FURTHER STUDY ON ATTITUDE ACQUISITION OF A SATELLITE WITH A PARTIALLY-FILLED LIQUID TANK

The wheel spin-up for spacecraft reorientation using a momentum transfer technique is limited by the amount of available satellite power, and by the allowed time period for the maneuver. Therefore, determination of the desired spin-up strategy and acquisition time constant are primary issues in a momentum transfer maneuver. In this study, an analytical method to determine an appropriate wheel spin-up scheme and the acquisition time constant is developed and compared to numerical simulations and show excellent agreements.
