INCORPORATING MODERN METHODS IN UNDERGRADUATE ASTRODYNAMICS EDUCATION
R.A. Madler - Embry-Riddle Aeronautical University
Abstract
While the basic physics behind modern astrodynamics has not changed, improvements in computational capacity and teaching methods have made modern astrodynamics accessible to the undergraduate curriculum. This paper discusses the evolution of the "Space Mechanics" course at the Prescott Campus of Embry-Riddle Aeronautical University (ERAU). Several years ago, this course followed the traditional lecture format of most undergraduate courses. The increased power of computers, software, and teaching media have made it possible to teach a more practical course in astrodynamics at the undergraduate level.
Traditionally, the undergraduate curriculum in most Aerospace Engineering departments in the country have leaned heavily towards Aeronautical Engineering with only a few courses devoted to space at best. This has allowed for only limited opportunities to teach real-life astrodynamics problems at the undergraduate level. With the increased use of computers in all aspects of engineering education, students are becoming more familiar with engineering computer applications. The "Space Mechanics" course at ERAU-Prescott is being restructured utilizing computing tools to enhance understanding of basic astrodynamic concepts and applications.
After several weeks of learning the basic concepts behind the two-body problem and refreshing their programming/computer skills, the students are introduced to Satellite ToolKit (STK). STK has been donated to ERAU-Prescott by Analytical Graphics Inc. for academic use. STK allows the students to better visualize orbits and examine how the orbit can be used for Earth studies. By the end of the semester, the students have a better understanding of astrodynamics as it relates to spacecraft mission design. This paper briefly discusses: a survey of astrodynamics courses in AE programs, the course outline, how computing tools are used to enhance student understanding, and an overview of future undergraduate astrodynamics courses.
