Doesn't support rtknavi

[ghost]

I'm trying to view the data the gnss-sdrlib gets in rtknavi but I'm facing a problem. After I press start at the rtknavi it doesn't display anything. It says "timeout" after few seconds then attempt to connect again. In the gnss-sdrlib log I can see it says "connection from 127.0.0.1" but still the rtknavi doesn't show anything.

Can you please help me with that?

Thank you

Hello.

1. In gnss sdrlib you'll need to select RTCM MSM output.
2. In rtknavi you'll need to setup input - rover (for example) / stream tcpip / localhost / port 9999 / format RTCM 3 !! . gnss sdrlib send RTCM 3 messages. (it was headache to understand this..)
3. rtknavi doesn't display number of sat & their SNR & etc until gnss-sdrlib doesn't calculate and send pseudoranges & etc, decode and send nav message with ephemeris and etc
4. you can view receive RTCM 3 MSM messages in monitor in rtknavi

I noticed that rtknavi will timeout if GNSS-SDRLIB hasn't managed to acquire any satellites. It's only after the GNUplot windows pop up showing a good correlation, that rtknavi will be able to connect. (Also check the RINEX output, to make sure there's more than just the headers.) Adjusting the Clock Error ppm setting for RTL-SDR seems to determine whether or not a signal can be received.
