Detailed Description

template<typename F, typename U = qtty::AstronomicalUnit>
struct siderust::BodycentricPos< F, U >

Result of a body-centric coordinate transformation.

Carries the relative position (target – body) and the embedded BodycentricParams needed for the inverse transform (to_geocentric). Mirrors Rust's Position<Bodycentric, F, U> which stores BodycentricParams at runtime.

Template Parameters

F	Reference frame tag (e.g. frames::EclipticMeanJ2000).
U	Length unit (default: qtty::AstronomicalUnit).

center_params()

template<typename F, typename U = qtty::AstronomicalUnit>

const BodycentricParams & siderust::BodycentricPos< F, U >::center_params ( ) const

inline

Access the embedded orbital parameters of the body.

Definition at line 95 of file bodycentric_transforms.hpp.

References params.

distance()

template<typename F, typename U = qtty::AstronomicalUnit>

U siderust::BodycentricPos< F, U >::distance ( ) const

inline

Distance from the body (norm of the embedded pos).

Definition at line 89 of file bodycentric_transforms.hpp.

References pos.

distance_to()

template<typename F, typename U = qtty::AstronomicalUnit>

U siderust::BodycentricPos< F, U >::distance_to ( const BodycentricPos< F, U > & other ) const

inline

Distance to another body-centric position.

Definition at line 92 of file bodycentric_transforms.hpp.

References pos.

to_geocentric()

template<typename F, typename U>

cartesian::Position< centers::Geocentric, F, U > siderust::BodycentricPos< F, U >::to_geocentric ( const Time< TT, JD > & jd ) const

inline

Transform back to geocentric coordinates.

Mirrors Rust's FromBodycentricExt::to_geocentric(jd). Uses the same params and jd as the original to_bodycentric() call.

Parameters

jd	Julian Date (same as the forward transform).

Returns

Geocentric position in the same frame and unit.
