TAFA 2019: 2nd International Symposium on Time And Frequency Applications

November 25th-29th, 2019, Wuhan (China).
The most precise measurement of time is presently realized by atomic clocks. The running rate of a standard atomic clock (or recently developed optical atomic clock) is controlled by the frequency of electromagnetic radiation that is determined by the difference between two hyperfine energy levels of the atom. Time and frequency play a key role in modern science and technology, and have a broad range of applications. The purpose of this symposium is to attract the national and international scholars to discuss the scientific problems related to the measurement of time and frequency and various potential applications of atomic clocks focusing on, but not limited to, the following topics: (1) tests of general relativity and, in particular, gravitational red shift with ultra-higher precision; (2) tests and comparisons of the running rates of atomic clocks in different moving systems on the ground and in space; (3) tests of the Lorentz and position invariance of special and general relativity; (4) tests of the time-variability of the fine structure constant and the other fundamental constants of elementary particle physics and quantum field theory; (5) relativistic geodesy and geoscience; (6) time and frequency transfer via various techniques (coaxial and/or optical fiber lines, two-way satellite time/frequency transfer, etc.); (7) gravity field modeling based on atomic clocks and ultra-high precise time-frequency signal transmission.

Journées scientifiques 2020 d'URSI-France « Réseaux du futur : 5G et au-delà » – Appel à communications

11-13 mars 2020, Institut Polytechnique de Paris (Telecom Paris) (Palaiseau, France).
Sous l'égide de l'Académie des Sciences.
En cette année de lancement de la Cinquième Génération de réseau radio-mobiles (5G), URSI-France a décidé de dédier ces journées aux réseaux du futur, appelés à transformer la société en profondeur au travers d'usages très innovants. Avec la 5G, les réseaux sans fil auront pour la première fois été conçus dès le départ dans le but de rendre possible à la fois les communications personnes-personnes, personnes-machines et machines-machines, donnant accès à une multitude de services reposant sur les données. Les développements technologiques propres à la 5G, la montée en fréquence, les évolutions prévisibles qui nécessiteront de déborder du cadre de la 5G pour aller vers la génération suivante, continueront à stimuler des efforts importants et de nouveaux axes de recherche, impliquant le monde académique et l'industrie. Cependant, si chaque nouvelle génération de réseaux mobiles se traduit par une complexification et un enrichissement des services proposés, elle induit aussi des craintes liées à la multiplication des sources de rayonnement électromagnétique, aux expositions associées et à la consommation énergétique . Il importe donc, sur l'ensemble de ces aspects, d'avoir une vision objective, propre à la démarche scientifique.
Dans ce contexte, les journées scientifiques 2020 d'URSI-France s'articuleront autour de sessions orales et posters. La plupart des sessions seront introduites par des conférenciers invités, présentant l'état de la technique et/ou des développements récents, suivies par des communications ayant fait l'objet d'une sélection par le Comité scientifique. Les supports seront en Anglais, les présentations orales pouvant être en anglais ou en français.
Principaux thèmes : Conception et mesures d’antennes ; Propagation et couche physique ; Nouvelles approches pour la conception, le dimensionnement, l’optimisation et la Gestion des réseaux ; Photonique ; Environnement électromagnétique, caractérisation des exposition et efficacité énergétique.
Date limite de soumission des résumés : 15 décembre 2019.

APPELS D’OFFRES

ESA Open Invitation to tender "Erbium-doped radiation-hard frequency comb - EXPRO+"

The primary objective of the proposed activity is to evaluate the performance of a fiber laser based Optical Frequency Comb (OFC) system, under well-defined ionizing radiation conditions. The target OFC performance shall assume the performance requirements of a defined future application of ESA. This OFC performance (specification) be established at the start of the project and will be the reference value for the final system. The final OFC performance, following well-defined radiation exposure parameters, shall meet the same performance of the un-radiated system. In order to meet the OFC performance after radiation, a specially developed radiation-hard doped fiber shall be developed as an integral element of the project.
Submission deadline: 04/11/2019.

ESA Open Invitation to tender "GNSS Science with commercial aircraft re-issue - EXPRO+"

Advanced GNSS-based processing techniques (e.g. exploiting simultaneously direct and reflected signals) applied to commercial aircraft can provide very useful scientific data with higher spatial and temporal resolution than current spaceborne instruments. The objectives of the activity are to: (a) evaluate benefits of the crowdsourcing strategy based on commercial aircraft in terms of coverage, revisiting time and enabled science applications; and (b) determine capabilities of the state of art of passive remote sensing techniques based on GNSS (multifrequency multiconstellation) and (c) define the instrument and the exploitation infrastructure. The result of the activity will provide: (a) the confirmation of technical feasibility of embarking GNSSbased remote sensing instruments in commercial aircraft, in order to complement Earth Observation satellite services; (b) the definition of requirements of airborne GNSSR instruments for the identified scientific applications; (c) the requirements and accommodation constraints from aircraft manufacturers and carriers; and (d) the identification of significant use cases, the preliminary design of the related airborne GNSSRinstruments and the definition of a representative endtoend concept demonstration.
Submission deadline: 11/11/2019.

ESA Open Invitation to tender "Resilient, trustworthy, ubiquitous time transfer Reissue - EXPRO+"

This REISSUED EXPRO+ procurement is part of the NAVISP Programme, under Elelment 1, Work Plan 2018.Secure and reliable time transfer is a key enabler for the next generation of wireless communications, positioning and navigation services worldwide. A number of different applications such as 5G mobile broadband, power grids, terrestrial positioning services and financial operations will require accurate, secure and reliable time information to be able to work consistently and efficiently. The time information will need to be transferred not only securely, but also in a seamless and ubiquitous manner. The most accurate and ubiquitous time transfer is currently realised through GNSS, and allows absolute time dissemination, however, with GNSS suffers from a number of limitations such as those related to intentional and non-intentional interference and possible signal blockage in difficult environments. Terrestrial methods such as Precise Time Protocol (PTP) are not absolute and less accurate but not affected by limitations of GNSS. Hence, the objective of the proposed activity is to develop innovative effective methods of time dissemination, time transfer and synchronisation, combining strengths of GNSS and terrestrial technologies. In order to enable an overall seamless provision of secure, ubiquitous and reliable time information, solutions to complement the current GNSS time transfer techniques with the emerging fixed and mobile services (e.g. 5G enhanced mobile broadband including new frequency bands, device-to-device and vehicle-to-vehicle/any, autonomous vehicles, terrestrial positioning methods, ...) will be assessed.
Submission deadline: 22/11/2019.

Joint HU-Berlin/FBH laboratory (Berlin, Germany).
The focus of the Joint Lab Integrated Quantum Sensors (IQS) is to develop the next generation of chip-scale quantum sensors for real world applications. These sensors use high-precision spectroscopy techniques applied to atomic or molecular ensembles either at room temperature or near absolute zero using laser cooling and advanced cooling mechanisms. Here, the intrinsic properties of quantum mechanical states and their precise manipulation with laser light are exploited in order to realize instruments for highly accurate measurements of physical quantities, such as frequency, time, inertial forces as well as electrical and magnetic fields.
R&D is carried out in close cooperation and is strategically synchronized with activities of the Joint Lab Quantum Photonic Components (QPC) at FBH, which in particular develops micro-integrated laser modules. Together, the Joint Labs IQS and QPC cover the full technology chain from components to systems.
