Good. What model GPS? From that I can tell the number of channles

So every time the receiver has to guess what sats may be in view, and
start to search for them.

There have been a lot of changes in how gpsd reports data from a GPS
without a fix. So I expect you to see differences in the "No FIX" state,
but not in the "2D" or "3D FIX" state.
To compare, you can always just grabs the data from the serial port
directly and remove gpsd from the equation.
