Integration: It speeds up the process of merging previously separate disciplines—orbit and attitude systems—due to the rise of extensive on-board computing. Orbit : MEO, 23,222 km, 3 Walker planes

7. Case Study: Galileo Constellation Management

Orbit: MEO, 23,222 km, 3 Walker planes (56° inclination), 9 operational + 2 spares per plane.
Geometry challenge: Maintain RAAN spacing despite luni-solar perturbations.
Management: Regular phasing maneuvers every few months; spares are kept in slightly offset orbits for rapid repositioning.
PDF lesson: Show how a single outage (e.g., satellite clock failure) triggers a re-plan of the constellation geometry using spare repositioning.

Why Geometry Dictates Mission Success

If your mission geometry is flawed, the spacecraft may drift into perpetual shadow (loss of power) or lose thermal control. For remote sensing, poor geometry leads to oblique imagery with distorted resolution. The best PDFs on this topic use vector diagrams and spherical trigonometry to model these constraints. Why Geometry Dictates Mission Success If your mission

3. Constellation Management (The Swarm)

This is the modern challenge.

Orbit Mechanics: You aren't just fighting gravity; you are managing atmospheric drag, solar radiation pressure, and lunar perturbations.
Geometry: It’s a 4D chess game. You have to design an orbit so that a satellite passes over a specific ground target at a specific time, while simultaneously ensuring it can see a relay satellite to downlink data.
Constellation Management: If you have 1,000 satellites, how do you ensure they don't crash into each other or space debris? This is "Astrodynamics on an industrial scale."

2. Orbit Design (The Path)

This is choosing the right altitude and shape.
