Full-duplex capability is a significant advantage. While sending large data files down to Earth (downlink), the satellite can simultaneously receive commands or configuration updates from a ground station (uplink). This prevents transmission bottlenecks and allows for more dynamic and responsive mission operations.

HYPSO-2 is a 6U CubeSat designed for hyperspectral imaging of ocean environments. It features a software-defined communication payload and needs to downlink vast quantities of image data back to Earth. The mission will be equipped with a .

The Satlab SRS-4 transceiver balances high-throughput capabilities with the strict power and weight budgets required by CubeSat platforms.
