[knpa]

We are currently awaiting Basestation data from Thomas Schmid.

[knpa]

We have received the data referenced above.

[knpa]

Beginning LiDAR processing.

[knpa]

Completed IPAS processing.

Unfortunately result was is less than satisfactory for the first flightline, where the arsf basestation loses it's fix. This could be not improved upon by adding the permanent basestations. The 1-second data from the permanent stations are unavailable for this day apart for SONS (which is a little way away).

[knpa]

Slight horizontal discrepancies which looked like it was caused by a pitch error.
Changed pitch from -0.00324419 to -0.003 which fixed the problem.

[knpa]

This flight suffers from roll error. It is not particularly severe though: there will be a vertical error of approximately 10cm at the edge of the swath width.

The roll discrepancy is not constant between flightlines so will not attempt to correct. Unsure if the error is random. Early flightlines have a positive roll discrepancy but this then seems to switch to negative by the fourth flightline.

[knpa]

The first cross line (14:33) has a large discrepancy with other lines - approximately 45cm.

[knpa]

There is a lot of noise for this flight.

Finished QC, preparing delivery.
