<p>I let rtkrcv run for a while. I briefly was in fixed mode with 8
satellites. Tomorrow night I'll head to the county where I
usually get 10 satellites.<br>

<p>My setup is two OemStar receivers. One is connected via serial
port, the other is through a relay server and a 3g modem. I
removed the IP address of my server from the file and replaced
it with ip_of_server. The OemStars only support gps + glonass
(pos1-navsys=5). I think these are the only changes from the
stock conf file.<br>

<div dir="ltr">I can take mine outside tomorrow if the weather
holds and see how long it takes. IIRC it was 4 birds in the
sky and took a minute. I should have taken better notes on my
trials and tribulations to get it working since I am still
learning lots. I know at some point I had to set an approx
start location for the base station otherwise it would never
get to FIX from FLOAT. Even though conceptually it should. My
$0.02 is to use RTKNAVI first till you can get a FIX as it is
much easier to see what is going on. And then take your
working conf and use rtkrcv.

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....</p>

<div>I used the latest source for rtkrcv from
rtklibexplorer's repo and compiled it on my google
cloud instance. Also used my conf file I had working
in rtknavi since it had been tweaked for me. Here is
my setup. 2 CSG M8T boards, each connected to a
Raspberry Pi Zero W. They have str2str compiled and
streaming the data to the google VM of rtkrcv.
Attached is a screencapture of 3 terminals, 2 of the
PI and one of the rtksrv output stream of the rover
location. Sorry I blacked out the IP and location
info for security reasons. Right now the antennas
are in my window facing south so it is only a float
solution that comes and and goes. Not sure it
attachments will make it through the list....</div>
