It is known that angel sensor signal shares the same frequency with induction torquer current.Based on this fact

the analog rebalance loop used in induction torquer is designed in response to the need of torque feedback testing of single freedom rate integrating gyroscope drift.The working principle of the rebalance loop is analyzed and the main parts of the circuit are described.The experimental results indicate that both dynamic and static performances can meet the requirement for practical application

while the rebalance loop which is simple and reliable has the advantages of high sensitivity.
