GPS navigation was fed to the acquisition system every second by the Trimble Centurian P-code Receiver. The raw navigation contained on this CD-ROM is the original navigation extracted from the SEG-Y headers and does not contain, the year or Julian Day. You may access the raw navigation by the links provided below, or the files can be found in the subfolder RAWNAV inside the NAV folder at the top level of this CD-ROM. All the files are stored as flat ASCII files, with .TXT extensions. In order to comply with ISO 9660 standard naming conventions tracklines d118_1860, d118_1812, and d118_1840 have been shortend to d1806, d1812 and d1840 respectively.
