About

Young-Jun Choi is a leading figure in space situational awareness and satellite observation, best known for founding and directing the OWL-Net project—a global network of robotic telescopes designed to track and characterize objects in Earth orbit. His most cited work, the 2018 paper "OWL-Net: A global network of robotic telescopes for satellite observation" (31 citations), details the system’s architecture and its critical role in monitoring space debris and active satellites. Choi’s contributions have significantly advanced optical surveillance capabilities, enabling precise orbit determination and supporting collision avoidance for space assets. His research bridges astronomy and aerospace engineering, with impact extending to national security and sustainable space operations. Beyond OWL-Net, he has developed innovative algorithms for image processing and astrometry, further solidifying his reputation. With over 30 citations on his flagship paper and growing recognition in the field, Choi’s work continues to shape how we observe and protect the orbital environment, making him a key resource for students and researchers interested in applied astronomy and space policy.
