The "SRS-4 / SatLab" type configuration is a prime example of the . It represents a move away from heavy, expensive, analog-centric infrastructure toward flexible, software-defined, cloud-native operations. The value proposition is no longer about who has the biggest dish, but who has the most agile software stack to process the data.
It includes a safe, on-orbit software upgrade mechanism. Operators can load newer firmware images directly to the radio while in space, extending the operational life of the mission.
