    6 Base station data not 1 second resolution?  Resample (interpolate using posgps).  While this doesn't improve the data, it apparently makes it more evenly applied (no internal interpolation?).  Unverified.

    6061When 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.
