A new method to identify the mass parameters of spacecraft

A new method to identify the mass parameters of spacecraft

A two-step identification method is proposed, both the moment of inertia and the mass properties are identified. A new index parameter which is different from the commonly used condition number is first defined for designing the optimal excitation. A method is introduced based on the least squares a...
