I recorded the following fixes with my GPS on our flight which should be at the mid-time of the two minute averaged sights:
19:32:20 Z 34-12.468 N 119-10.657 W
19:39:01 34-11.094 119-10,212
20:18:04 34-12.785 119-11.267
20:27:59 34-12.183 119-11.223
20:34:02 32-11.638 119-11.672
I have attached six files. The .txt files have the recorded GPS data. There are two lines for each data point (see sample below) and each line has the time in the second group, Zulu HHMMSS.sss of each line. (18:51:19 Z in sample)
Then comes the latitude, DDMM.mmmm N, (34° 10.6086' N) and the longitude, DDDMM.mmmm W (119° 07.4245' W) which is repeated in the second line.
The altitude is in the tenth group in the first line of data, (938.0, M (meters))
The ground speed in knots is in the eighth group in the second line (102.00).
The tenth group in the second line of the data is the date, DDMMYY. (090110.)
$GPGGA,185119.000,3410.6086,N,11907.4245,W,1,08,00.0,938.0,M,00.0,M,,*76
$GPRMC,185119.000,A,3410.6086,N,11907.4245,W,102.00,0.00,090110,,*19
You can open the txt files with wordpad or similar.
This was recorded by a gps data recorder used to tag digital photos with location information see:

I also output the data in KML format.
The .kml files open up in Google Earth and show the flight paths.
