Dear author,

Good morning!Thanks a lot for your sharing!

I have two requests:

First, Could you give me a Ground Truth about the data? I search the site on Google Maps, but I can not sure of the accurate position.

Second, the data you provided just 4.78s, but not 45s as said. We can not use the short demo data to test the code, Because the scalar can not work well with the short data. Could you help to upload a little long data?

Thanks a lot.
Looking forward to your reply!

My name is Sergio, and I am a Ph.D. student at The Hong Kong Polytechnic University. Together with Dr. Bing Xu, I am currently researching Direct Position Estimation GNSS receivers and found the PyGNSS code the Stanford Navlab team has developed to be very useful and versatile.

However, we are currently having trouble getting acceptable positioning results from both open-sky and urban environments. We were astounded when the positioning error is even larger compared to the conventional two-step GNSS receivers. I'm wondering if you can shed light on this matter.

Thank you!!

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,

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

Hello, I always encounter errors when running pygnss. Could you please provide more datasets along with their descriptions? I'm looking forward to your response.
