Closing The "Integration and Protocol" Gap With Software-Defined Channel Emulation

The transition to Non Geostationary Orbit constellations and virtualized ground infrastructure is redefining satellite communications. Networks are becoming software defined, cloud native, and increasingly complex. Yet validation methodologies remain siloed, testing RF payloads and ground modems in isolation.

This creates a critical integration gap. End to end latency, handover logic, Doppler effects, and synchronization protocols are often not fully validated until the network goes live. In a dynamic multi orbit environment, static hardware centric testing tools cannot replicate real world conditions at scale.

This ABI Research whitepaper examines how software defined channel emulation bridges the divide between the space segment and the ground segment. It outlines a unified approach to testing that connects RF physics, digital intermediate frequency, virtual modems, and cloud native infrastructure in a single loop.
