Unpacking Checks

Raw applanix data appears corrupted (along with 186b). Callum reported that there are errors with the unit writing via USB so had to resort to ethernet.

No issues flag with old IPAS system (on adjustable Owl mount) at this point.

Nav Data

We recieved this flight's data too late to access basestation data from the OS's FTP. I have put a request to BIGF to access 30s RINEX data for the following stations (which cover the start / end times recorded in the Owl headers).

  • PETE
  • SNEO
  • NEWR
  • STEE
  • ARDL

  • ARDL
  • ATTL

Along with broadcast ephemeris data.

BIGF will need acknowledging in data delivery.

Nav Processing

Completed for IPAS20 IMU (only to be used with Owl data).

Position separate in the Z axis was slightly high for a period at ~0.075 m. The position accuracy for the X & Y axes are high, at ~0.06 m.

Creating Owl Delivery

Delivery needs checking

Delivery Check

  • Readme looks good
  • check_apl_cmd ran through OK
  • check_bil_size.py didn't result in any errors.
  • Alignment between lines looks good. There is some distortion around the buildings at Duxford which might be fixed using a higher resolution DEM. We do have a LiDAR one so perhaps mention this when delivering.
  • Project code needs changing in line_information xml files.
  • Looking at the level1b masked files there seem a lot of pixels masked out when checking the spectra, can't remember if this is what we normally expect for Owl though.

After check of masking and fixing project code in XML good to go.

Ready to Deliver

XMLs updated. Masking is comparable to 2018 lines.
