When one satellite isn't enough, we build constellations. Designing these requires complex mathematical "patterns" to ensure global coverage. Defined by is inclination, is the total number of satellites, is the number of planes, and

Implementing software pipelines that ingest Space Situational Awareness (SSA) data to automatically execute evasive maneuvers. Decommissioning and Space Sustainability
Calculating the "footprint" or "swath" of a satellite sensor. When one satellite isn't enough, we build constellations
The azimuth and elevation required for a ground station to "see" a satellite.
The definitive guide to covers how modern space systems optimize satellite placement, coverage loops, and lifecycle operations. Fundamental Mission Geometry and Orbit Design
Before diving into the technical details, it's worth understanding the unique stature of the Wertz book. It is part of the prestigious and is the most complete treatment available for many elements of space mission design and astronautics. However, digital copies may be accessible through academic
: The book is designed for working engineers, featuring "numerical recipes," formulas, and insights derived from 40 years of spaceflight experience.
: It is used both as an introductory text for those entering the field and as a reference work for senior engineers. Complementary Resources

A type of LEO where the orbital plane precesses at the same rate as the Earth's average solar orbit. This maintains a constant local solar time at the ground track nodes, ensuring uniform illumination conditions for optical imaging.
Mission geometry defines the spatial and temporal relationships between spacecraft, celestial bodies, and ground targets. Accurate geometric modeling ensures that payloads achieve their scientific or operational objectives.
Selecting the right orbit is a foundational decision that dictates spacecraft launch requirements, payload capabilities, and lifespan.
Design your constellation so that if one satellite fails, the "geometry" of the remaining fleet still meets minimum mission requirements.
