Highly Efficient, High-Speed Technology for Satellite Communications
January 8, 2016 | University of TokyoEstimated reading time: 2 minutes
The research group of Professor Shinichi Nakasuka at the University of Tokyo Graduate School of Engineering and Professor Hirobumi Saito at the Institute of Space and Astronautical Science (ISAS), Japan Aerospace Exploration Agency (JAXA) has developed the most efficient 64APSK data transmission system yet for an Earth observation satellite. The system was installed in the Hodoyoshi 4 satellite, which has a mass of just 64 kg, produced by Professor Nakasuka’s group. Using this system, the research group transmitted data from Hodoyoshi 4 at a rate of 505 Mbps to the ISAS 3.8m antenna station at the JAXA Sagamihara Campus, where it was received and successfully decoded.
“This is the fastest communication speed achieved with a micro satellite and builds on our earlier achievement of a record 348 Mbps in February 2015,” explains Professor Saito. He continues, “In this demonstration, only the 125MHz radio frequency bandwidth was utilized from among the full bandwidth allocation. Using the full available bandwidth, it is technically possible to achieve 3,000 Mbps data transfer rates. With proposals to deploy hundreds of micro satellites to send back near real-time images or movies of the Earth, this type of high speed communications technology will become essential.”
