Abstract： Driven by the urgent need for“comprehensive，timely，and accurate”oversight of both space-borne andterrestrialradio stations，this paper introduces-for the firsttime-a Very-Low-Earth-Orbit （VLEO）constellation as a next-generation space infrastructure for spectrum monitoring.We propose a holistic architecture of“multisatelite intellgent cooperative spectrum sensing”that capitalizes ontheunique orbital advantages of VLEO satelites operating at 250～300km altitude： they reside in the near-front-end of downlink beams from satellites in medium， high， andgeostationaryorbits，whiletheircloserproximitytoEarthyieldsdramaticallylowerfree-spacepathlossThroughonboardintelligent proceingadigspeedintesatelitelnks，tearitetureenabesratie，on-bitdatafusioacoss distributedsatelites，delivering instantaneous detection，localization，andtrend predictionofanomalousspectrumusage.
