WebDec 14, 2012 · A Demonstration of Linear Satellite Orbit Propagation Using Clohessy-Wiltshire Equations of Motion. WebJul 26, 2024 · Generally, the linearized, simplified model of the relative motion is described using time-invariant, Hill-Clohessy-Wiltshire (HCW) equations developed in 1960s. This model was based on the assumptions that, the chief and deputy spacecraft are in close proximity and the chief spacecraft is in a near circular orbit.
