Data location: /users/rsg/airborne/2023_arsf_data/flight_data/italy/SwathS_23-2023_147_Grosseto

Data arrived from NERC-ARF via hard drive September/October 2023

PI: Martin Wooster

Sensors:
Fenix1k (requested, flown)
IBIS ( main requested, flown)
OWL ( requested, flown)

Final checks - warning about the real time navigation time stamps was flagged.

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.

[wja]

Exported post-processed navigation data in ASCII at collaborator's request.

[jann]

Radiometric calibration completed, waiting on boresight.

Owl Delivery Check

• There were some aux.xml files in the delivery, have removed these.
• Looking at the outputs of check_apl_cmd looks like the timing of some of the lines are a bit off, line 24 is probably the worst. Isn't really bad (couple of pixels) but worse than normal. Might just be something to flag in the readme or delivery email.
• There is a line 30 in the 1b data but there isn't a navigation file, mapped data or screenshot for it.

Everything else looks OK.

Owl Delivery Check

Looks like the poorer geoaccuracy is limited to the lines at the maximum viewing angle (35 degrees). Looks like a pitch error so worth double checking the boresight used for these lines:

• 6
• 7
• 10
• 11
• 23
• 24
• 27
• 28

Owl Delivery Check

Have also added view angles to logsheet.

Owl Delivery Check

Lines with the 35 degree viewing angle has the wrong boresight. Reprocessing.

[wja]

Owl Processing

Four lines are missing: 31, 32, 33 & 34. Will run radcal now.

Line 30 failed to map because of the "time goes backwards" issue - navsync has failed. Will force this can see if there's much of a timing error.

[wja]

Owl Processing

Line 30 accuracy looks fine with the forced nav. Added to delivery.

Lines 31 - 34 are processed to level1b. But are failing beyond this... bad magic number in 'data_handler': b'\x03\xf3\r\n'

[wja]

Owl Processing

Lines 31 - 34 now processed. Line information XML needed re-doing for line 30. All added to delivery.

Zipping mapped files. Marking ready to deliver.
