1	The International GNSS Service --Progress Towards Real-time Mark Caissy Chair IGS Real-time Working Group http://igscb.jpl.nasa.gov/projects/rtwg/index.hml
2	Outline Vision and Goal Where We Are Today Current Activities Emphasis and Next Steps CORS – Things to consider
3	Vision for the Future The availability of IGS data and products in real-time via IP communication links (open internet) Enabling real-time Precise Point Positioning globally at the decimeter level or better Globally consistent ( seamless / no RF issues ) An enabler for a multi-disciplinary community
4	IGS Real-time Initiative Goal To develop real-time infrastructure and processes To deliver real-time data to analysis centers To make available real-time data and products to real-time and nrt users
5	Where We Are Today Designed developed and implemented a prototype real-time network Defined message formats and an exchange protocol (UDP / Types / IODS ) Developed software tools for transmission, reception and integration of real-time data Real-time data distribution trials have begun and real-time products are under investigation
6	RTWG Software Tools UDPRelay: Routes data and products to analysis centres, archival centres and end users. Archiver (RTIGSA): Archives RT-IGS observation data. Saves and forwards Multicast Receive (RTIGSMR): reads and decodes RTIGS data messages Data source is an archiver or relay
7	Prototype Network
8	Data Distribution Trials udpRelay JPL, GFZ, NRCan, ESOC, GA, IEN, COSMIC RTIGSA NRCan, CDDIS, BKG, UCAT, NOAA -- Space Environment Center, TUV RTIGSMR TUV ( IGU – predicted quality assurance )
9	Performance Monitoring --Data Availability 24hours on 05/04/20
10	Performance Monitoring --Data Latency 24hours on 05/04/20
11	Emphasis/Next Steps Phase 1 -- Data Pilot Project Increased reliability of data for nrt and rt applications – redundancy in data delivery 100% availability of nrt data produced at remote stations Network Management Increased characterization of network performance Grow the network
12	Recommendations to CORS Data formats All observables must be provided Managing Change Real-time users must be aware of a change in real-time
