The IGS Infrastructure is the backbone and heart of all IGS products.
This session is a deep dive into the core infrastructure, data and digital systems, and the pivotal role of RINEX (Receiver Independent Exchange Format) as the community standard for GNSS data exchange.
Uncover the inner workings of the GNSS network, dissecting its complex infrastructure that encompasses ground stations and the interlinking systems orchestrating precise PNT services globally. Delve into the technological backbone that underpins these systems, discussing the challenges and innovations driving their evolution.
Discover how digital systems form the control centre of GNSS operations, facilitating data collection, processing, and dissemination.
Furthermore, the session will spotlight RINEX as the globally accepted standard for GNSS data exchange. Gain insights into the significance of RINEX in promoting synergies among researchers, scientists, and industry professionals. Explore its structure, its evolving adaptations and potential innovative formats within the GNSS ecosystem.

By providing long, precise position time series for a dense global network of GNSS stations, as well as accurate polar motion time series, the IGS makes a fundamental contribution to the construction of the International Terrestrial Reference Frame (ITRF). GNSS station position time series, often derived from precise IGS ephemerides, also find wide usage in the study of diverse geophysical processes. Yet, despite the tremendous progress achieved in the analysis of GNSS data over the last decades, the IGS geodetic products remain affected by random and systematic errors that limit their contribution to the ITRF and geophysical interpretation.
In this session, we seek contributions on any improvements to the analysis and modeling of GNSS data that could further augment the value of IGS products, including ephemerides and station position time series, but also global geodetic parameters (Earth rotation parameters, geocenter coordinates and terrestrial scale estimates). Topics may include, but are not limited to:
-
- GNSS satellite orbit modeling (attitude, solar radiation pressure, other non-conservative forces, etc.);
- characterization of GNSS satellite antennas (estimation / validation of phase center offsets, phase variations and group delays, impact on terrestrial scale);
- characterization and improvement of ground GNSS antennas (comparison / validation of phase center offsets and variations, in-situ calibrations, multipath mitigation or modeling, etc.);
- joint processing of legacy and new (BeiDou, QZSS, NavIC) navigation satellite systems;
- joint processing of observations from ground- and space-based receivers;
- joint processing of GNSS data with other space geodetic techniques;
- improvements and aliasing assessment of background solid Earth, ocean and pole tide models;
- use of non-linear a priori TRF components (e.g., ITRF2020 seasonal station motions);
- statistical modeling of GNSS station position time series.

The international, regional and national reference frames provide the spatial datum of millimetre-level precision for a large variety of applications in geosciences, surveying, cadastre and civil engineering. In recent years, mass-market applications have experienced a rapid development in automated mobility, precision farming, personal applications, etc. In order to exploit such a high precision for these applications, sophisticated methods are needed for postprocessing and real-time positioning services. Today, multi-GNSS observations of more than 100 satellites on different signal bands are available and need to be combined in a consistent way considering orbit and clock errors, atmospheric signal delays or signal biases. These quantities need to be estimated and provided for the users in standard formats. Real-time positioning services such as the IGS Real Time Service (IGS RTS) provide corrections which favour user positioning at a precision of up to a one or two decimetres by Precise Point Positioning (PPP). In order to improve the precision to the centimetre level at short convergence times, dense observation networks and full sets of correction data are needed.
The session 3 encourages for contributions on GNSS methods to give users and their applications (direct) access to the reference frame. Among others this includes the following key topics:
-
- GNSS real time infrastructure (e.g. station networks, data centres, data communication)
- High precision GNSS positioning services, applications and software
- Standardization of GNSS product formats
- GNSS correction products (e.g. orbits, clocks, atmospheric parameters, biases)
- Consistent processing of multi-GNSS observations for Positioning, Navigation and Timing (PNT) applications
- Realization of regional reference frames for regional applications

In this session, we explore the expanding role of the Global Navigation Satellite System (GNSS) in climate science, an area of significant interest for the IGS Ionosphere and Troposphere Committees. GNSS has transcended its traditional navigational uses, proving invaluable in climate monitoring and analysis. It offers unique insights into long-term climate patterns and atmospheric changes, especially in the ionosphere and troposphere. By measuring variables like water vapour, electron content, and temperature variations, GNSS data is instrumental in enhancing our understanding of these layers’ interactions with the climate system.
This session also highlights the use of GNSS in predicting and analysing extreme weather events, contributing to more accurate forecasting and effective disaster management strategies. Furthermore, we delve into the realm of space weather research, examining how GNSS contributes to our understanding of solar and cosmic influences on Earth’s climate. The session aims to showcase cutting-edge research and foster cross-disciplinary collaboration. It provides a platform for meteorologists, climatologists, GNSS experts, and other related professionals to share insights, develop partnerships, and contribute to a comprehensive understanding of our climate system, emphasizing the innovative application of GNSS in climate-related studies and space weather research.
