By the end
What you'll build
- Explain and compute two-body orbits — speed, period, shape and energy — from first principles with the vis-viva equation
- Solve Kepler's equation numerically with numpy and locate a satellite anywhere on its orbit from time alone
- Read real Two-Line Element sets fluently and recover orbital elements, including semi-major axis from mean motion
- Design and price orbital maneuvers — Hohmann transfers, plane changes and GTO insertions — in delta-v
- Propagate real satellites with SGP4 and skyfield to generate ground tracks and predict passes over your own city
