunchAngles

impl Debug for LaunchAngles

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LaunchAngles

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LaunchAngles

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
