  • European Geosciences seeks abstracts for high-precision GNSS session

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

    One session in particular focuses on high-precision GNSS, and abstracts are being sought.

    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 welcome.

    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 welcome on all aspects of these issues. Deadline for receipt of abstracts is Jan. 11.

  • Abstracts Sought for EGU Session on High-Precision GNSS

    The General Assembly of the European Geosciences Union will feature a high-precision GNSS session, and is seeking paper submissions. The EGU General Assembly will be held in Vienna, Austria, April 12-17, 2015.

    The conference will bring together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary and space sciences. The EGU aims to provide a forum where scientists, especially early career researchers, can present their work and discuss their ideas with experts in all fields of geoscience.

    The session, “G1.3 – High-Precision GNSS Algorithms and Applications in Geosciences,” is an activity of IAG Sub-Commission 4.5 “High-Precision GNSS Algorithms and Applications.”

    Deadline for receipt of abstracts is January 7. To submit an abstract, visit the website.

    Session G1.3 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 systems are about to start providing the user signals, and both, GPS and GLONASS are currently undergoing a significant modernization, which adds more capacity, more signals, better accuracy and interoperability, etc. This, however, also results in new challenges in data processing. Moreover, the new developments in GNSS stimulate a broad range of new applications.

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