An update regarding the GPS module, simply shielding it from air currents improved the things: http://www.flickr.com/photos/14336723@N08/8327229820/ 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. Il 2012-12-28 23:27 Fabio Eboli ha scritto:
Like I mentioned in a precedent message (answering Magnus) I'm seeing some temp effects on my GPS module, see this message: http://www.febo.com/pipermail/time-nuts/2012-December/073310.html
