[FOSS-GPS] Re: RTKLIB SKYTRAQ

[Ab_fab]

Hi all,

Thanks for sharing your findings.
FYI, I ordered and received on monday one Yuan10 USB dongle [1]

I made only basic testing so far, but my intention is to record raw data
and perform post-treatment, thanks to correction data network freely
available in France [2]
I expect to have 3 to 6 base stations available, nicely spread in all
directions, and in a range from 10 to 25 km.

The things I miss at the moment are spare time and a convenient open-sky
location (I live in a very dense urban area). But it's only a matter of
days / weeks of patience ^^

I'll let you know if / when I get interesting stuff

Bye
Fabien
