OK, I'll give you that. But, how does it account for the rapid change in
slope, or the abrupt change for that matter? It doesn't look like an aging
crstal to me (maybe one with a problem that jumps in freq). For the most
part, there is no jumping DURING the slope, it seems to change on the
boundries. Would not switching satellites account for that?

Is it possible the phase shift is caused by the doppler of the satellite?
Not likely. Everything in this area is explained by the GPS receiver
having
a local crystal that isn't locked to a reference.
