Extract by Time File Format
Each extraction range consists of two values separated by commas: starting GPS time and ending GPS time.
The following table is an example of extracting range files by GPS time:
526494.500,527494.500
527494.500, 528494.500
527494.500, 528494.500
528494.500, 529494.500
529494.500, 530494.500
The above values can be stored in a text file (such as "extents.txt ") and loaded into the LiPowerline software.
