Dr. Christopher J. Hegarty
is a director with The MITRE Corporation, where he has worked mainly on aviation applications of GNSS since 1992. He received his D.Sc. in electrical engineering from The George Washington University. He is currently the Chair of the Program Management Committee of RTCA, Inc., and co-chairs RTCA Special Committee 159 (GNSS). He served as editor (1997 -2006) of NAVIGATION: The Journal of the Institute of Navigation and is presently the U.S. Institute of Navigation (ION)’s Executive Vice President.
For his contributions to GNSS, he was a recipient of the U.S. Department of State Superior Honor Award in 2005, the ION Kepler Award in 2005, and the Worcester Polytechnic Institute Hobart Newell Award in 2006. He is a Fellow of the ION, and co-editor/co-author of the textbook Understanding GPS: Principles and Applications, 2nd Ed.
Lecture: Positioning & Navigation Algorithms and Processing
This lecture addresses algorithms for estimating position, velocity, and time (PVT) using GNSS measurements. Point solution algorithms, which are based upon measurements from a single epoch, are first described. A brief introduction to Kalman filtering, which extracts useful information from past, in addition to current measurements, is also provided.
