The study of this paper involves establishing an optimal retargeting manoeuvre for an agile Earth Observation satellite and investigating the criteria to perform the manoeuvre. Reaction wheels in a 4-wheel pyramid structure are considered as torque actuators. An optimal manoeuvre is calculated for the shortest distance to a target orientation, and an attitude tracking method is employed to perform the manoeuvre. The results are validated through a numerical simulation.

Abstract
The study of this paper involves establishing an optimal retargeting manoeuvre for an agile Earth Observation satellite and investigating the criteria to perform the manoeuvre. Reaction wheels in a 4-wheel pyramid structure are considered as torque actuators. An optimal manoeuvre is calculated for the shortest distance to a target orientation, and an attitude tracking method is employed to perform the manoeuvre. The results are validated through a numerical simulation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
