Aiming for the application to the future spacecraft attitude control system, we are studying the high performance Fiber Optic Gyro Inertial Reference Unit (FOG-IRU). To fulfill the requirements of low noise, stable bias and stable scale factor, we adopt the high power Fiber Light Source, a long fiber coil (several kilo-meters) and the digital serrodyne closed loop configuration. This paper outlines the result of our FOG-IRU development during FY16 such as evaluation of the FOG Pre-EM model, evaluation of the temperature characteristics of the Pre-EM model, evaluation for the optical error factor, designs and re-fabrication for the performance improvement, and evaluation of the Pre-EM re-fabrication model.
