Key-Activities

1. Manage and maintain a global IGS real-time GNSS tracking network.
• Upgrade IGS stations to real-time. An emphasis will be placed on reference frame stations.
• Augment existing IGS network management procedures addressing the unique requirements of real-time infrastructure and processes.
2. Enhance and improve selected IGS products.
• For selected real-time stations, 1-second high rate, 30-second hourly and 30-second daily GNSS data files will be made available at IGS global data centers using real-time streams.
• High rate GNSS data streams will be made available to participants. An emphasis will be placed on ultra rapid ACs to assist in their efforts to reduce the latency of the ultra rapid products.
3. Generate real-time products.
• IGU predicted orbits will be made available in real-time.
• Real-time ACs will generate real-time GNSS clock information. A strategy for combining these solutions will be investigated.
4. Investigate standards and formats for real-time data collection, data dissemination and delivery of derived products. Formats including RTCM 3.0, BINEX and RTCA will be investigated. The objective is the development of an open standard that will meet the needs of a future IGS Real-time Service. This objective will be pursued during the pilot project through the work of the RTWG. GNSS standards organizations such as RTCM (SC 104) will be consulted and encouraged to address the needs of the IGS community.
5. Monitor the integrity of IGU predicted orbits and GNSS status.
6. Distribute real-time observations and derived products to real-time users. Both the RTIGS and the NTRIP protocols will be assessed for this purpose.

7. Support Network DGPS/RTK
• Encourage participants who operate DGPS/RTK to use IGS real-time streams in their networks.
8. Encourage cooperation among real-time activities, particularly in IGS densification areas.

Many applications have been using IGS and EUREF real-time GNSS data streams and have been tabulated at BKG since February 2008.
