Signal Processing Applications


Dramatic increases in sensor resolution in remote-sensing space payloads are causing a processing bottleneck, as downlink bandwidth is not keeping pace. Operators require onboard processing so that satellites send processed information, not just raw data. It is a growing challenge for the roughly 100 remote sensing satellites launched each year, each carrying as many as eight payload instruments. Flash-based field-programmable gate array (FPGA) technology is now being applied to the problem, combining high-speed signal processing with special built-in radiation mitigation techniques to keep systems operational in harsh radiation environments.[Continue reading →]
