PPP Workshop Ottawa Canada June 12-14 20132
• Introduction to the IGS Real-Time Service (RTS)
• Redundancy in the production chain
• Accuracy of the products
• Interest since the launch
• Summary
Outline
PPP Workshop Ottawa Canada June 12-14 20133
• 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

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
