Abstract	Title: Affordable State Estimation for Guided Mortar Systems Presenter: Dr. Jonathan Rogers, Assistant Professor, Texas A&M University Abstract: Affordability requirements continue to place a heavy burden on development of guided projectiles. State estimation packages and control actuation systems are the primary cost drivers for these systems, in large part due to accuracy requirements, g-hardening constraints, and the small space available for actuators and electronics. This talk outlines new developments in smart weapons guidance and control systems, with an emphasis on non-traditional sensor packages that have significantly lowered the cost of state estimators without undue penalty in performance. In particular, an estimator package receiving feedback from large field-of-view IR sensors (thermopiles), magnetometers, and trajectory predictions has shown great promise in providing accurate orientation estimates in flight at very low cost. Additional work has explored alternative position and velocity navigation techniques using MEMS barometers and thermopiles coupled with heuristic predictions. The talk will conclude with an outlook for future affordable state estimation work including ongoing vision-based navigation research being conducted at Texas A&M’s Helicopter and Unmanned Systems Lab.
