 To do this in the config file set: {{{use_nav=false}}} in the section for the affected flight line.

+'''"There appears to be a non-numeric value in a specim time stamp SPTSMP message in the raw .nav file."'''
+
+The raw nav files, located in <project directory>/hyperspectral/fenix/*.nav, contain SPTSMP sentences (the ones that begin with "$SPTSMP"), which are timestamp records. Sometimes these sentences will contain non-numeric values, such as "$SPTSMP,207,4094+,1*38". Notice that the third record in this line contains a '+' character at the end of the number. This is what the error message refers to. To correct this, follow these steps:
+1. Login as arsf and locate the erroneous file.
+1. Change the permissions on the erroneous file using {{{chmod u+w <erroneous filename>}}} so that it can be edited.
+1. Locate the value with the spurious character and remove it. Note that this will '''always''' be in the second/third number(s) ('''non-numeric values in the first and last records of the sentence are fine''').
+1. Save the file.
+1. Revert the permissions to what they were before. If you used the command above, {{{chmod u-w <erroneous filename>}}} will do this.
+1. Make a note in the ticket saying what you did.
