DIFI has created a standard that enforces interoperability on digital IF/RF technology. Digital IF was developed to overcome the limitations of analog systems but, today, vendor lock-in prevents it from delivering seamless interoperability and severely limits its adoption. A truly interoperable digital IF, on the other hand, will enable transformation to a virtualized ground segment, reducing the total cost of ownership and significantly boosting network and terminal agility and scalability. Compliance with the DIFI standard will ensure that satellite ground segments can seamlessly adapt to rapidly changing space-layer payloads, orbits, and constellations. Ultimately, DIFI promises to elevate the resilience, performance, and capabilities of satellite networks and enable a digital transformation that integrates satellites seamlessly into the larger telecom, IT and GIS markets.
