Topic: Microwave and mm-Wave Backscatter for Ultra-Low Power Communications
Abstract: Originally seen as a niche communication technology for getting passive RFID tags to operate over a few meters of range, backscatter radio has become a key enabling technology of emerging IoT and low-powered/passive sensing. In this talk, we survey several key innovations in antennas, electronics, and signaling that allow backscatter communications to work up to kilometer-scale distances. As we will show, higher frequency works better for backscatter radio systems, which will lead to many unique sensing and communications applications in the near future.

European Space Agency
Topic: The future of Lunar Communications
Abstract: This decade will witness a proliferation of missions to the Moon, including orbiters, ascent and descent modules, surface vehicles, each potentially supporting crewed operations. Such missions have very diverse communications requirements in terms of data rate, availability, latency, and will be operated by ground segments spread over multiple space agencies and commercial operators. The Interagency Operations Advisory Group (IAOG) took the task of defining a communications architectural framework based on projected needs, with an emphasis on ensuring full interoperability among space agencies and commercial operators.
A dedicated working group including representatives from IOAG space agencies was formed and acted during 2018-2019, leading to an architecture expressed through a comprehensive report. There were several constraints, sometime mutually conflicting, to be adhered to: 1) the communications architecture had to originate within solutions formulated in the Consultative Committee for Space Data Systems (CCSDS), however with a mandatory down-selection, to limit the variety of solutions to be supported and increase inter-operability; 2) the architecture had to take into account the parallel development of the Lunar Gateway, in the process of defining its own standard, however with a wider scope encompassing the international landscape of missions to the Moon; 3) the recommendations from the Space Frequency Coordination Group (SFCG) about frequency bands to be used had to be adhered to, with the same down-selection principle adopted for CCSDS; 4) new technology had to be infused to boost performance and manage complexity, in terms of newly adopted radio frequency bands, use of optical communications and delay/disruption tolerant networking (DTN); 5) support to spacecraft/assets navigation and tracking had to be included.
The “new decade” has started already, and the space community is heading to our natural satellite, also as an interim step towards Mars exploration. The coherent communications framework identified by IOAG is an enabler of opportunities, like communicating with astronauts at very large data rate for remote medical support, or serving multi-assets located on the Moon south-pole, or ensuring continuous coverage to Lunar modules during critical phases by multi-agencies ground segments: materialising the above will require a high level of coordination among space agencies, but will definitely pay off in the long term path of human exploration.
Biography: Marco Lanucara graduated from “La Sapienza” university of Rome in 1994 in electrical engineering. In 2000 he joined the European Space Agency in the Operations Department, to follow the development of the ESA first deep space antenna built in New Norcia (Australia), which supported the Mars Express launch and Mars Orbit Insertion, as well as its still on-going science phase. Since 2010 he is the head of the Systems and Project support section, dealing with the design of satellite communications links for ESA near Earth and interplanetary missions. His main interest is about signal theory and its application to space communications and tracking. He represented ESA in the Lunar Communications Architecture working group of the Interagency Operations Advisory Group (IAOG) and will co-chair, together with NASA, the “Mars and beyond” communications architecture working group.
