[time-nuts] Strange GPS behaviour

[Fabio Eboli]

An update regarding the GPS module,
simply shielding it from air currents
improved the things:

At 48000s I swapped references, hence
the change in slope.

I think the poor receiver module
(Azelio, 20€, I think it can be
considered cheap :) is not to be blamed
too much, I mounted it raised  from the PCB,
and the only thermal contact were the few
pins used to connect to it, and it was
exposed to moving air.
But usually it will be sodered directly
on the PCB like an SMT component, and
enclosed into a box.
