• Introduction to the IGS Real-Time Service (RTS)

• Redundancy in the production chain

• Accuracy of the products

• Interest since the launch

• Summary

Outline


• 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

IGS Real-Time Global Network

150+ stations


• RTS launched 1 April 2013Note:

– 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

• 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”

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
