SURI

AFRL / AFOSR Space University Research Initiative (SURI)


ֱ Boulder, Texas A&M, and Georgia Tech are jointly performing on aSpace University Research Initiative (SURI) award from AFOSR.


Research

The University of ֱ Boulder (ֱ Boulder), Texas A&M University (TAMU), the Georgia Institute of Technology (Georgia Tech), and industries have teamed to investigate basic research interrogating novel sensor exploitation. The team willinfer internal space object modes, sensor network architectures, the art of the possible in 'beyond geosynchronous orbit' (XGEO) operations and strategies, and human-in-the-loop autonomous systems. New basic research and sensing advances in technically diverse fields such as cognitive engineering, autonomy, decision-making under uncertainty, modern astrodynamics, multi-target tracking and dim object detection are providing a decadal opportunity to address future space domain awareness (SDA) near Earth and beyond.This initiative aims to enable space object identification, proliferated small footprint radio-frequency sensors, dim object detection and tracking, and question-based tactical sensor tasking through the development and transition of technology.
