Balloon-borne air traffic management (ATM) as a precursor to space-based ATM

► Increasing air traffic calls for global air traffic monitoring (ATM). ► Flying proven technology (ADS-B) on satellite constellation can provide global ATM. ► I-BATE tested space-based ADS-B reception from stratospheric balloon (∼30 km altitude). ► I-BATE received ADS-B messages from near-space environment. ► Space-based ADS-B reception a viable solution for global ATM, needs further research.
