  • Page 12: Principle Of Operation

    STD 21 GPS Principle of Operation The Raytheon Marine/Anschütz STD 21 GPS compass uses continuous carrier phase measurements of two GPS antennas aligned to the ship‘s longitudinal axis for relative positioning. Relative positioning means that state of the art algorithms exploit the carrier phase measurements and the broadcast satellite ephemeris for precise computation of the baseline vector pointing from the aft antenna to the fore antenna.

  • Page 13: Scope Of Delivery

    Satellite Compass STD 21 GPS STD 21 GPS The GPS L1 carrier has a wavelength of 19 cm which is much smaller than the 100 m chip length of the modulated C/A (”Clear Access”) pseudo--random noise code used for GPS satellite positioning. Thus, obstacles of correspondingly small size disturb the heading determination process.
