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 ($LS 100 ppm) over a high dynamic range ($POM 1400$DGR@/s), low random walk ($LS 0.02$DGR@/$ROOT@hr), and outstanding bias stability over temperature and day-to-day ($LS 1$DGR@/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. !9
