Opening Session
Overview
Unified Analysis Workshops are co-organized by the International Association of Geodesy’s(IAG’s) Global Geodetic Observing System (GGOS) and International Earth Rotation andReference Systems Service (IERS). This is the 6th in a series of workshops that are held every
two to three years for the purpose of discussing issues that are common to all the space-geodetic
measurement techniques. Attendance at the Workshops are by invitation only with each IAG
Service nominating 5-6 experts to attend and participate in the discussion. ITRF2020 was
released in 2021 year and the focus of this year’s Workshop is ITRF2020. The Workshop is heldin conjunction with the Commission 1 Symposium, REFAG2022 which also focuses on
Reference Frames. At this year’s Workshop the discussion is focused on:

Unified Analysis Workshop
Systematic Errors and Biases in DORIS
Overview
The goal of the session is to present the experience gained during the DORIS ITRF 2020 reprocessing and the evaluation of the preliminary version of new ITRF (ITRF2020). Unlike SLR,
where precise geodetic solutions are based on spherical satellites observations, DORIS analysts
must deal with the specific shape and orientation of each satellite of the system, with risk of
introducing satellite-specific bias. New developments in the DORIS system and their impact on
the quality of DORIS products will also be presented. The impact of the South Atlantic anomaly
and its mitigation strategy is discussed as an important source of systematic errors in DORIS.

Systematic Errors and Biases in GNSS
Overview
A key focus of this session is the contribution of the International GNSS Service (IGS) to thelatest version of the International Terrestrial Reference Frame (ITRF2020). For the first time,
IGS included Galileo observations in addition to GPS and GLONASS observations in theprocessing of its contribution to the ITRF2020, known as Repro3. The calibrated antenna
measurements of the Galileo allowed for the first time for the terrestrial scale of the GNSS
solutions to be independent of the ITRF. Scale [rate] differences were observed between GNSS
solutions and the other geodetic techniques, which will be discussed in this session. Systematic
errors identified in the IGS Repro3 will be explored, such as those impacting the orbit modellingof the GNSS satellites. Other impacts from inclusion of Galileo in the GNSS solutions such as
those on the estimated coordinates will also be discussed. ITRF2020 included for the first time
seasonal signals; the potential impact of the seasonal signals on the GNSS solutions will be
explored.

Gravity Models for POD
Overview
The goal of the session is to examine the available state-of-the-art sources of information/models
for the description of static and time-varying gravitational forces in the process of PrecisionOrbit Determination (POD). The emphasis is on information/models available for analysis ofrecent/current data which implies a need for “forecasting” into the near future on the basis of past
years’ observations. The main focus will be on the very low degree components of thegravitational field due to their stronger influence on all orbits. Investigations on the definition of
the origin of the ITRF and its “variations” due to geophysical phenomena as well as possible GM
estimates from a multitude of SLR targets will be also presented and discussed.

Reference Systems and Frames
Overview
The terrestrial reference frame (TRF) is the foundation for virtually all space-based, airborne andground-based Earth observations. Through its tie to the celestial reference frame (CRF) by timedependent Earth orientation parameters, it is also fundamentally important for interplanetary
spacecraft tracking and navigation. The TRF determined by geodetic measurements is theindispensable foundation for all geo-referenced data used by science and society. It plays a keyrole in modeling and estimating the motion of the Earth in space, in measuring change anddeformation of all components of the Earth system, and in providing the ability to connect
measurements made at the same place at different times, a critical requirement for understanding
global, regional and local change. Providing an accurate, stable, homogeneous, and maintainable
terrestrial reference frame to support numerous scientific and societal applications is one of theessential goals of the International Association of Geodesy’s (IAG’s) Global Geodetic Observing
System (GGOS). This session is a forum for discussing the ways and means of improving theTRF, including understanding the inconsistencies of the current TRFs and the possibility ofjointly determining them with the CRF.

Reference Systems and Frames in Physical Geodesy
Overview
In 2015, the International Association of Geodesy (IAG) released two resolutions for the
implementation of two main components of a modern physical reference system. The first resolution
is devoted to the definition and realisation of a global unified height system. The realisation of the
global height system, conventionally called the International Height Reference Frame (IHRF), isbased on the determination of the gravity potential (and its variations with time) at station positions
defined in the International Terrestrial Reference Frame (ITRF). The second resolution concentrates
on the establishment of the International Terrestrial Gravity Reference Frame (ITGRF).
Measurements with absolute gravimeters, the traceability of which is ensured by inter-comparisonsand monitoring at reference stations, provide the basis of the frame. The status of implementation ofboth frames will be discussed and revised in this session. Furthermore, for the precise gravity
potential determination, a high-resolution gravity field modelling is needed. From this perspective,
this session presents also advances in the calculation of the high-resolution global gravity model
EGM2020 (Earth Gravitational Model 2020) and the comparison/calibration of analysis approaches
for the computation of the potential using gravity data of high-resolution. The session will close withsome insights into novel technologies for the measurement of the gravity field.

GGOS
(DOIs for Geodetic Data Sets & UN Global Geodetic Reference Frame)
Overview
This session will explore two topics identified by the GGOS Executive Committee as important
issues relevant to the analysis community: recent progress toward Digital Object Identifiers(DOIs) for geodetic data sets, as well as work of the United Nations Committee of Experts on
Global Geospatial Information Management (UN-GGIM) Subcommittee on Geodesy on
advocacy of the Global Geodetic Reference Frame, and progress toward establishing a UN
Global Geodetic Center of Excellence (GGCE) in Bonn, Germany. The session will focus on
introducing the participants to the current status of each topic, with extended time for discussion
and feedback. Discussion will be facilitated by the session co-chairs. Participants are encouraged
to ask questions and share their own experiences implementing DOIs, as well as to identify what
aspects of geodetic analysis should be considered of highest priority to the UN GGIM and future
GGCE.
