About
AFS-X is a two-mirror Cassegrain antenna designed for organizing high-speed radio links for spacecraft. The antenna is lightweight and has the ability to use a second input to organize simultaneous dual-polarization data transmission (RHCP/LHCP). The antenna has successfully completed the NEO (in-orbit/near-Earth-orbit) test cycle.
