A novel design of gyrocompass consisting of a single axis Fiber Optic Gyroscope (FOG) and a Theodolite is proposed to meet the requirements of low-cost, fast and high-precision. This algorithm uses FOG data and theodolite encoder feedback to determine Azimuth. Micro computer based software is also discussed which was developed for implementation of this scheme; finally test results and plots are briefly presented which proves effectiveness of the designed methodology. By this design an accuracy of 0.08ois achieved in approximately 5 min time.
