Satellite missions are becoming increasingly important for a wide range of applications, including Earth observation, communication, navigation, and scientific research. The success of a satellite mission depends on a variety of factors, including the selection of the right orbit, the design of the satellite constellation, and the effective management of the mission. In this article, we will explore the key concepts and techniques involved in mission geometry orbit and constellation design and management. – The NASA Technical Reports Server (NTRS) hosts

Many papers on constellation design come from the International Conference on Astrodynamics. They often publish proceedings that detail the math behind missions like GPS or Galileo. They provide unobstructed views of the Sun or
Choosing the right orbit depends entirely on the mission objective, such as telecommunications, imaging, or navigation.
Counteracting the effects of atmospheric drag, Earth’s non-spherical shape ( J2cap J sub 2 effect), and solar radiation pressure.
Below is a comprehensive guide and overview of the fundamental principles of satellite mission geometry, orbit selection, constellation design, and active fleet management.
Design your constellation so that if one satellite fails, the "geometry" of the remaining fleet still meets minimum mission requirements. The success of a satellite mission depends on
Ensuring compliance with international guidelines (e.g., the 25-year rule or newer stricter mandates) by lowering perigee for atmospheric reentry.
The time duration a satellite has a line of sight to a specific ground target.
