| Abstract: | North finder
capability gyroscopes supply the reference north azimuth information to the
relevant base system. This paper covers the design details of both optical and
electronic components of an open-loop Interferometric Fiber Optic Gyroscope
(IFOG) with integrated-optic phase modulator LiNbO3 and the
measurement results of earth rotation rate carried out by means of the designed
north finder IFOG with LiNbO3 modulator in laboratory plane
together. Scale factor model function is
derived for the open-loop IFOG with LiNbO3. Additionally, bias
stability and the temperature dependence of the bias stability for the north
finder IFOG have been studied in the temperature range 23°-42°C. |
