My Background
• 20 years in the USAF
– technician, satellite systems engineer, and professor
• 5½ years at the Air Force Institute of Technology
– Taught space systems engineering, nonlinear dynamics and
control
– 27 M.S. students and 3 Ph.D. students in space-related
research
• 5 years at Virginia Tech
– Teaching space design and spacecraft dynamics and control
– 11 M.S. students and 3 Ph.D. graduated, now working at
NASA, USAF, Lockheed-Martin, Analytical Graphics, a.i.Solutions, Orbital Sciences, AeroAstro, RealTime Inc.,
Draper Lab
– Currently advising 3 Ph.D. students, 5 M.S. students, as well
as several undergrads
– Research supported by NASA, NSF, and USAF
Space-Related Courses
• Astromechanics – required course on orbital motion
– Satellite Tracking Lab in Randolph 311A will give students
hands-on experience in tracking amateur satellites, and may
someday be used as ground station for HokieSat
• Attitude Dynamics and Control – tech elective on
satellite pointing motion (required for Space Design)
– Space Systems Simulation Lab will give students hands-on
experience in attitude dynamics and control
• Space Design – Senior Capstone Design Course
– Students work in teams to design a space vehicle
– HokieSat started as a senior design project
– Sounding Rocket payload is current long-term project

Spacecraft Simulators
• Distributed Spacecraft
Attitude Control System
Simulator (DSACSS)
• Two spherical air
bearings with assorted
subsystems
• Hardware integration,
software development
• Jana Schwartz (g),
Marcus Pressl (g),
Eugene Skelton (g),
Mike Shoemaker (u),
Cengiz Akinli (u)
Astrodynamics Toolbox
• Develop a suite of subroutines in Matlab
and/or C++
• Develop graphical user interfaces for typical
AOE 4134 calculations
% function [oe,epoch,yr,M,E,satname] = TLE2oe(fname);
%
fname is a filename string for a file containing
%
a two-line element set (TLE)
%
oe is a 1/6 matrix containing the orbital elements
%
[a e i Om om nu]
%
yr is the two-digit year
%
M is the mean anomaly at epoch
%
E is the eccentric anomaly at epoch
%
satname is the satellite name
%
% Calls Newton iteration function file EofMe.m
function [oe,epoch,yr,M,E,satname] = TLE2oe(fname)
% Open the file up and scan in the elements
