Orbital Mechanics Basics

Orbital Mechanics Basics is an entry-level educational tool designed for those interested in rocketry and satellite engineering. The tool provides a way to manipulate three key orbital elements—semi-major axis (a), eccentricity (e), and inclination (i)—using a set of canonical presets corresponding to typical orbital environments such as Low Earth Orbit (LEO), Geostationary Earth Orbit (GEO), the Moon, and Mars. Users can adjust these parameters for different central bodies, including Earth and the Sun, and can also input custom mass values for the central body. The platform allows users to explore fundamental orbital mechanics concepts by visualizing how changes in orbital elements affect various orbital characteristics. Output parameters include orbital period, periapsis and apoapsis altitudes, periapsis and apoapsis velocities, and specific orbital energy. The tool also provides key theoretical formulas, such as Kepler's third law and the vis-viva equation, to support learning and reference. Orbital Mechanics Basics is accessible as a web-based application. It is positioned as a resource suitable for beginners or those seeking a foundational understanding of satellite orbits and related physical principles.
