Problem:
Attempting to import a DJI guest sensor flight into True View EVO results in an “error exporting Post Process Trajectory File” during the import process.
Probable Resolution #1:
Open the MRK file in an editor, such as Notepad++, and look for erroneous epochs at the beginning of the file which have a negative timestamp and GPS week.
Erroneous:
1 -259199.726026 [-522]…
Good:
2 332714.791783 [2191]…
Make a backup copy of the MRK file, then remove these lines from the MRK, and try the import again.
