Struct Earth 

pub struct Earth { /* private fields */ }

The Earth model for one launch site.

Implementations

impl Earth

pub fn new( field: NormalGravity, site: Geodetic, gravity: GravityModel, rotation: EarthRotation, ) -> Result<Self, CoreError>

The Earth model for a launch site at site (on the field’s ellipsoid).

Errors

CoreError::Domain if the site is not a valid geodetic position, or a constant gravity magnitude is negative or not finite.

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

The WGS 84 Earth at site, with the default models: ellipsoidal gravity and Coriolis.

Errors

As Earth::new.

pub fn field(&self) -> &NormalGravity

The normal gravity field.

pub fn frame(&self) -> &LaunchFrame

The launch frame.

pub fn gravity_model(&self) -> GravityModel

The gravity model.

pub fn rotation(&self) -> EarthRotation

The rotation terms included.

pub fn angular_velocity_enu_rad_s(&self) -> DVec3

The Earth’s angular velocity Ω = ω (0, cos φ₀, sin φ₀) resolved in the launch frame, rad/s, whichever terms are enabled.

pub fn gravity_enu_mps2( &self, position_enu_m: DVec3, ) -> Result<DVec3, CoreError>

Gravity at a launch-frame position, resolved in the launch frame, m/s².

Errors

CoreError::Domain for a non-finite position, or (for the ellipsoidal model) a position hundreds of kilometers inside the Earth.

pub fn rotation_acceleration_enu_mps2(&self, velocity_enu_m_s: DVec3) -> DVec3

The Earth-rotation acceleration on a body moving at velocity_enu_m_s relative to the launch frame: −2 Ω × v with Coriolis enabled, zero otherwise, m/s².

Trait Implementations

impl Clone for Earth

fn clone(&self) -> Earth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Earth

impl Debug for Earth

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Earth

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Earth

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
