Problem with "lsq" when processing RINEX2 files in 2025?

[chiyu-chiu]

Hi,

I encountered issues with some 1-Hz RINEX2 files, causing the PRIDE program to stop running during the "lsq" process.

I’m currently running PRIDE v3.1.2 with my custom configuration and have never encountered this issue before with similar RINEX2 files. I also tested processing older RINEX files from before 2025, and the problem didn’t occur.

Thank you in advance for your time and response.

Hello Chi-Yu,
The reason you are encountering this issue is that you have enabled the 2-order ionospheric correction. Our IGRF12 (which will be used when enabled the 2-order ionospheric correction) function is only valid up to 2025, but we have now updated it to IGRF14, which resolves this problem. To fix the issue, please download the latest version of the software.
