Example 1:

Task:

Generate a real-time stream with legacy RTCM 3 messages generated from a SSRZ data stream.

Job Details:

 ssr2obs in combination with GPPNET

Example 2:

Task:

SSR2OBS with the use of transformation options. The OSR corrections are defined in the service CRS of the SSR generation, i.e. typically current epoch of the latest ITRF realization. Use a 15 parameter transformation to convert to the datum requested by the user application e.g. an ECEF.

Explanations:

    

Example 3:

Task:

A typical start of SSR2OBS reads as follows

Job Details:

    start bin/ssr2obs.exe +syst -o=- -i=%GGA:PORT% -z=%Caster-IP%:%Caster-port% -N=%Stream%,%User%:%PW% -pid=%ProviderID% -sid=%ServiceID% -eph=%EPH_SOURCE% -rdist=0.0 -ro=0.3 -re=0 -rtcmmsm

Explanations:


Example 4:

Task:

Start SSR2OBS without SSR_IN with integrated SSR_IN option in SSR2OBS.The command expects RTCM-SSR/4090.4/4090.5 messages and provides legacy RTCM. The Geo++ 4090.4 and 4090.5 are only available using GNSMART1 (GNNET) and the support is fading out in favor of the Geo++ SSRZ format.

# -ro[=]x.x - output offset to last GGA [0.8]
# The output of legacy RTCM corrections (see option -rtcm) is
# triggered to be 0.8 after receiving the NMEA GGA string. This
# option can affect the GNSS rover prediction algorithm as the delay
# of the actual timing can be kept small.
# The option can be combined with option -re.
