Started Nav Processing

See #672

[wja]

Nav Processing

Will process this separately to #672, I believe there is a gap in the IMU data between the two flights on this day. The nav files specific to this flight need to be identified and imported to POSPac separately.

[wja]

Nav Processing

This flight comprises of nav files Default151 - Default193.

OS Basestations used:

• BUCI
• NEWR
• PRIS
• SNEO
• STEE
• WELL

SBET and QC report exported.

RMS of SBET shows X Y Z values below 0.026 m
Z generally between 0.013 - 0.021 m. X & Y generally between 0 - 0.013 m.

[wja]

Nav Processing

Have reran the SBET generation with lever arms for GNSS to reference as 0. lever arms for reference to IMU are the values previously used (distance from GNSS to IMU).

RMS of SBET has increased, but still looks reasonable. Z between 0.025 - 0.045m (with one spike at 0.09). X & Y generally less than 0.025.

Delivery Ready for Checking

[asm]

Delivery Check

Started.

[wja]

PI notified delivery will be on FTP slot 5 once checks are finished. Update to be sent tomorrow (Tuesday 21 Dec)

[asm]

DC

-Flightlines look good with nice overlapping areas
-Removed fodis dir and edges.txt file
-There are a lot of underflows but data spectral shape matches with Py6S. Fenix1k a bit low always below 700nm and a bit too noisy under 500nm but no spikes out of place.
-All other checks have been run and everything is looking good
Will start zipping the lines
