Can someone point me to the documentation for the LLH data stream from the Reach Rover? What is the format of this message? I can see that the first 4 messages are time, lat, Log and Height. What are all of the other data fields?
Thanks.

Take a look at the RTKLIB documentation, it should be specified there.
Hello,
I can not find what the LLH output means in the http://www.rtklib.com/prog/manual_2.4.2.pdf
Does anyone know what those fields means when on Reach config_page the LLH is chosen as output (tcpsvr Solution output format):
What I get:
1890 464306.800 58.990662423 14.265681149 66.5928 2 10 0.0112 0.0073 0.0162 0.0037 -0.0044 -0.0045 1.80 1.1
Thanks!
Hi,
You should check the first lines of the output file.
I did a solution log for LLH and received the following:
% (lat/lon/height=WGS84/ellipsoidal,Q=1:fix,2:float,3:sbas,4:dgps,5:single,6:ppp,ns=# of satellites)
% GPST latitude(deg) longitude(deg) height(m) Q ns sdn(m) sde(m) sdu(m) sdne(m) sdeu(m) sdun(m) age(s) ratio
1891 387224.400 48.407847411 11.462107573 450.3788 5 6 7.9698 3.2557 14.1180 -4.0982 5.4390 -9.8588 0.20 0.0
Should be this:
$POS,week,tow,stat,posx,posy,posz,posxf,posyf,poszf
week/tow : gps week no/time of week (s)
stat : solution status
posx/posy/posz : position x/y/z ecef (m) float
posxf/posyf/poszf : position x/y/z ecef (m) fixed
but it seems to be modified…
1890 464306.800 58.990662423 14.265681149 66.5928 2 10 0.0112 0.0073 0.0162 0.0037 -0.0044 -0.0045 1.80
week/tow ? lat long heigth Q …
1.1
Thank you!
To conclude, what this data “1890 464306.800 58.990662423 14.265681149 66.5928 2 10 0.0112 0.0073 0.0162 0.0037 -0.0044 -0.0045 1.80 1.1” means is:

Where did you get the ECEF message format? I cannot find that on any documentation.[quote=“guenter, post:4, topic:1354”]
week/tow : gps week no/time of week (s)
stat : solution status
posx/posy/posz : position x/y/z ecef (m) float
posxf/posyf/poszf : position x/y/z ecef (m) fixed
