Tour de l'IGS

Technical Mini-Workshop Series | Presentations

The Tour de l’IGS is a series of virtual workshops on relevant topics to the IGS membership, stakeholders and GNSS community in general. These events will be hosted several times a year and will cover a wide range of topics including space-borne and ground-based instrumentation, technology development, scientific and societal applications, etc. To view event information, visit the Tour de l’IGS page.

 

Because we strive to improve our events and workshops, we have prepared a 5-minute post-workshop anonymous survey here: IGS Post-Workshop Survey. We would greatly appreciate any feedback and/or suggestions you might have!

4th Stop: BDS Constellation Spotlight 

27 September 2022

The 4th stop focuses on the latest progress of the BDS constellation. BDS is actively promoting international cooperation in an all-around way. In the 4th Tour de l’IGS, GNSS users could know the special services provided by BDS, including high-precision PPP-B2b service and Short Message Communication. This 4th stop will provide information on BDS featured services, BDS data usage, and the performance of BDS data processing.

3rd Stop: GNSS processing based on IGS products Presentations

17 February 2022

The third stop will provide GNSS users (even without a geodetic background) an overview on the value by applying IGS products for their activities. It focuses on GNSS processing based on IGS products focusing on geometric applications, e.g., coordinate estimation. You will be provided with information on

  • how to process and get ITRF coordinates for regional or local applications
  • which aspects of GNSS data analysis are relevant in this context
  • value of geodesy to other scientific/user applications
