A classified US government satellite in geostationary orbit. Based on orbital parameters and published information, analysts assess USA-134 is likely in the Mentor/Advanced Orion class — large, highly capable signals intelligence satellites that collect electronic emissions from fixed positions above the equator. Mentor satellites can unfurl enormous antenna structures up to 100 meters across that intercept satellite phone calls, radar emissions, and microwave communications across entire continents.
