Workshop : « Atom Interferometry & Space Geodesy »

This will be held at CNES in Paris (2 place Maurice Quentin 75001 Paris) on September 28th and 29th 2016. The contributions will cover all aspects of this topic, from the design of the atomic sensors to the needs of end users in the fields of hydrology, glaciology, oceanography and geophysics. Furthermore, presentations of space agencies (CNES, ESA and NASA Goddard) will allow understanding the status of various international projects.

During the last decade, the rise of cold atom technologies allowed the emergence of new inertial sensors and the progressive industrialization of these devices. In particular, atomic accelerometers have been developed by CNES in the frame of technical R&D activities and scientific program. These new instruments have a high potential of applications in the field of space geodesy. This year, a new mission study has been initiated by CNES in order to determine the potential contribution of cold atom technologies to space geodesy and to the end users of the geodetic data. This workshop will be dedicated to the technical and scientific aspects of this topic. The contributions will address the main challenges, from the design of the atomic sensors to the needs of end users in the fields of hydrology, glaciology, oceanography and geophysics. Furthermore, presentations of space agencies (NASA, ESA and CNES) will detail the status of various space projects in order to identify future collaborations.
