Thales Visionix, Inc. presented a new helmet tracker based on a hybrid inertial optical approach in 2013.  The Hybrid Optical based Inertial Tracker (HObIT) uses the inside-out concept and InterSense NavChip precision Inertial Measurement Unit (IMU).  A unique feature of the tracker is that there is no aircraft mounted equipment.  A few circular bar code like fiducial stickers are placed on the interior surface of the cockpit.  The tracker allows operation both in hybrid inertial/optical sensor fusion mode, and for periods of time using inertial sensors alone.  The HObIT has been installed and successfully flown on a number of different platforms.  This paper will describe the different installations and the performance achieved by the HObIT.
