Which acronym stands for the system that provides the roll, cross roll, and the pointing azimuth relative to true north?

Explanation:
Roll and the heading relative to true north are outputs of an attitude/heading reference system. This type of system uses angular-rate sensors and gravity references to determine the vehicle’s orientation and where it’s pointing in relation to true north. In this material, the system that provides those exact outputs—roll, cross-roll, and the pointing azimuth relative to true north—is HANFS. GPS only gives position and velocity, not orientation; IFF relates to identification; and while an inertial navigation system can determine attitude, the source specified for these outputs in this context is HANFS.
