Andrew O'Brien's research centers on GNSS-Reflectometry (GNSS-R), a remote-sensing technique that uses reflected satellite navigation signals to observe the Earth's surface from space. Much of the work involves the CYGNSS satellite mission and applies these methods to detect floods, map surface water and wetlands, and estimate wind and wave conditions over inland waters. The publication record also includes items on unrelated topics, likely reflecting shared or ambiguous author names in the underlying data.
