# Test Configuration: Hohmann Transfer Between Coplanar Circular Orbits |
|
# Three spacecraft in circular, coplanar LEO orbits around Earth |
|
# Tests Hohmann transfer phasing calculations in both directions |
|
# |
|
# Configuration: |
|
# - Target_Satellite: middle orbit (reference) |
|
# - Chaser_Lower: lower orbit, will transfer UP to target |
|
# - Chaser_Higher: higher orbit, will transfer DOWN to target |
