    4222 The following screenshot shows the encoding and uploading of a stream of precise orbits and clocks coming from a real-time network engine in 'RTNET' ASCII format. The stream is uploaded to Ntrip Broadcaster 'products.igs-ip.net'. It is referred to APC and IGS08. Uploaded data are locally saved in SP3 and Clock RINEX format. The SSR Provider ID is set to 3. The SSR Solution ID and the Issue of Data SSR are set to 1. Required Broadcast Ephemeris are received via stream 'RTCM3EPH'.
