Paper Abstract

Requirements for a gyroscope intended for use in land navigation in a coupled dead- reckoning/GPS navigation system are governed more by economics than by performance. As a result, explicit performance requirements are poorly defined by the users. The development of a low-cost fiber optic gyro for this application is described. Using a short coil length, and simple packaging concepts, it represents an evolutionary approach to meeting evolving specifications. Based on elliptical-core polarization maintaining D fiber, fused fiber couplers and an on-fiber polarizer, the components are assembled by fusion splicing. The optical circuit loss is low, permitting use of a low power optical source. Signal processing is considerably simpler than for stand-alone inertial navigation systems, and the challenge is to minimize cost. The packaging concept is intended to facilitate assembly.
