Mission Geometry; Orbit and Constellation Design and Management by James R. Wertz is a foundational text, providing rigorous algorithms for spacecraft orbit, attitude systems, and constellation management. The work is recognized as an industry standard for designing and maintaining satellite constellations. For more details, visit Astrobooks .
160–2,000 km altitude. High resolution for imaging but requires many satellites for global coverage. For more details, visit Astrobooks
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. If your mission geometry is flawed, the spacecraft
