Abstract
The technical evolution of head mounted displays (HMDs) and micromechanical inertial sensor arrays (MMISAs) have, until recently, occurred independently. This thesis details the development and simulation results of an inertial helmet-mounted head tracker for a T- 38 jet aircraft flight environment. Primary focuses are the state error estimation filter and the bounding algorithms used to estimate the head position and orientation during various flight conditions. Also included is a discussion of the application of the Draper MMISA to a cueing system for an HMD in a military air vehicle environment. Particular attention is paid to necessary requirements to meet pointing accuracies for fire control system handoff applications for the next generation of air to air missiles, such as the AIM-9X Sidewinder missile. A Markov process coupling technique used in this research is shown to achieve pointing accuracies of 4 to 11 milliradians. A generalization of the navigation filter to any number of inertial navigators with known relative positioning and attitude coupled using Markov process propagation matrices is also included, along with examples of future applications, in addition to helmet-mounted cueing systems, for vehicle applications.
