I just got an ultimate gps from Adafruit and am reading the GPS data from it with a valid fix with an external gps antenna plugged in.
It’s sitting on the desk next to me, but I’m noticing that the direction and speed are constantly changing. The course will jump 100 degrees in an instant, then be +/- 10 degrees of that reading then make another massive jump. The speed is constantly reading just under 1 knots.
It is using the PA6H GPS chip and I was curious if anyone else has had issues with the GPS or if this is expected behavior for this GPS? (I’ve asked this over on adafruit’s forum as well, but figured the people over here might be just as familiar with this GPS chip)
