  1. IGS Real-Time Service Meeting the Needs of the IGS Real-Time PPP User Community Mark Caissy (NRCan), Loukis Agrotis (ESA), Georg Weber (BKG), and Steven Fisher (JPL)

  2. Introduction to the IGS Real-Time Service (RTS) Redundancy in the production chain Accuracy of the products Interest since the launch Summary Outline

  3. Large global network 150+ stations Compelling redundancy concept Real time orbits are accurate to several cm, clocks are sub-ns Open data policy but registration is required But no service guarantee Using open standards (RTCM) Supports RT-PPP Register at: http://rts.igs.org IGS Real Time Service (RTS)

  4. International effort with many contributions: +25 Station operations, Data Centers, Analysis Centers, Combination Centers, Analysis Coordination, caster operation, … IGS Real Time Service

  5. IGS Real-Time Global Network 150+ stations 5

  6. RTS launched 1 April 2013 Note: IGS01/IGC01 (GPS-only) and IGS02 (GPS-only) streams now fully configured and running on 2 or more servers IGS03 (GPS+GLONASS) “experimental” stream RTCM3EPH streams (GPS, GLONASS, Galileo) Reference is ITRF2008 Stream access via BKG NTRIP Client (BNC) or RTKLIB Register for user access rts.igs.org Products: IGS Real-Time Products

  7. 10 Analysis Centres: IGS RT Analysis Centres

  8. IGS RTS Redundancy Concept

  9. IGS RTS Redundancy Concept

  10. Satellite orbit RMS (compared to IGS Rapid) IGS RTS Product Performance Average rms: 30 mm

  11. Satellite clock std.dev. (compared to IGS Rapid) IGS RTS Product Performance Average Sigma: 0.13 ns

  12. IGS RTS Product Performance IGS01

  13. IGS RTS Product Performance Note: results from IBGE Brazil using BNC with RBMC station data

  14. Innovative support for public benefit applications Enables real time precise point positioning (PPP) at global scales for scientific and hazard detection applications, weather and space weather forecast, multi constellation performance monitoring Rapidly detecting, locating, and characterizing hazardous events such as earthquakes and tsunamis Contributing to GGOS Theme 2 “Natural Hazards” IGS RTS Applications APF

  15. 80 user registrations by April 8, from 38 countries 173 user registrations by June 6, from 41 countries By Organization Type: Engineering Services/Consulting 53 Academic 45 GNSS Equipment/Software 39 Government (Geodetic/Mapping) 15 Government (Geological/Geophysics) 4 Telecommunications 5 Positioning Services 2 IGS RTS Users http://igs.org

  16. Summary Remarks RTS is now officially launched providing open access through a registration process rts.igs.org The RTS is designed to be reliable because of the built in redundancy RTS products are accurate as quality assurance indicators show The RTS is targeting public good applications including the GGOS natural hazards theme Demonstrated interest since launch is very encouraging

  17. 2012 2013 2014 2015 2016 2017 IGS Multi-GNSS Plan High quality multi-GNSS network and products High quality GPS/GLONASS network and products MGEX Transition Multi-GNSS Pilot Service • Build-up and share multi-GNSS know-how • Build-up network and provide access to multi-GNSS data • Develop prototype multi-GNSS products • Develop recommendations and standards • Engage with receiver manufacturers and system providers • RTS GPS PP • Merge legacy and multi-GNSS networks • Achieve interoperability of legacy and multi-GNSS products and services • RTS GPS+GLONASS • Incorporate BeiDou, Galileo, and QZSS into standard IGS processing • Issue combined and quality controlled multi-GNSS IGS orbit, clock and iono products • Regular multi-GNSS intersystem, interfrequency and intersignal bias estimation • Link GNSS system times with IGS system time • Embed new GNSSs into IGS/IAG reference frames • RTS for multi-GNSS http://igs.org
