Definition

The perturbing force on a spacecraft in low orbit due to interaction with a rarefied atmosphere, related to atmospheric density, relative wind velocity, and the spacecraft's area-to-mass ratio.

Application Value

In orbit design and optimization, this concept is used to analyze spacecraft motion characteristics in the cislunar multi-body gravitational field, providing a theoretical basis for low-energy transfer trajectory design.
