A Tactical Fiber Optic Gyro with All-Digital Signal Processing

Michael Perlmutter

Abstract:	Northrop’s Electronics System Division has built and tested a tactical fiber optic gyro (FOG) with all-digital signal processing. The Northrop FOG uses 160 meters of polarization maintaining optical fiber wound on a spool 29 mm in diameter. Without any data compensation, this FOG has demonstrated excellent scale factor stability and non-linearity (< 100 ppm) over a high dynamic range (& 14OO”/s), low random walk ( < 0.02’/&), and outstanding bias stability over temperature and day-to-day (< lO/hr). An Inertial Measurement Unit (IMU) utilizing a FOG/MSA (Micro Silicon Accelerometer) cluster has been developed and integrated with a GPS receiver. Testing was done to demonstrate performance of the sensor and IMU over the military environment.
