“…DOMINO project aims to demonstrate the feasibility of freespace optical communication by studying the link between SOTA (Small Optical TrAnsponder), [8], [9] on board SOCRATES microsatellite (launched on May 24, 2014), and the MeO station, [10], located at Caussols, France. The main challenges of the project are the implementation of a complete laser communication from space to ground and the characterization of the turbulent atmosphere during the optical data transfer [14]. The optical link between the SOCRATES micro-satellite and the Meo Optical Ground Station (OGS) has been successfully established for all of 4 scheduled passes on June 22, 23, 28 (10 Mbps at 1549 nm) and July 21 (10 Mbps at 976 nm).…”

In collaboration between CNES, NICT, Geoazur, the first successful lasercom link between the micro-satellite SOCRATES and a non-Japanese OGS has been established. This paper presents some results of telecom and scintillation first data analysis for 4 successful links in June & July 2015 between SOTA terminal and Meo optical ground station (OGS) at Caussols France. The telecom and scintillation data have been continuously recorded during the passes by using a detector developed at the laboratory. An irradiance of 190 nW/m² and 430 nW/m² has been detected for 1549 nm and 976 nm downlinks at 35° elevation. Spectrums of power fluctuation measured at OGS are analyzed at different elevation angles and at different diameters of telescope aperture to determine fluctuations caused by pointing error (due to satellite & OGS telescope vibrations) and caused by atmospheric turbulence. Telecom signal forms and bit error rates (BER) of 1549 nm and 976 nm downlink are also shown at different diameters of telescope aperture. BER is 'Error Free' with full-aperture 1.5m telescope, and almost in 'good channel' with 0.4 m sub-aperture of telescope.

“…The MeO telescope ( Fig 6) has been upgraded in order to be able to take part in laser telecommunications experiments. An uplink beacon has been added to the telescope, together with a receiver bench and a dedicated instrumentation used to monitor the link [3]. The telescope was already equipped with an Adaptive Optics (AO) bench called ODDISEE.…”

“…The telecom detection chain used for the OPALS experiment is a modification of the mono-pixel sensor initially designed for SOTA links [3]. It is made with an InGaAs avalanche photodiode, a low noise trans-impedance amplifier and two amplification channels for both telecom and scintillation detections.…”

INTRODUCTIONOptical transmissions between earth and space have been identified as key technologies for future high data rate transmissions between satellites and ground. CNES is investigating the use of optics both for High data rate direct to Earth transfer from observation satellites in LEO, and for future telecommunications applications using optics for the high capacity Gateway link. In order to assess the feasibility of these future systems, several studies have been initiated for investigating the propagation channel and its impact on the data transmissions. The aim is to define the more appropriate physical layer, in terms of choice of modulations, coding and interleaving, so that to obtain a robust data link. In order to design future optical transmission systems, field measurements are necessary to confront models with real conditions. The DOMINO project, which stands for "Demonstrator for Optical transMission at hIgh data rate iN Orbit)", aims at performing field measurements with international partners.

“…Furthermore, NICT has developed SOTA, the Small Optical TrAnsponder, which has been embarked on the SOCRATES satellite and is the main subject of this paper. SOCRATES has been launched on 24 th of May, 2014, and a number of experiments to NICT's optical ground station in Tokyo have been performed [8], as well as to international partners [9]. Besides that, the German Aerospace Center (DLR) has been developing experimental optical communication payloads within its OSIRIS project as well.…”
