    • doc_136: exhibited resets , where it would
    • doc_137: unexpectedly slew to 0 but then
    • doc_138: continue to track vessel heading.
    • doc_139: Since the vessel steams a very nearly
    • doc_140: constant heading, the resets were
    • doc_141: corrected for by taking the difference
    • doc_142: in headings before and after
    • doc_143: the reset and applying that difference
    • doc_144: as a heading misalignment angle.
    • doc_145: During 92/10/30-93/2/27 calibration
    • doc_146: values for heading misalignment and
    • doc_147: scale factor were obtained directly
    • doc_148: from bottom tracking each trip.

    • doc_152: have not been calibrated. The
