Implementations

impl BPlane

pub fn from_dual(orbit: OrbitDual) -> Result<Self, AstroError>

Returns a newly define B-Plane if the orbit is hyperbolic and already in Dual form

pub fn new(orbit: Orbit) -> Result<Self, AstroError>

Returns a newly defined B-Plane if the orbit is hyperbolic.

pub fn inertial_to_bplane(&self) -> Matrix3<f64>

Returns the DCM to convert to the B Plane from the inertial frame

pub fn jacobian(&self) -> Matrix3<f64>

Returns the Jacobian of the B plane (BR, BT, LTOF) with respect to the velocity

pub fn jacobian2( &self, invariant: StateParameter, ) -> Result<Matrix2<f64>, AstroError>

Returns the Jacobian of the B plane (BR, BT) with respect to two of the velocity components

impl BPlane

pub fn b_dot_t_km(&self) -> f64

Returns the B dot T, in km

pub fn b_dot_r_km(&self) -> f64

Returns the B dot R, in km

pub fn ltof(&self) -> Duration

Returns the linearized time of flight, in seconds

NOTE: Although the LTOF should allow to build a 3x3 Jacobian for a differential corrector it’s historically super finicky and one will typically have better results by cascading DCs which target different parameters instead of trying to use the LTOF.

pub fn angle_deg(&self) -> f64

Returns the B plane angle in degrees between -180 and 180

pub fn magnitude_km(&self) -> f64

Returns the B plane vector magnitude, in kilometers
