Tour de l'IGS

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.

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
