Definition

A physical quantity describing a spacecraft's sensitivity to atmospheric drag, defined as the ratio of mass to the product of drag coefficient and cross-sectional area.

Application Value

Ballistic Coefficient plays an important role in orbital dynamics and attitude control, serving as a critical tool for analyzing spacecraft motion characteristics. Research on this concept enables optimization of orbit transfer schemes and improvement of control system performance.
