  • Page 7: Foreword

    A Word to the Owner of the SC-50 FURUNO Electric Company thanks you for purchasing the FURUNO SC-50 THD Satellite Compass. (Hereafter, for sake of brevity, we refer to the SC-50 as Satellite Compass.) We are confident you will discover why the FURUNO name has become synonymous with quality and reliability.

  • Page 8: System Configuration

    SYSTEM CONFIGURATION The SC-50 consists of an antenna, a display unit and a processor unit. The tri-antenna system accommodates three antennas/receiver units and is available in a low-profile radome type or open type. The tri-antenna system helps reduce the influence of ship's motion (rolling).

    Difference in range between A1 and A2 is ∆λ + nλ where λ is 19 cm. “n” is automatically found during the initialization stage by receiving three satellites. A fraction of a carrier wavelength, ∆λ, is processed by FURUNO’s advanced kinematic technology in geographical survey, thus determining a vector (range and orientation) A1 to A2.

  • Page 82: What Is Waas

    APPENDIX 7. What is WAAS? WAAS, available in North and South America mainly, is a provider in the worldwide SBAS (Satellite Based Augmentation System) navigation system. SBAS provides GPS signal corrections to SBAS users, for even better position accuracy, typically better than three meters.
