Abstract :
[en] The extensive range of sensors, devices, and instrumentation on onboard space systems generates a substantial volume of data intended for transmission to the ground. However, the downlink data rate is inherently constrained by transmitting power and ground station access. Edge computing aims to reduce the latency and bandwidth within a downlink by processing the data as close as possible to where it has been generated, by placing the processing hardware close to the data source. In this paper, we apply edge computing to a payload for thermal anomaly detection, developed at the University of Luxembourg. The payload encompasses a series of Forward-Looking Infrared (FLIR) high-resolution Long-Wavelength Infrared (LWIR) micro-thermal cameras as an edge-sensing component to generate the thermal images. A Field-Programmable Gate Array (FPGA) acts as an edge-computing system for processing thermal images and heat distribution profiles, using a Support Vector Machine (SVM) algorithm to detect anomalies.
