Navigation Processing

Basestation data converted to RINEX. All previous flights are also included in the basestation data, so just this flights data needed to be extracted (done with teqc).

GPS and GLONASS broadcast ephermides, along with precise ephemeris data accessed from CDDIS. PosPac could not access these itself.

Completed processing using the single base method. Also exported post-processed navigation data in ASCII format.

Flightline 6 failed with this error: 'Time goes backwards in navigation file' , this has been reprocessed without using the navigation file.

Owl delivery check

Started. Flightline 06 has incorrect geocorrection at one section please re-assess.

Owl Processing

Thanks, am trying to find a timing offset for line 6 (nav sync failure).

[wja]

Owl Processing

Timing offset of line 6 is ~3.1 seconds. However, there is what I think is a slight framerate error - there appears to be about ~0.1 seconds difference between the timing offsets across the flightline. I have not resolved this, however.

Recreated the screenshots for the delivery and put a data quality note in the read me document.

OWL DC

All checks have been run and passed. Please note that the mosaic screenshot in the readme is not complete. If this is by choice that is fine with me but otherwise might be worth updating. Once happy with this, the project is ready for zipping and delivery.

[wja]

Owl Delivery

Yes, sorry I should have mentioned, the screenshot in the readme is cropped, it was too large to include the every lines (includes lines from Grosseto project area and lines over the Siena airport, I just inlcuded the Grosseto area).

Thanks for the check, I'll start zipping the mapped data.
