Real Time Data (Overview)

The RTS is overseen by the IGS Real-time Working Group. The Real-time Analysis Center Coordinator (RTACC), currently the European Space Agency’s Space Operations Centre in Darmstadt, Germany (ESA/ESOC), has operational responsibility for the generation of the official combination products. These are generated at several combination servers and combine products from up to ten Real-time Analysis Centers. RTS is distributed through two primary Product Distribution Centers and a number of secondary centers that provide a highly available service.

Analysis Centers

The IGS combination products can only exist because of the contributions of the individual solution streams from the participating Analysis Centers. Below is a short description of the contributing solutions from the participating ACs.

Center Description
BKG GPS RT orbits and clocks using IGU orbits
GPS + GLONASS RT orbits and clocks using IGV orbits
CNES GPS RT orbits and clocks based on IGU orbits
GPS+GLONASS orbits and clocks
DLR GPS RT orbits and clocks based on IGU orbits
GPS+GLONASS orbits and clocks
ESA/ESOC GPS RT orbits and clocks using NRT batch orbits from ESOC s/w running every 2 hours
GPS RT orbits and clocks using IGU orbits
GFZ GPS RT orbits and clocks and IGU orbits
GMV GPS RT orbits and clocks based on NRT orbit solution
GPS+GLONASS orbits and clocks
Geo++ Not contributing at present. Working on RTCM SSR Standard.
NRCan GPS RT orbits and clocks using NRT batch orbits every hour
TUW Not contributing at present
WUHAN GPS RT clocks based on IGU orbits

The following agencies have additional functions in the RTS:

  • NRCan – RT Working Group Chair
  • ESOC – Real Time Analysis Center Coordinator
  • BKG – Data Flow Coordination
Combination Centers

The RTS Combination Centers are hosted by:

  • European Space Agency’s Space Operations Centre in Darmstadt, Germany (ESA/ESOC)
  • German Federal Agency for Cartography and Geodesy (BKG)
  • Natural Resources Canada (NRCan)
Product Distribution Centers

The IGS Central Bureau (IGSCB) and the German Federal Agency for Cartography and Geodesy (BKG) are the two primary Product Distribution Centers. Users may be also referred to an alternate product distribution centers upon confirmation of registration.
