Scenario of research Point of contact JAXA ORGANIZATION CHART Prospects on JAXA/NICT Participation Space-to-Space scenario (e.g.,LEO-GEO) Tomohiro ARAKI Aerospace Research and Development Directorate Satellite Applications Mission Directorate I Space-to-Earth scenario (e.g., Deep space-Earth) Tatsuya MUKAI JAXA Space Exploration Center Two optical comunication study groups in JAXA Institute of Space and Astronautical Science Internal secretariat Shinichi INAGAWA Space Tracking & Data Acquisition Department Collaboration NICT (Space Communication Systems Laboratory)
Space-to-Space scenario study group hopes to contribute. Our prospect is from 2016 and on. Wavelength: to be yet decided Modulation/Demodulation: compatible to BPSK homodyne and DD-DPSK Planned Schedule: research of key components 2012–2014 Development or System BBM in 2015- (TBD) Prospects on JAXA/NICT Participation Space-to-Space scenario (e.g.,LEO-GEO)
Space-to-Earth scenario study group a strong interest in Deep space or space science mission and hopes to contribute. Our prospect is from 2015 or 2016 according to their research status. Wavelength: 1.5μm band (TBD) Modulation/Demodulation, and so on: Under study This group has one of concern that the selection of technologies in Asia region like Japan would not be exactly same as those in other regions, because of diffrent weather conditions and some different operation required. Prospects on JAXA/NICT Participation Space-to-Earth scenario(e.g., Deep space-Earth)
Possible NICT contributions to CCSDS activities Followings can be possible inour activities including SOTA and VSOTA missions. • Laser beam propagation data at 1.5 μm • Atmospheric turbulence model • Coding for free-space laser communications • Real-time atmospheric monitoring and forecast • Handover, DTN
Regarding the traded-off between the projects originally proposed in OLSG (2 Green Books and 2 Blue Books) and alternative projects (2 Green Books and 3 Blue Books), we consider that it is better to proceed with the original projects in the phase of book development because it is easy to discuss for every scenario. • In the phase of application of Blue or Green Books, it is better to keep the form proposed in the alternative projects because it is convenient when selecting technologies in each Book depending on each layers. • Assuming future re-editing of the original projects into the form proposed in alternative projects, we consider proceeding with the original projects is favorable.
