We are pleased to announce that the second Symposium of the
International Association of Geodesy (IAG) Commission 4 "Positioning
and Applications" will be held during the week of September 7-11, 2020
in the Lecture Room of Building H, Telegrafenberg in Potsdam, Germany.
All interested individuals are invited to attend the meeting.

The 2nd IAG Commission 4 Symposium brings together scientists,
researchers and professionals dealing with the broad area of positioning
and applications. For this purpose, it will facilitate the discussion of
research that leverages current and emerging positioning techniques and
technologies aiming at delivering both practical and theoretical
solutions for engineering and mapping applications, GNSS-based
technologies, sensors fusion, and atmospheric remote sensing, modelling,
and applications, based on geodetic techniques. Recognizing the central
role of Global Navigation Satellite Systems (GNSS) in providing high
accuracy positioning information today and in the future, the 2nd IAG
Commission 4 Symposium will focus on ongoing research for improving
models and methods that enhance and assure the performance of GNSS-based
positioning solutions for a wide range of geodetic applications. The 2nd
IAG Commission 4 Symposium will be devoted to the discussion of theory,
strategies and tools for modelling and/or mitigating the effects of
interference, signal loss and atmospheric effects as they apply to
precise GNSS and other space geodetic techniques. They will address the
technical and institutional issues necessary for developing backups for
GNSS, integrated positioning solutions, automated processing capabilities
and quality control measures.

Besides positioning, another focus of the 2nd IAG Commission 4 Symposium
will be on remote sensing and modelling of the lower and upper atmosphere.
The Space Geodesy and Ionosphere (SGI) Workshop in 2020 is embedded in
this event.

This symposium will be carried out in close cooperation with the
International GNSS Service (IGS),
the IAG Global Geodetic Observing System (GGOS) Focus Area
ìGeodetic Space Weather Researchî,
as well as via linkages with relevant entities within scientific and
professional sister organizations.
The Symposium will be co-sponsored by the
International Association of Geomagnetism and Aeronomyís (IAGA),
Division II ìAeronomic Phenomenaî Working Group IIC ìMeteorological
Effects on the Ionosphereî.
Further partners are the Institute of Navigation (ION),
the Technische Universitat Berlin and the GFZ Potsdam.
