Abstract
Thales Visionix has developed a new helmet tracker based on a hybrid inertial optical approach. It uses the inside-out concept of the InterSense VisTracker technology, which has been acquired by Thales Visionix, upgraded with a tiny high-performance NavChip Inertial Measurement Unit (IMU). A unique feature of the tracker is that there is no aircraft mounted equipment. A group of small circular barcode-like fiducial stickers are placed on the interior surface of the cockpit. The tracker allows operation in both hybrid inertial/optical and inertial-only modes, which it seamlessly switches between as the pilot’s helmet goes in and out of the optical tracking zone. This paper describes the tracker, its features and performance.
