The Navigation Data Includes:
All navigation files are stored as flat ASCII text files. The raw navigation files are stored in the RAWNAV subfolder of the NAV folder at the top level of the CD-ROM. These files have not been edited and do not have year or Julian Day written in the record. The edited navigation files are stored in the EDITNAV subfolder, and the 500 shotpoint interval files are stored in the SHOTNAV subfolder, both of which are located in the NAV folder at the top-level of this CD-ROM. Both the edited navigation and the 500 shotpoint navigation have year and Julian Day added to each record.
Note: The shotpoint navigation provided in this report has not been corrected to reflect the 20 m offset of the source to the GPS antenna.
