AESS will charge a nominal fee for this tutorial to cover speaker expenses. We will provide additional details separately on this significant event for the Huntsville Section IEEE.
GPS AND INERTIAL DATA PROCESSING
Dr. James L. Farrell, VIGIL, Inc.
The first half-day will benefit those who have never processed GPS data.
Sinple graphics illustrate orbital parameters and, with real satellite measurements, solutions are computed for navigation and timing while demonstrating satellite geometry effects. Graphical demonstration and computation of performance achievable in a simulated cruise flight closes the introductory session.
In t he second half-day, Dr. Farrell demonstrates applying GPS updating to a low-cost inertial measuring unit (IMU). He shows how the end user can discard unnecessary complexity of traditional mechanizations, an outgrowth of yesteryear's limited computing capabilities. Using the resulting simplified approach, he demonstrates applicability to the overwhelming majority of practical operations and validates results by state-of-the-art performance using van and flight test results with a low-cost IMU.
Presenter Bio:
Dr. Farrell holds a M.S. degree from UCLA (1961) and a Ph.D. degree from the University of Maryland (1967) and is a registered professional engineer in Maryland. He is a former ION Air Representative, an ION Fellow, an IEEE Senior Member, a former local board member of AIAA, a registered professional engineer in Maryland, and member of various scholastic honorary fraternities. Technical experience includes teaching appointments at Marquette and UCLA, two years each at Minneapolis Honeywell and Bendix-Pacific, plus 31 years at Westinghouse in design, simulation, and validation of navigation and tracking programs.
He is author of Integrated Aircraft Navigation (Academic Press, 1976; now in paperback after five hard-cover printings), is a former columnist for Washington Technology, and has written over 80 journal and conference manuscripts. He served as co-chairman of an RTCA Working Group for GPS Integrity. With VIGIL Inc. he has continued his teaching (on University campus as well as in both industry and conference seminars), while consulting for private industry, DOD, and University research. His main area of activity is now in GPS/inertial integration, writing programs validated with test data collected by Ohio University.
