Abstract

Navigation grade fiber optic rotation sensors (FORS) are being developed as an alternative to spinning mass gyro's for unmanned planetary exploration spacecraft. FORS is attractive because of its many advantages such as long life, low weight, low power and low cost as compared to its mechanical counterparts. FORS incorporates an advanced integrated optics circuits fabricated for JPL by AT&T Bell Laboratories. The advanced 8-component integrated optics circuit performs all the key signal processing functions and in addition incorporates a unique optical beat detection circuit (OBDC)2 thereby providing an output in the form of pulses proportional to incremental angular position similar to a ring laser gyro (RLG) but without the inherent lock-in problem RLG's possess.
