Non-conservative torque and attitude modelling for enhanced space situational awareness

Aug 01, 2014

Virdee, {Hira S.} and Santosh Bhattarai and Stuart Grey and Marek Ziebart

The tumbling of space debris is an important problem, as the evolving attitude of debris directly influences the forces on it and therefore perturbs its orbit. This paper investigates the torque induced by solar radiation pressure (SRP) on Envisat and the resulting changes in attitude. These changes are compared to observations.
