Navigation Processing
I mistakenly thought this flight was the York flight initially and only downloaded OS basestation data for there. These are no longer publically available.
However, NERC BIGF has provided us with Alconbury basestation data (note that SNEO, the closest station was not operating on this date). Station data we have is below:
- ARDL
- ATTL
- NEWR
- PETE
- SKEE
- STEE
- WELL
- WEYB
NERC BIGF will need acknowledging for any deliveries from this flight.

Processing complete. SBET and QC report exported.
Quality looks good.
Have used lever arms:
x | 0.154 |
y | 0.170 |
z | 1.377 |
IMU offset by 180 rotation (Z axis) on export.

Hyperspectral Processing
Starting Fenix1k boresight.
Have made a DEM and config file.

Hyperspectral Processing
It appears that lines 1 - 13 have x2 VNIR & x1 SWIR spectral binning whereas lines 14 - 17 have x8 VNIR & x1 SWIR binning.
Updated header wavelengths to calibrated wavelengths.

Fenix1k Boresight
Best lines identified for boresight calculation:
- Pitch: 8.0 & 9
- Roll: 4 & 7
- Heading: 5 & 7

Fenix1k Boresight
There's some sort of timing error in at least some of the lines.
The 2023 193 York data appears to have a consistent 0.04 second offset... this value isn't correct here.
Investigating.

SCT offset appears to be consistently +0.06 with lines with big 'wobbles' where it's more visible (lines 1, 2, 5, 10). Will apply this to all bands and boresight.
Note this is larger than the 2023 193 York flight. Need to keep an eye on this.

Fenix Boresight
The following boresight offsets look good:
Pitch | 0.45 |
Roll | 0.10 |
Yaw | 1.50 |

Fenix1k
Have updated swath mask (to account for edges being obstructed).
Unpacking
There is no Ibis data. Unsure if it was flown or not.
