Navigation processing started, basestation ppp results:

Lat	51 24 15.45178
Long	-1 30 50.16899
Ell. Height	183.434

[stgo]

Solution using ipas honeywell is poor, will continue trying to improve it but I'm going to process the alternate navigation at the same time to see if that is better.

[stgo]

Got 10 cm or less position accuracy on the flightline area using ipas honeywell.

[stgo]

Initial inspection of the flightlines indicates a uniform roll error. Testing the first 4 lines with new values.

Starting Fenix processing

[benj]

There are fifteen lines in the logsheet but only ten Fenix data files (and line 10 has a raw file but nothing else). Instrument may have failed.

[benj]

...actually they are all there, just the file numbering is slightly confused (logsheet says the instrument crashed, I assume hence the slightly messed-up numbering and presumably the extra partial raw file).

[stgo]

Values used for lines 104713 and 110158:

Roll	-0.004001414
Pitch	0.00113716
Heading	0.00056484

[benj]

Fenix data do not contain dark frames. We had hoped to use dark frames from a different flight (similar to what we did for VOCALS in 2009) but looks like this is not a valid approach for Fenix at least. Checked dark frames from day 2014-152a (some of which have the same settings) and the dark frames vary by a factor of 3-4, so cannot say what the appropriate dark values to use for these flights would be. Marking Fenix blocked until we come up with another way to deal with that (if we can).

[stgo]

Currently checking to see if there is in fact a variable roll error or if I was just over confident with my values for 104713 and 110158.

[stgo]

Values for 104713 and 110158 are not applicable to other flightlines, 111834 on to 120318 use -0.003918414. will continue getting values.
