About the Ground truth and size of the model data

[XUEYAN9]

Dear author,
Good evening! Sorry to bother you.
I am very interested in the DPE and I've studied and tested the code and theory.

I have two requests about the demo data:

• [1 ] could you tell me the Ground Truth about the data?

• [ 2] Because I find the data just 4.71s,but not 45s as said, so the data is too short to do the test. could you give me longer data to test and study the code and algorithm?

Thanks a lot.
I am looking forward to your reply

Best Regards,
xueyan

Hi Xueyan,

I have tagged the paper/code author in the issue. Unfortunately, he graduated 2 years ago and so might not be able to respond quickly.

I don't have all the details, but I believe that the data on the repo is just a small sample for testing (static receiver, NI GNSS simulator) whether the code properly runs on the system. You should be able to run the code with any other .dat/.bin signal file acquired from a GNSS simulator or receiver.

Best,
Shubh

Dear author,

I hope this email finds you well. I am writing to you because I have recently been researching DPE (Differential GPS Positioning Estimation) and came across a paper that mentioned your tool, pygnss. However, I have encountered some issues with the provided example files, which seems to be hindering further analysis.

Firstly, I would like to express my gratitude to you and your team for developing the pygnss tool. It has provided a valuable platform for GPS data processing, and I have a keen interest in your work.

I was wondering if it would be possible to provide some additional instructions or alternative data that I could use to further test and validate the functionality of the pygnss tool. If there are any other datasets or sample files available, I would greatly appreciate access to them.

Thank you very much for your time and assistance. I am looking forward to your response.

Best regards,
