Not its mass directly, but you can use it to calculate the moment of inertia. Move the CMGs a fixed angle and looking at the responding change in rate of the ISS. Mass can be determined from maneuvers when you fire the thrusters. Assuming you know the force from the thrusters very well (this has its own errors) you can look at the acceleration from the orbit determination before and after the thruster burns and back out the mass. |
