Data location: /users/rsg/airborne/2023_arsf_data/flight_data/italy/SwathS_23-2023_148_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)

OWL: Some lines don't have nav data, these are data recorded of NASA JPL's blackbody when the aircraft was stationary on the runway.

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.

Owl Processing

Processing all files to level1b and flipping samples (will confirm if this is the correct configuration for this (IOP 1) installation).

Owl Processing

Some notes:

• This is a huge flight!
• Some lines are not on the logsheet (33 to 44) and do not have navigation data. These are most likely taken on the runway over JPL's blackbody for calibration.
• All remaining 32 lines with navigation data have nav sync in headers
• Line 15 has 8 dropped frames. All other lines are low.

Owl Processing

All Owl lines processed to Level1b (includes blackbody data when the aircraft wasn't moving).

Mapping 3 bands of Owl and Fenix1k to verify the installation parameters (IMU + sensor rotation, boresight, lever arms etc).

[wja]

Owl Processing

Confirming that both Italy installs require no flipping for the Owl in order to map. The instrument was installed backwards, but so was the IMU.

Will add a summary of each installation and what data needs "flipping" to the processing documentation.

Fenix Processing

Replaced header wavelengths

Fenix & Owl Processing

Have been using this flight to verify the processing chains are working as they should and whether data needs flipping.

Have added a summary of things to know for each installation here: ​https://nerc-arf-dan.pml.ac.uk/trac/wiki/Procedures/installation_summary_2023

Owl boresight is required to continue.
