'Red Dot' meaning?

This morning I see a red-dot, few pixels, hovering/drifting about my "ME"-House location indicator.

It's 12 degrees(f) and I am guessing some ice on the outdoor little GPS dome. might be affecting the GPS coord's.
Sometimes, down at the bottom of the window, I see mostly 51 green ....other times this AM I see a lot of Red's and oranges.
Is that the cause or meaning of a Reddish orb hanging about?

Though I see all greens (GPS Sats) now and the Red Orb is a dozen miles NE of me.

hmmmm.
