DLT and Timing
New York Stock Exchange
When it comes to financial transactions, time synchronization accuracy of all connected elements in a trading system is a critical, yet difficult, challenge. Distributed ledger technology (DLT) is transforming trade and trade financing creating disruption in spaces typically occupied by traditional information repository methods and ledgers. The use of DLT brings timing considerations of its own.
Financial industry timing regulations are stringent, mandating that time synchronization be accurate to 100 microseconds. With the goal of eliminating fraudulent security trades, regulations specifically call for:
Inaccurate time in an organization’s network, as well as the impact of this error on financial applications, may result in legal action.
DLT networks and their underlying infrastructure are held to the same time synchronization accuracy requirements demanded of financial institutions. This makes precision timing a critical enabler creating a trusted environment for real-time DLT transactions. ATIS’ Time and Money 2020 sheds light on the critical role of timing and synchronization in enabling secure transactions within a DLT environment. Join us to learn about timing’s role in advancing the DLT revolution.
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. =>informations

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
