摘要
Mass property of spacecraft needs to be estimated in certain circumstances.Based on the measurement of single point acceleration,angular acceleration and angular velocity,a discrete Kalman Filter(KF) based estimation method is developed to extract the inertia matrix and mass center.The simulation results show that the method can be used for continues online estimation without propellant consumption.Stability condition for the filter is given at last.
Mass property of spacecraft needs to be estimated in certain circumstances. Based on the measurement of single point acceleration, angular acceleration and angular velocity, a discrete Kalman Fiher （KF） based estimation method is developed to extract the inertia matrix and mass center. The simulation results show that the method can be used for continues online estimation without propellant consumption. Stability condition for the filter is given at last.
