Thomas H. Kerr III is a Ph.D. electrical engineer experienced in the theory and applications of Kalman filters and its Digital Signal Processing (and in the underlying mathematics, physics, and its supporting modeling & simulation). His R&D System Engineering experience has been in INS, JTIDS RelNav, GPS, and INS/GPS navigation for both U.S. Navy and Air Force, and in target tracking for strategic Early Warning Radars in national defense roles (SDI, NMD\UEWR), with some countermeasure considerations. He was involved with D-1 Trident and C-4 back-fit Poseidon SSBN SINS/ESGM navigation development from 1973-1979 (where he developed an original automated failure detection algorithm for the ESGM as a Kalman filter real-time accoutrement involving Two Confidence Regions and also posed and solved the problem of SSBN external navigation aid ("navaid") fix utilization while evading enemy surveillance as a “cat-and-mouse” game of “sensor schedule optimization” within a natural Kalman Nav filter context), with GPS DT&E(OR) on-board SSN-701 La Jolla (1980’s), and with airborne GPS/INS (1990’s) and in 2003 for the Navy’s ACOSS Littoral Surveillance. He has also been involved with analysis in support of IV&V of Navy LAMPS Lofar/Difar & other sonar and sonobuoy target tracking (1980’s). He uses Monte-Carlo simulation of the above to set parameters and substantiate conclusions. He has published extensively (~130+) in company technical reports and in peer-reviewed technical literature and has received 999+ citations from other independent authors and researchers worldwide. He has received two awards for technical writing: (1) in 1967, from the Federal Power Commission in a competition between engineering schools in the metropolitan Washington D.C. area; (2) in 1988, the M. Barry Carlton Award for Best Paper in IEEE TAES in 1987. AIAA GNC Associate Fellow/IEEE Life Senior Member, Institute of Navigation (ION), NDIA Life member.
