Spying on "reconnaissance spacecraft" in geostationary orbit (GEO), is gaining momentum.

Company Astranis building Perceptor spacecraft designed to capture satellite activity in GEO orbits.

FYI, GEO is typically 35,786kms/22,236 miles above Earth ... popular for communications, weather and "reconnaissance" satellites. https://www.space.com/space-exploration/satellites/astranis-perceptor-satellites-geostationary-orbit-space-situational-awareness #Space #Satellite #GEO #GeostationaryOrbit #Perceptor #Astranis #Spacecraft #Reconnaissance #Sensors #OpticalSensors #USSF #EarthObservation #USGov
