No resolution. I started graphing the epmp satellites visible and tracked. Visible is always above 7 with an average of 12.44. However the tracked dips down to 0 around 7-12 at night with an average of 6.93.
So what would make the GPS puck see the satellites but not track them? Why would it matter what time of day?
