Session
Technical Session IX: The Year In Retrospect
Abstract
Several previous satellites (Cosmos 1809 and Aureol-3) had detected anomalous extremely low frequency (ELF) magnetic field signals prior to and after large earthquakes around the early 90's. There were questions regarding signal levels, signal structure, frequency ranges, timing, and the ambient noise environment that made it difficult to specify larger science satellites to thoroughly test the theory that ELF might be a precursor signal to large earthquakes. An inexpensive nanosat (QuakeSat) was built, launched in June 2003, and flown to help determine the design parameters and values needed to build a research satellite for this mission.
