Abstract
An inertial control and measurement system is provided for applying inertial control to a vehicle and measuring angular rate of the vehicle. The system includes a control moment gyroscope having a spinning rotor, a gimbal, a gimbal support assembly attached to a spacecraft for allowing rotation of the gimbal about a gimbal axis, and a gimbal motor for rotating the gimbal about the gimbal axis to induce torque. A controller controls the gimbal motor to generate a control torque. The controller further determines an angular rate of the vehicle as a function of a determined torque and a gimbal angle acceleration.
