Abstract:
The rapid proliferation of space objects and emergence of mega-constellations necessitate advanced space situational awareness (SSA) capabilities. This paper presents VISION (Vigilant Integrated Space Information and mOnitoring Network), a next-generation space information analysis system developed by the Korea Aerospace Research Institute to address New Space era challenges. Building upon 18 years of operational experience since China’s 2007 ASAT test, VISION overcomes limitations of its predecessor CA-FAST through modular architecture capable of processing over 200,000 Conjunction Data Messages annually from multiple sources (CSpOC, LEOLABS, COMSPOC, SAFRAN). The system implements automated multi-source data fusion for 11 different formats, reducing operator intervention to less than 1% while maintaining 24/7 unmanned monitoring for over 100 satellites simultaneously. Key innovations include advanced analytical capabilities beyond traditional collision assessment—maneuver detection, RF interference analysis, orbital anomaly detection—and space security functions addressing noncooperative approaches. The three-module architecture (Space Information Management, Analysis, and Simulation & Visualization) enables horizontal scalability and independent operation. VISION represents a significant advancement in automated space traffic management, achieving operational efficiency through intelligent automation and serving as the foundation for Korea’s national SSA framework. Future work includes domestic surveillance asset integration, machine learning implementation, and expanded international partnerships.
