Solar LMA - Langmuir Lab 2010

Solar power moves system away from infrastructure to quieter RF

environments, reduces noise and improves sensitivity

Next Generation LMA on a chip

2011•low power 1-2 watts, simple,

compact, very robust.

•LMA on a FPGA chip, no computer.

•store data on a compact flash.

•no communication in basic station.

•GPS, log amp, filters, pre amp as in other stations.

Page 38: The Lightning Mapping Array 12 years of evolution and growth

LMA station development•1996-98 designed initial system under NSF

MRI grant.

•1998 LMA-G1 initial operation in OK and NM using a desk-top computer with custom designed LMA board.

•2000 LMA-G2 design used a small single board computer. Used for the North Alabama system.

•2005 LMA-G4 developed the portable LMA under NSF SGER. First use: Augustine Volcano, 2006.

•2008 compact lower power solar powered design with solid-state hard drive.

•2011 LMA-G5 on a chip, small and low power.
