I flew PH for the first time this morning. It held position very well in a pretty stiff breeze. You can playback the logfile in the GCS. On the Flight Data screen, at the bottom right of the screen "Connections:", select "Logfile: Logfile Replay" and "Connect" Then select the logfile attached.
In the upper right corner of the map click on the UAV symbol and select "center map on UAV" then you can zoom in to see the GPS track, the PFD, Flight Mode" etc
