+If the PPP processing method doesn't work and gives the error "Cannot fin epoch ... blah blah blah", then try this:
+ 1. Go to "Help" and "About GrafNav"

 === Exporting GrafNav Result to POSPAC ===
 It is possible to do the GNSS processing in GrafNav and then export the result into POSPAC. This saves doing the GNSS processing two times (one for LiDAR IMU and one for Applanix IMU). The version of GrafNav is newer than the POSGNSS version and should be used instead of POSGNSS.
 
-When the solution in GrafNav is ready to be exported, save the project and go into POSGNSS. Open the GrafNav project into POSGNSS, ignore warnings about being an older version. Then click the "combine GNSS" or "combine PPP" button. This will load in the previous solution. This can then be exported to POSProc as per usual.

If the "combine" buttons are not highlighted, then you can goto the menu and select combine solutions, select the files and load in the forward and reverse ones.
