Presented to: Dr. Dorota A. Grejner-Brzezinska
Citation: For her sustained contributions to advancements in the art and science of navigation, for her excellence as an academic teacher, and excellence in her service to The Institute of Navigation.
Dr. Dorota A. Grejner-Brzezinska has been involved in the art and science of navigation since the early 1990s. Her primary contributions include pioneering work on GPS orbit estimation and semi-diurnal Earth rotation parameter estimation using GPS. She developed a new, accurate, and extremely computationally efficient technique based on triple carrier phase differences. Additionally, she significantly contributed to the development of algorithms and methods for high-accuracy integration of GPS and inertial systems, leading to prototyping the algorithms and hardware of the AIMS system, developed at Ohio State University (OSU) in the mid-1990s. AIMS was the first high-accuracy directly georeferenced all-digital airborne mapping system based on a high-resolution digital camera and tightly integrated GPS/IMU. Since then, Dr. Brzezinska has contributed to the advancements of the state-of-the-art in multisensor integration methods and algorithms.
While at OSU, Dr. Brzezinska has been a principal investigator of numerous federally sponsored projects, leading significant research that resulted in new algorithms and software for kinematic network-based GPS for the National Geodetic Survey (NGS), followed by the development of rapid-static algorithms that formed the basis for the on-line OPUS-RS service supported by NGS. Later, she and her SPIN Lab team performed innovative research for the National Geospatial-Intelligence Agency (NGA) that resulted in novel algorithms for personal navigation in GPS-challenged environments and indoors, based on artificial intelligence methods. In recent years, she and her research team made significant contributions to image-based and terrain-based navigation, with their current research focusing on collaborative navigation.
As an academic, Professor Brzezinska provides continued and significant contributions to educating navigation and geodetic scie nce experts. In the past 11 years, since she became a faculty member at OSU, she graduated numerous PhD and MS students, was an academic adviser to a number of post-doctoral researchers, and has hosted many visiting graduate students and faculty from all over the world. She is frequently invited as a panelist and keynote speaker at national and international conferences, and teaches navigation-related workshops for the U.S. government and numerous universities around the world. She serves as technical expert for the National Academies Transportation Research Board. Dr. Brzezinska has published over 200 technical papers and five book chapters. She is the recipient of the 2005 ION Thurlow Award, the 2005 U.S. Geospatial Intelligence Foundation Academic Research Award and is the recipient of numerous research awards from OSU and best paper awards from the ION. She is a Fellow of the International Association of Geodesy.
