aviation
Dr. Jiyun Lee has made breakthrough contributions that guarantee the safety of satellite-based navigation systems for aviation against ionospheric disturbances. She developed new ionospheric threat modeling methods, novel ionospheric anomaly monitoring algorithms and mitigation techniques, and efficient system performance evaluation tools for integrity and availability assessment for Ground Based Augmentation Systems (GBAS), while achieving many scientific discoveries in the field of ionospheric research. She is a leading contributor in developing ionospheric anomaly threat models and assessing nominal ionospheric spatial decorrelation in mid-latitude and low latitude regions for GBAS operations.
Dr. Lee and her team pioneered a number of innovative navigation technologies that support safe and autonomous operation of Uncrewed Air Vehicles (UAVs) and Urban Air Mobility (UAM). Her team is the first to propose and develop a low-cost local-area GNSS augmentation architecture for UAVs and a network operations that emphasizes low cost and high integrity to allow UAVs (or UAM) to operate in close proximity to each other while minimizing collision risk. Her team’s recent contributions include sensor fault monitoring and integrity risk assessment techniques for multi-sensor integrated systems, including Kalman filter-based GNSS/INS systems, terrain referenced navigation systems LiDAR/INS, and RTK/INS systems.
Dr. Jiyun Lee is a KAIST Endowed Chair Professor in the department of Aerospace Engineering at the Korea Advanced Institute of Science and Technology (KAIST). She is an associate editor of ION’s journal, NAVIGATION, and serves on the ION’s Satellite Division Executive Committee. She has served ION as technical representative, and program or track chair multiple times. She holds an MS in Aerospace Engineering Sciences from the University of Colorado at Boulder, and an MS and PhD in Aeronautics and Astronautics from Stanford University.
