Axes Transformations

In the section Axes Transformations libraries Aerospace you can perform transformations between different coordinate systems. These blocks allow you to calculate transformation matrices for the transition from a coupled coordinate system to a velocity coordinate system.


Besselian Epoch to Julian Epoch

Conversion of coordinates from epoch B1950.0 to epoch J2000.0.

Direction Cosine Matrix Body to Wind

Formation of the transformation matrix from the coupled coordinate system to the velocity coordinate system.

Direction Cosine Matrix Body to Wind to Alpha and Beta

Calculation of angles of attack and glide using the transformation matrix from the coupled coordinate system to the velocity coordinate system.

Direction Cosine Matrix ECEF to NED

Formation of the conversion matrix from ECEF to NED.

Direction Cosine Matrix ECEF to NED to Latitude and Longitude

Computation of latitude and longitude using the conversion matrix from ECEF to NED.

Direction Cosine Matrix to Rodrigues

Creating a finite rotation vector from a rotation matrix.

Direction Cosine Matrix to Wind Angles

Calculation of angles between the axes of the velocity and normal coordinate systems using the transformation matrix.

Geocentric to Geodetic Latitude

Transition from geocentric latitude to geodetic latitude.

Geodetic to Geocentric Latitude

The transition from geodetic latitude to geocentric latitude.
