TinyDuino Processors & TinyShields / Strange issue with Tiny GPS
« on: July 05, 2023, 03:28:52 PM »
Hi,
I am working on a GPS logger. The data is logging and writing to an SD card and everything is well and good in that regard.
The issue i am encountering is that the Latitude is repeatedly jumping around, but the Longitude is always correct. I am Seeing the latitude numbers jump from 45.0xxx to 45.5xxx and then also throwing in random groups of 53.9xxx. the 45.5xxx is correct but most of the data is logging at the 45.0xxx locations. The pattern of points matches how i'm walking around with the GPS during tests but i can't seem to rectify the issue with it wanting to log a bunch of points with the wrong latitude values but always the correct longitude. I am walking around in open areas with fine GPS reception on a Survey grade unit so the location shouldn't be the issue. It has been turned off and on many times, i tried leaving it in a single location for 10 minutes before walking it around to see if that helped and its the same.
Anyone else ever experience this? Anyone have any ideas as to what could be causing this?
Thanks!
Brandt
