The Automatic Geophysical Observatories (AGO) are a network of remote stations used for collecting geophysical data in areas of Antarctica where regular maintenance is not possible. The AGOs consists of a suite of nearly identical instruments (optical and radio wave auroral imagers, magnetometers, and narrow and wide band radio receivers) placed at six specifically-sited locations on the polar plateau. The VLF Group operates  ELF / VLF Radio Receivers at the AGO sites as well as at South Pole station. For an introduction to the AGO program and the instrumentation visit the AGO page at the University of Maryland Upper Atmospheric Physics Group.
