Abstract: The research contribution is increasing in the field of autonomous spacecraft. The major role contributes to the navigation methods for spacecraft. The intended control design is required precision mirror rate sensor (PMRS) to maintain positioning and stability of the satellite. One major drawback of the PMRS resides in the lock in effect, by which the sensor is not capable of sensing the rotation at low inertial angular rates. In the proposed work due to the uniqueness, it is able to sense the rotation even at the low inertial angular rates. The frequency control loop has been designed, it generates the resonance frequency using dither motor. The frequency control loop of the PMRS, is developed using a 32 bit MICROBLAZE soft core processor along with PID algorithm and same is executed using Xilinx Spartan 6 FPGA. 
Keywords: PMRS(precision mirror rate sensor), lock-in Effect, Dither, PID Controller.
