Design and Application of a Hand-held Orbital Trainer-Based Satellite Orbit Education Program

This study developed and implemented an orbital mechanics training program using a and-held orbital trainer to enhance experiential learning. Following the ADDIE instructional design model, a four-session curriculum was designed in which students manipulated the six classical orbital elements to observe changes in orbital geometry and ground tracks. The program was applied to 94 second-year cadets enrolled in the 45-hour Introduction to Astronautical Engineering course at the Korea Air Force Academy. Post-implementation evaluation was conducted through a satisfaction survey (10 items, 5-point Likert scale) and qualitative feedback. Results showed high overall satisfaction with the highest ratings for “learning effectiveness and applicability.” Pearson correlation analysis confirmed significant positive associations among usability, theory–practice linkage, and perceived learning outcomes. Open-ended responses indicated increased conceptual clarity, motivation, and engagement, while suggestions focused on expanded practice time and additional instructional materials. These findings demonstrate that the hand-held orbital trainer effectively supports visualization-based understanding of orbital mechanics, bridging the gap between abstract theory and applied learning. The instructional approach can be adapted for broader use in astronautical engineering education and related training programs.
