- Tests energy comparison between analytical and numerical propagation
- Validates analytical propagation maintains zero energy drift
- Verifies numerical propagation has controlled, expected energy drift
- Tests energy comparison for circular, elliptical, high eccentricity, inclined, fast, and slow orbits
- Tests pre/post burn energy validation (ΔE = v·Δv + 0.5Δv²)
- Tests long-term energy drift comparison (10 orbits)
- Tests energy accuracy across all orbit types
- Validates analytical propagation is more energy-stable than numerical
