Abstract:

The concept of affordable access to space is a hot topic in the space industry, where reducing spacecraft mass/volume is a key element to meet a design-to-cost philosophy. By contrast, the satellite-based Earth Observation market is more focused on boosting the performance of sensing instruments, which in general drives the need to increase onboard transmitter RF power to deliver large information throughput in a relatively short time on the Space-to-Earth link. These two concepts are in contrast from an electromagnetic standpoint since it often becomes complex to make powerful RF sources and sensitive receivers coexist in little space. Technically, the RF "autocompatibility condition" is achieved whenever a radiating source does not cause hazardous effects on co-located victims, which means, in practical words, that the victim shall not exhibit permanent damage nor degraded performance when exposed to interference.

The presentation is focused on the use of dedicated and simple workflows within CST Studio Suite environment to handle radio-frequency auto-compatibility studies and to implement feasible mitigation action plans so as to address the impact at the system level. The same workflows are also relevant to evaluate how different antenna placement options contribute to assessing the overall pattern coverage around the spacecraft to provide flawless telemetry retrieval and telecommanding capabilities on/from the ground. On-going analyses in CST on phase center offset & variation (PCO/PCV) estimation for GNSS antennas are also presented by comparing free-space performance with spacecraft body-mounted configuration.
 

About the Speaker:

Andrea Giannini received his MSc Cum Laude in Electronic Engineering and his Ph.D. in electronics and computer science from the University of Pavia, Italy, focusing on parabolic antenna design for space applications and electromagnetic theory applied to radio-propagation studies.
Andrea spent three years at the European Space Agency as a Research Fellow to work on new generation ESA Deep Space Antennas arraying architectures for future Enhanced Mission Support at large data rates. After some years in the space industry, consolidating his ground operations background, Andrea took a massive leap toward the stars to work on satellite telecommunication systems. He currently works at D-Orbit as a Senior Telecommunication Engineer. He is the Telecommunication Lead Engineer for the NOX mission, developed under the framework of Italy’s Space National Recovery and Resilience Plan (PNRR), which will be an Earth observation constellation that will monitor critical infrastructure, air quality, and meteorological conditions using radar imaging techniques.
