Starting Nav processing

Raw data includes 2021 203b (#673). Processing together.

Error on import, following warning from IMU Data Continuity Checking:
WARNING: Gap of 3612.3290 seconds in CHECKDT input data

Assuming this is due to the IMU being off before take-off (as experienced in flight 2021 200), will skip import of first nav files.

Will use OS basestations:

  • ATTL
  • BUCI
  • NEWR
  • PETE
  • SNEO
  • STEE
  • WEYB

KING basestation did not have data available.

Nav Processing

This flight comprises of nav files Default151 - Default193. Will process 2021 203b (#673) data separately.

I think the gap in IMU data causing the above warning is between these flights.

Nav Processing

Ignore the previous comment. This flight comprise nav files of default.124 to default.149.

Base stations used:

  • ALDB
  • WEYB
  • SKEE
  • NEWR
  • ATTL
  • SNEO

SBET post processed nav file produced along with GQ report.

IMU lever arms used, reference to GNSS lever arm left as 0, 0, 0.

SBET Z RMS generally below 0.023m, on peak at 0.031m. X and Y mostly less than 0.015m.

Hyperspectral Processing

Processing all bands of all lines.

Creating Delivery

Have reprocessed all bands of all lines with new release of APL.

Logsheet generated.

Delivery created.

Need to create ReadMe.

comment:6 Changed 2 years ago by wja

Issue getting outflows of band 6 part 0 due to header size not matching file. Reprocessing this line fixed this.

Readme generated

Ready for delivery check

-Removed fodis directory
-Screenshots look good
-All bil file size OK and all bands mapped
-The data quality does not correspond with this year (not sure why, it is in the repo)
-Py6S is failing for some reason
-Fodis files not found, can't check the apl commands for now

comment:8 Changed 2 years ago by asm


-Py6S ran fine when connected through VNC, spectral shape matches. Fenix1k a bit low always below 700nm and a bit too noisy under 500nm but no spikes out of place.
Delivery awaiting now further corrections.

comment:9 Changed 2 years ago by asm


-Removed edges.txt file
-Updated data quality report
-APL commands run OK, the 3 band composite tiff files look a bit noisy, probably beacuse underflows.
With no other major issues, marking this as ready to be delivered.
