The triad of mission geometry, orbit/constellation design, and management is inseparable. Geometry provides the geometric constraints and opportunities; design synthesizes those into robust orbital architectures; management ensures that the ideal geometry is sustained against the harsh realities of astrodynamics. A masterful PDF on this topic is not just a collection of formulas but a systems engineering guide—linking ΔV budgets to revisit times, and orbital perturbations to operational procedures.
For the practitioner, mastering this material means being able to answer: “Given a desired coverage pattern, what constellation do I build, and how do I keep it flying for ten years?”
