They are pretty good, being dirt cheap nav receivers. In this plot, it is identical to the MC-1010 (same reference design, same firmware). http://cm.kasperkp.dk/mc1010ga.png (adev of various) http://cm.kasperkp.dk/mc1010p.png (phase, fei5680) The MC-1010 is using the 3339 chipset, and is GPS-only. The MC-1010-G has the 3333 chipset, and is GPS+GLONASS. When testing, try fast temperature shifts; I found that it would shift the PPS much more than I expected, as if there is a rather slow filter driving the PPS output. > > Have another trick up my sleeve but need a Linux kernel hacker.

If it is not too complicated, and interesting, shoot me a mail directly. I reserve the right to decline, and the right to give up:-) /Kasper Pedersen _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
