GNU Radio is an increasingly popular framework for Software Defined
Radio components and Digital Signal Processing prototyping. As such our
goals are as follows:

* Bring together active French and European GNU Radio users, coming
  from a scientific, technical, amateur or hacker background 
* Foster interaction between GNU Radio users Share knowledge about GNU
  Radio development through tutorials, seminars and demos 
* Bridge the gap between technical/engineering and scientific/research 
  points of view on topics related to applied research with GNU Radio. 
  Such topics include: 
    Software Defined Radio, radio prototyping, 
    RF design, 
    RADAR design 
    Global Navgation Satellite Systems (GNSS) and space communications
    Signal processing in embedded systems,
    GNU Radio development environment,
    New platforms

GNU Radio users and developers are invited to present their experiments
and activities. The first day (22nd of June) will be devoted to oral
presentations, posters and demonstrations. The second day (23rd of
June) will be dedicated to tutorials and hands-on sessions.

Abstract :
The measurement of time has always been closely related to the
observation of the Earth. Today, the best optical atomic frequency
standards can reach inacurracies around 10?18 in terms of relative
frequency. Because time flow is affected by gravity, it means optical
clock comparisons could measure gravity potential differences with an
accuracy of 0.1 m2/s2, which is equivalent to 1-cm in height difference,
opening new fields of fundamental and applied research.
In this talk, we will introduce what is an optical atomic clock and
how remote clock comparisons could help us improve the knowledge of the
Earth’s gravity field. Then, we will present various applications that
could bring the exploitation of clock measurements in geodesy:
determination of the geopotential with high spatial resolution, vertical
reference system, and we will discuss the possible applications
associated to the geodynamic processes related to mass transfers.

The Midi-Pyrénées observatory organizes a national colloquium (conferences and poster exhibition) entitled “GNSS for science”, on February 4, 2020 at the Concorde Amphitheater, building U4, Paul Sabatier University, Toulouse.

Free but mandatory registration and poster submission before 2019/12/31 on https://gnssciences.sciencesconf.org

Call for papers: Authors of research on scientific applications of GNSS methods are invited to present them in the form of posters. To submit a poster, send a summary of approximately 500 words (1 A4 page) in French. Abstracts will be distributed during and after the colloquium.

Evening tribute to Richard Biancale: Monday, February 3 from 19 hours, Osete Room, Espace Duranti, 6 Rue Lieutenant-Colonel Pélissier, Toulouse. The Midi-Pyrénées Observatory, its parent institutions and the scientific networks of the French geodesy will pay tribute to Richard Biancale. Lecture by Georges Balmino (emeritus researcher at CNES).

This event is organized by the Midi-Pyrénées Observatory with the support of its parent institutions (CNRS, IRD, Paul Sabatier University, CNES, Météo-France), and by the COMET-PDS, the G2, the GRGS, the CNFGG and the AFT.
