Axes Transformations

Coordinate axes transformations, such as Euler angles to quaternions and Euler-Rodrigues angles to quaternions

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
