"For some reason it will use 1980 as the year and also the wrong month, and sometimes wrong day"
GPS time is a count of the number of weeks, and seconds of the current week, since an epoch. The start epoch was 0 hours (midnight) Sunday 6-Jan-1980, when GPS time was 0.
When a GPS time message is corrupted, truncated, or wrongly interpreted, it leads to incorrect timestamps. This can happen for a lot of reasons.
As for how to prevent it from happening with the P4RTK, I don't have any magic bullets. It may be that you can suss it out by looking for patterns in the manner in which the TOFO stamp is wrong.
Due to CoVid, I don't have access to our P4RTK to test myself. This may change in the coming weeks or months. That being said, I haven't used PPK on our P4RTK, only RTK w/ NTRIP.
I know this probably doesn't help much, but at least now you know why you keep going back to 1980. |
