Ah, well, ublox 6 is Galileo-ready and ublox 7 isn't as far as I can
see. But who knows when that'll actually make a difference. :-/

Looking again I, found their sales email address and gave that a whirl.
Keep you posted and possibly get back to you on your offer if it doesn't
work out. Thanks!

Nice idea. I have a number of PL2303-based ones floating around
somewhere which are well suited for the purpose, I gather. But I'd still
need a serial GPS receiver that works well indoors (so no SIRF chipset
but ublox 5/6/7). There aren't any providing PPS on the hardware list.
Do you know more than the list?

German manufacturer Gude (which also produces the DCF77 receiver I've
got) also has a GPS receiver:
http://www.gude.info/en/radio-time-systems/gps-time-receiver/expert-gps-clock-0508.html.
Since it's expressly advertised for time keeping purposes it should
provide PPS. But unfortunately it's got a SIRF-III chipset which most
likely won't work all that well in doors.
