Dear All ...

I start playing with rtklib.
Source code is taken from : https://github.com/tomojitakasu/RTKLIB.git
My GPS Module is based on NEO-6M, yes I knew that 'by defaults' it will not
throw raw output.

I read from openstreetmaps wiki, and make the osmap.cmd file contain only:
!HEX b5 62 09 01 10 00 c8 16 00 00 00 00 00 00 97 69 21 00 00 00 02 10 2b 22
!HEX b5 62 09 01 10 00 0c 19 00 00 00 00 00 00 83 69 21 00 00 00 02 11 5f f0

Since I only have 1 receiver, I need to multiplex it's output so that
multiple application can 'hear' it.
str2str -c ./osmap.cmd -in serial://ttyUSB0:9600:8:N:1:off#ubx -out
tcpsvr://:9000 ubx

Ntrip Caster is BKG standar NtripCaster 0.1.5/1.0
To stream that ubx output to my ntripcaster, from other terminal :
./str2str -in tcpcli://127.0.0.1:9000#ubx -out
ntrips://:sesam01@ntrip.bno:2101/BINO rtcm3

And for simulate attached receiver for rtknavi, i use :
./str2str -in tcpcli://127.0.0.1:9000#ubx -out tcpsvr://:9001 ubx

I test my ntripcaster using ntripclient taken from
https://github.com/nunojpg/ntripclient.git
ntripclient -m BINO -s ntrip.bno -r 2101 -u bino -p 1234 -M 3

And the result is at : http://oi68.tinypic.com/2i7y7fr.jpg

Know, RTKNavi have a bunch of configuration.
Currently I have ntrip caster and virtual ublox stream at port 9001.

How to test those system using rtknavi ?
I read and try to follow rtklib manual page 7 and up ... but still :
1. Got no solution, and
2. Don't know what to look/fix

Sincerely
-bino-
