The toolbox supports the representation and updating of attitude through quaternions as well as direction cosines. The toolbox provides the following functions:
- QUAUPDAT – Update quaternion body-to-nav attitude vector
- QUAMULT – perform quaternion multiplication
- QUA2DCM – convert from quaternion to direction cosine matrix
- EULR2QUA – convert from Euler angles to quaternion
- DCM2QUA – convert from direction cosine matrix to quaternion
