Could you please share your GPS param file for OAKBAT dataset?

I have tried, but the I/Q plot (discrete time scatter plot) does not look right. Did I do this correctly?

If you don't mind, could you please share your GPS param file for OAKBAT dataset?

Can you share your own file so that we can check if you have set the right params or not

thank you. L109 ~ 115 are the area that I think we need to fix a bit.

您能否共享自己的文件，以便我们检查您是否设置了正确的参数

谢谢。L109 ~ 115 是我认为我们需要稍微修复的区域。

I have recently been working with the same receiver to process the OAKBAT dataset. Following the parameter settings provided for the TEXBAT dataset, I only changed the sampling rate and loop bandwidth. However, I encountered the same tracking issues as reported.

Could you please let me know if you have found a solution to this problem? I would greatly appreciate your assistance.

Thank you very much!!

Hi! Tortuga,

Just by looking at the tracking plots, I do not see any particular issue with the receiver's tracking. There is indeed some spikes in the position deviation, which should not be there in nominal outdoor condition. As a minimum, you can smooth out the position deviation with some averaging filter.
Good luck!

Hi Zahid,

Thanks for your reply. I’ve figured out the issue I had with the distribution in the upper-left IQ plot. Normally, the IQ plot for GPS L1 signals should show two circles, but I observed three. After analyzing, I found that this was due to issues with the signal quality in the initial segment. I bypassed the first 15 seconds of the signal and reprocessed it, which resolved the issue and everything returned to normal.

Thank you again for your help!

Best regards,
Yili Song

Hi! Yili,

Great that you solved the problem yourself. It is always recommended to skip few seconds of data if possible. However, I processed a short portion of data with your configuration file, and got an expected result. Please see the ENU deviation result for your reference.

Good luck!

Best Regards

Zahid
