Her research is primarily in the fields of Global Positioning System/Global Navigation Satellite Systems (GPS/GNSS), multi-sensor integrated systems for assured navigation and autonomous vehicle navigation. Brzezinska’s most significant contributions include a novel approach to GPS orbit determination, which provided high-precision orbits and demonstrated for the first time the unique capability of diurnal and semi-diurnal Earth rotation parameters estimation using GPS signals. This pioneering work led to the advanced development of a NASA-sponsored new approach to kinematic/reduced dynamic precise orbit determination for Low Earth Orbiters. Brzezinska led an Ohio State team in the groundbreaking project Airborne Integrated Mapping System, which delivered first-in-the-world fully digital directly georeferenced high-accuracy airborne mapping system prototype based on tight integration of GPS and inertial navigation system.
One colleague stated, “Professor Brzezinska has had a vital and lasting impact on satellite navigation for more than 20 years. She has established an impressive research group at The Ohio State University that is recognized around the world for their work on geodesy, surveying and precise positioning using GNSS.”
She is the first woman from the university to be named to the National Academy of Engineering and is a Fellow of the Institute of Navigation (ION), the International Association of Geodesy and The Royal Institute of Navigation.
