ACTIVE AND PASSIVE INTERCEPTION SYSTEM EQUIPMENT
Conventional secondary surveillance radars are gradually being replaced by Automatic Dependent Surveil- lance-Broadcast (ADS-B) systems due to high operational and maintenance costs, stringent installation require- ments, and limited coverage. Given China's vast territory, complex terrain, uneven urban development, and imbal- anced population density, building a comprehensive ground-based ADS-B surveillance network is complex, time-consuming, and still leaves coverage gaps across regions, blind zones, and maritime areas. Satellite platforms, operating at much higher altitudes, can receive ADS-B signals over wide areas. A single spaceborne ADS-B system can achieve large-area coverage, helping to gain real-time situational awareness of civil aircraft over wide expanses.
