About

Phong Ngo is a leading researcher in ultra-wideband (UWB) radio frequency tracking systems, with a career focused on developing high-precision positioning technologies for NASA’s most demanding space exploration environments. His primary research areas include UWB time-difference-of-arrival (TDOA) and angle-of-arrival (AOA) localization, proximity tracking, and autonomous navigation systems. Ngo’s most significant contribution is his pioneering work on a prototype UWB 3D proximity tracking system at NASA Johnson Space Center, designed to track lunar and Mars rovers and astronauts during early surface exploration missions—a system detailed in his most-cited paper (14 citations). He also led the design of a UWB tracking system for the Mini-AERCam, a free-flying robotic camera that assists with surveillance around the International Space Station. His research into angle-of-arrival triangulation methods further advanced the field of non-GPS localization. With a career spanning over a decade at NASA, Ngo’s work has directly enabled safer, more precise navigation for both crewed and robotic space operations, laying critical groundwork for future Artemis missions and beyond.
