About
The CubeCAT is an S-band communication system from AAC SpaceQuest providing high-rate downlink for CubeSat missions requiring more bandwidth than UHF/VHF can provide. It is designed for Earth observation, remote sensing, and other data-heavy applications where efficient downlink of large image or data files is needed. The system includes an integrated S-band transmitter, patch antenna, and diplexer, and supports data rates up to several Mbps.
