    • doc_139: unexpectedly slew to 0 but then
    • doc_140: continue to track vessel heading.
    • doc_141: Since the vessel steams a very nearly
    • doc_142: constant heading, the resets were
    • doc_143: corrected for by taking the difference
    • doc_144: in headings before and after
    • doc_145: the reset and applying that difference
    • doc_146: as a heading misalignment angle.
    • doc_147: During 92/10/30-93/2/27 calibration
    • doc_148: values for heading misalignment and
    • doc_149: scale factor were obtained directly

    • doc_154: have not been calibrated. The
