Public Functions Documentation¶

function ConstantMagneticField¶

Construct from a magnetic field vector.

explicit inertialsim::geodesy::ConstantMagneticField::ConstantMagneticField (
    const Vector3D & magnetic_field
)

Parameters:

magnetic_field 3x1 magnetic field vector in Tesla.

function Magnitude [¼]¶

Return magnitude at the given coordinates.

virtual Scalar1D inertialsim::geodesy::ConstantMagneticField::Magnitude (
    const Coordinates & coordinates
) const

Parameters:

coordinates Array of coordinates.

Returns:

Array of magnitudes.

Implements inertialsim::geodesy::Field::Magnitude

function Magnitude [2/4]¶

Return magnitude at the given coordinates.

Scalar1D inertialsim::geodesy::ConstantMagneticField::Magnitude (
    const Array3D & coordinates,
    CoordinateSystem default_frame=CoordinateSystem::GEODETIC
) const

Parameters:

coordinates Array of raw coordinates (e.g. geodetic).
default_frame Coordinate system corresponding to the coordinate input.

Returns:

Array of magnitudes.

function Magnitude [¾]¶

Return magnitude at the given coordinates.

Scalar1D inertialsim::geodesy::ConstantMagneticField::Magnitude (
    const geometry::Vector & coordinates,
    CoordinateSystem default_frame=CoordinateSystem::LOCAL
) const

Parameters:

coordinates Array of coordinates as geometry::Vector.
default_frame Coordinate system corresponding to the coordinate input.

Returns:

Array of magnitudes.

function Magnitude [4/4]¶

Return magnitude at the given coordinates.

Scalar1D inertialsim::geodesy::ConstantMagneticField::Magnitude (
    const Vector3D & coordinates,
    CoordinateSystem default_frame=CoordinateSystem::LOCAL
) const

Parameters:

coordinates Array of raw coordinates (e.g. local xyz).
default_frame Coordinate system corresponding to the coordinate input.

Returns:

Array of magnitudes.

function Vector [¼]¶

Return the vector field at the given coordinates.

inline Vector3D inertialsim::geodesy::ConstantMagneticField::Vector (
    const Coordinates & coordinates,
    const std::optional< CoordinateSystem > & basis=std::nullopt
) const

By default, the vector components will be expressed in the basis associated with the coordinates. For curvilinear systems (e.g. geodetic), the basis is the local basis at the given coordinates. If basis is supplied, it will be used instead.

Note:

For curvilinear coordinate systems like geodetic coordinates, the default basis is the local tangent plane basis at each coordinate location. For Cartesian systems like ECEF, the basis is constant.

Parameters:

coordinates Array of coordinates.
basis Optional basis in which to return the vector. If not specified, uses the basis associated with the coordinates.

Returns:

Array of vectors (3xN).

default_frame Coordinate system corresponding to the coordinate input.
basis Optional basis in which to return the vector.

Returns:

Array of vectors.

function Vector [4/4]¶

Return the vector field at the given coordinates.

Vector3D inertialsim::geodesy::ConstantMagneticField::Vector (
    const Vector3D & coordinates,
