Plateau STC


Things to figure out
What happens if we split the flights properly for oct 23
Looking at the pcn version of the site, are we seeing the same bruising?
Check for signal jumps due to the airports?
What's with the northwest section?
are we using the same KP

Newsstand review Aug14
There's been a bruising in the west, fixed, but bruising became present in the middle of the site
Merging flights and adding cors were tried
Released with issues since Paul wants the dataset asap
Normal looking flight (3 flights)
There's something weird shoe-looking in the position graph, and consistently, all APs had 2.8m movement
Points 1 and 2 are both on the north-west side of the site with cycleslips at 100%
Aug 14 is legit problematic
aug 14 weird point 1 and point 2.jpg

Aug 27
given that Aug 14 was released with bruising, let’s compare this instead to July 30

The comparison is fairly okay, but there’s really something weird in the west part of the site
This survey was released with issues as well as per Paul’s request

Sep 3
Used the correct comparison Jul 30 because Aug 14 and Aug 27 were released with known issues
There were super high surface differences for the GCPs and bruising in the east and west side of the site.
Looking at the GD step, the errors are very suspicious for the first processing run.

The high error GCPs are again, located at the northwest area of the site.

acfe65762e was also the KP used for the Aug 27 datasets, so basically, the GCP location can’t be the culprit, it’s actually the geotags that are struggling to align with this point that is fixed even in other surveys.

Sep 9
Was released without any issues and aligns well with july 30. There’s just bruising in the western but super faint.

Sep 18
used the same KP starting from august 27
Aligns well with the Sep 9 as expected.
was released as is, understandable since it’s been compared with immediate previous which had good outputs

Sep 23
Released with issues due to poor AP placement

October 2
Released without any issues, compared with Sep 18 which had good outputs.

October 9
Only had faint bruising but had high surface difference for acecbd1730 (KP)
New KP coordinates used
Had sudden jumps in the RMSE values of the PPK tags.



PPK Processing RMSE Checks
Only October 9 and Sep 23 datasets had the sudden jumps and poor RMSE values in the RMSE of the PPK tags.

The others look normal with less than 5cm RMSE values and do not have unusual jumps in the RMSE values
