Portal Space Systems and Rebel Space develop onboard spectrum-monitoring for maneuverable satellites to detect RF interference
Portal Space Systems and Rebel Space are working to add onboard spectrum-monitoring technology to Portal’s maneuverable spacecraft so they can detect and characterize RF interference and electronic threats in orbit, rather than relying only on ground-based sensing. The collaboration could enable real-time attribution, geolocation and potential responses to jamming or suspicious electromagnetic activity for commercial and military satellites.
