NRO Orion sats are probably the largest antennas ever in space (100m). "These satellites at geostationary orbits collect radio emissions (SIGINT) and act as replacements for the older constellation of Magnum satellites. The satellites have estimated mass close to 5,200 kg and very large (estimated 100 m diameter) radio reflecting dishes." https://en.wikipedia.org/wiki/Orion_(satellite) |
