The localization and identification of antarctic meteorites is a task of great scientific interest and with implications to planetary exploration. Autonomous search for antarctic meteorites presents a profound technical challenge.

In January 1998, we validated a 500 MHz GPR sensor as part of as field robotic technology demonstration at Patriot Hills, Antarctica.
