empty solution file

[kolesar-andras]

Solution file contains only header, no data. I enable solution 1 output, choose type "File", stream is file://solution1.pos, format Lat/Lon/Height. File contains only header lines:

% (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

I start service, get some solutions but these are not added to output file. Do I miss something to set up or is it a bug?

I find the same question. I want to analyse the performance of the solution. But without data of position. I try it many times. little succesess most failure. it must be a bug.

@kolesar-andras

there are solution information in one pos file,but not in other 3 file. even though they are in same day and with almost similar settings.

Hi,

I've got the same problem: my .pos files are empty... Sometimes it works, sometimes not, depending on the phone I use. Did you find any solution?

Many thanks in advance.

Cheers,

Many monhts in the past, It seems few users have found this question.Maybe they mainly use the real-time function. And sorry, I don' t find the helpful solution to resolve it.

Hello, thanks for your quick answer! Unfortunately, I didn't find any solution despite a lot of research... I keep on searching!

You are welcome. Would you tell me what do you do by researching the RtkGPS? Do you want to analyze or modify the accuracy of the position like what I did? I ever  developed the app on the android studio, but it isn't helpful. I don't know how big bug on the app, if you are good at the java, maybe you can try it on the  android studio.

I am doing a comparison of the accuracy between commercial solutions and an open source solution using RTKlib. For that I need to access the raw positioning data, as we normally find them in solution.pos. But inexplicably, it no longer works even though it still worked a few days ago ... As I started the experiment with rtkgps +, I would like to end with it. But I know that there are other ntrip clients like lefebure who apparently work better: http://lefebure.com/software/android-ntripclient/ I'm unfortunately not that good at java, so it won't be a solution for me ;-)
