Development of a New Portable Lightning Location System

open access: yesIEICE Transactions on Communications, 2012
Using a single-site lightning location technique, a new portable lightning location system is developed. We incorporate an attitude detection technique using inertial sensors to detect an accurate electromagnetic field vector of sferics by palm-sized electromagnetic sensors which can have arbitrary attitude.
