Dear Colleagues,


The General Assembly of the European Geosciences Union will be held in Vienna, Austria, 23-28 April 2017.


We draw your attention in particular to session:

G1.4 - High-precision GNSS: methods, open problems and Geoscience applications



This session is an activity of IAG SC4.4. “Multi-constellation GNSS” and IAG-ICCT JSG 0.10 “High-rate GNSS”


Session G1.4 description:

In the past two decades high-precision GPS has been applied to support numerous applications in Geosciences. Currently, there are two fully operational Global Navigation Satellite Systems

(GNSS), and two more are in the implementation stage. The new Galileo and BDS systems already provide usable signals, and both, GPS and GLONASS, are currently undergoing a significant modernization, which adds more capacity, more signals, better accuracy and

interoperability, etc. Meanwhile, the huge technology development provided GNSS equipment (in some cases even at low-cost) able to collect measurements at much higher rates, up to 100 Hz, hence opening new possibilities. Therefore, on one side, the new developments

in GNSS stimulate a broad range of new applications for solid and fluid Earth investigations, both in post-processing and in real-time; on the other side, this results in new problems and challenges in data processing which boost GNSS research. Algorithmic

advancements are needed to address the opportunities and challenges in enhancing the accuracy, availability, interoperability and integrity of high-precision GNSS applications. 

This session is a forum to discuss new developments in high-precision GNSS algorithms and applications in Geosciences; in this respect, contributions from other branches in Geosciences (geodynamics, seismology, tsunamis, ionosphere, troposphere, etc.) are very


We encourage, but not limit, submissions related to:

- Modeling and strategies in high-precision GNSS,

- Multi-GNSS benefit for Geosciences,

- Multi-GNSS processing and product standards,

- Inter-system and inter-frequency biases and calibrations,

- New or improved GNSS products for high-precision applications (orbits, clocks, UPDs, etc.),

- Precise Point Positioning (PPP, PPP-RTK),

- High-rate GNSS,

- GNSS and other sensors (accelerometers, INS, ecc.) integration for high-rate applications,

- Ambiguity resolution and validation,

- CORS services for Geosciences (GBAS, Network-RTK, etc.),

- Precise Positioning of EOS platforms,

- Precise Positioning for natural hazards prevention,

- Monitoring crustal deformation and the seismic cycle of active faults,

- GNSS and early-warning systems,

- GNSS reflectometry,

- High-precision applications for Geosciences,

- and more.


Papers are welcomed on all aspects of these issues.


Deadline for receipt of abstracts is 11 January 2017:



Please consider submitting a paper for this session or contact us directly if you have any questions.
