      I’m developing a data logger on an M5Stack CoreS3 SE.
      My GPS is the M5Stack GPS Module v2.0 with ATGM336H-6N (AT6668) and I log data at 10 Hz.

      Once the vehicle speed drops below 30 km/h (~20 mph), the latitude/longitude start to “jump” every few samples.

      I suspect the low-pass filter settings may be the root of the problem—are there any work-arounds or alternative settings that can mitigate this?

      Also, if anyone has encountered similar cases, I’d love to hear about your experience.
