"Peregrine: An Antarctic Aerial Drone Utilizing SDR and Raspberry Pi for Subglacial Exploration"

Researchers from the Stanford Radio Glaciology lab have developed a modified UAV called Peregrine, equipped with a miniaturized ice-penetrating radar system based on a software-defined radio (SDR) and a Raspberry Pi. The lightweight and cost-effective drone aims to provide valuable data on the health of Antarctic ice by gathering information about depth, fractures, fissures, and melt flow beneath the surface. The Peregrine drone, along with future larger designs, could be deployed from existing research stations to monitor the entire coastal region of Antarctica, offering a more efficient and affordable alternative to crewed airborne systems.
