Abstract :
Navigation and positioning system is one of critical subsystems of Synthetic Aperture Sonar (SAS). Based on the Dead Reckoning (DR) navigation and positioning system composed of Fiber-Optic Gyrocompass(IXSEA:OCTANS) and Acoustic Doppler Log (ADL), fusion algorithm which utilize parts of heave compensation outputs of OCTANS and four speed sensor outputs of ADL is provided, available environment of the fusion algorithm is also provided. The simulation results showed that the fusion algorithm is more precise than the common DR algorithm and singer heave compensation outputs from OCTANS.
