DESCRIPTION:Prof. Alessandro Golkar\nThe FSSCAT mission is expected to be 
 launched onboard of the Vega SSMS Maiden Flight in mid 2019. In addition t
 o its remote sensing objectives\, the mission will demonstrate for the fir
 st time worldwide a reliable optical intersatellite link (O-ISL) between t
 wo 6U CubeSats flying in Low Earth Orbit (LEO). We have developed a techno
 logy demonstration with a full duplex O-ISL terminal of 1.5U in size (15cm
  x 10cm x 10cm)\, 85mm optical aperture\, suitable for LEO to LEO operatio
 ns on coarse pointing CubeSats (pointing accuracy < 0.5 deg). The terminal
  adopts a novel adaptive variable divergence laser mechanism with a hybrid
  payload/platform seek-and-track pointing algorithm\, and an amplitude mod
 ulated signal to ensure reliable optical communications at 1 Gbps at a nom
 inal intersatellite distance of up to 2\,000 km in LEO. In addition of est
 ablishing an intersatellite link\, the terminal provides the ability for s
 imultaneous imaging through the optical aperture and the improvement of th
 e attitude determination capability of the hosting satellite through the m
 ixing of optical information in the overall platform attitude feedback con
 trol loop. This presentation will describe the O-ISL systems architecture 
 and the concept of operations of the optical intersatellite technology dem
 onstration. The remote sensing objectives of FSSCAT\, implemented by the t
 eam at Universitat Politecnica de Catalunya led by Prof. Adriano Camps wil
 l be as well overviewed. The payloads carried onboard FSSCAT include a Fle
 xible Microwave Payload-2 (FMPL-2)\, a GNSS-Reflectometer\, an L-band radi
 ometer with interference detection/mitigation\, and a hyperspectral imagin
 g instrument. The science objectives of the mission include the measuremen
 t of soil moisture\, ice extent and thickness\, as well as the detection o
 f melting ponds over ice.\n\nAlessandro Golkar is Associate Professor at S
 koltech in Moscow\, Russia\, and Visiting Professor at the Universitat Pol
 itecnica de Catalunya in Barcelona\, Spain. He is currently serving as Vic
 e President Concurrent Engineering in the Airbus Corporate Technology Offi
 ce (CTO) organization in Toulouse\, France. Prof. Golkar is the Principal 
 Investigator of the Optical Intersatellite Link (O-ISL) experiment of the 
 FSSCAT mission\, funded by the European Space Agency\, Overall Winner of t
 he Copernicus Masters 2017 and 2017 ESA Sentinel Small Satellite Challenge
 . Prof. Golkar holds a Ph.D. degree in Aeronautics and Astronautics from t
 he Massachusetts Institute of Technology (MIT) and Master’s and Bachelor
 ’s degree in Astronautics and Aerospace Engineering from the Università
  di Roma “La Sapienza”.\n\n
