<p>We describe a network of sensors linked by sofmare and the internet to an autonomous satellite observation response capability. This sensor network is designed with aJlexible, modular, architecture to facilitate expansion in sensors, customization...
Onboard classifiers for science event detection on a remote sensing spacecraft
Found in: Proceedings of the 12th ACM SIGKDD international conference on Knowledge discovery and data mining (KDD '06)
By Ashley Davies, Ben Cichy, Dominic Mazzoni, Nghia Tang, Rebecca Castano, Ron Greeley, Steve Chien, Thomas Doggett
Issue Date:August 2006
pp. 845-851
Typically, data collected by a spacecraft is downlinked to Earth and preprocessed before any analysis is performed. We have developed classifiers that can be used onboard a spacecraft to identify high priority data for downlink to Earth, providing a method...
