Open challenges in TT&C: The control of mega-constellations and IoT for Earth Observation

#talk #session

The TT&C is a critical function that ensures the spacecraft system operates properly, by sending Telecommand, receiving Telemetry, and doing tracking for the orbit determination.

Although the TT&C engineering for LEO satellites is well consolidated, when it comes to the design of TT&C subsystems for low-latency and large networks there are several open research directions.

This seminar will provide an overview of the main challenges that are faced when designing the TT&C for such kind of networks, taking as main reference Mega-constellations and IoT for the Earth Observation.

The level of technical details will be provided in a style to help attendance to get familiar with the topic, thus making the seminar accessible also to engineers outside the specialty of TT&C.

Dr. Andrea Modenini Dr. Andrea Modenini of European Space Agency (ESA), at the European Space Research and Technological Centre (ESTEC)


Andrea Modenini received the Ph.D. degree from the University of Parma in January 2014. Since March 2015, he has been with the European Space Agency (ESA), currently working as a TT&C Communications Systems Engineer, supporting ESA Earth Observation and Scientific satellite missions, research and development of TT&C units, techniques, including those for unmanned aerial vehicles. He is also contributing to the education in the field of TT&C as a tutor of ESA trainees. Finally, he is involved in several standardization activities for satellite TT&C in the framework of ECSS, SFCG, and CCSDS. For the latter, he is the Chair of the Coding & Synchronization Working Group.
