Axes Transformations

Transform axes of coordinate systems to different types, such as Euler angles to quaternions and vice versa

Axes transformation functions support transformations such as those between:

• Direction cosine matrices and quaternions

• Rotation angles and quaternions

• Earth-centered inertial (ECI) coordinates and azimuth or geodetic latitude, longitude, altitude (LLA) coordinates

• Flat Earth positions from geodetic latitude, longitude, and altitude
