[FOSS-GPS] RTKlib help pls

Tue Nov 19 17:37:59 PST 2019

I gave rtkrcv a try from https://github.com/rtklibexplorer/RTKLIB demo5 
branch and voila, I get a float solution now!  No more no 
double-differenced residual after 7 weeks of struggling!  Thank you so 
much for pointing out rtklibexplorer.  Now onto getting a fixed 
solution.  Any idea about how many valid satellites are required for a 
fixed solution?  I'm getting 7 right now in the city, overcast....

# of satellites rover       : 11
# of satellites base        : 10
# of valid satellites       : 7
