Digital Intermediate Frequency Interoperability (DIFI) Consortium

“Why DIFI Matters” with Carmel Ortiz

Our Mission

The mission of the Digital Intermediate Frequency Interoperability (DIFI) Consortium is to enable the digital transformation of space, satellite, and related industries by providing a simple, open, interoperable Digital IF/RF standard that replaces the natural interoperability of analog IF signals and helps prevent vendor lock-in. A truly interoperable digital IF will enable transformation to a virtualized ground segment, reducing the total cost of ownership and significantly boosting network and terminal agility and scalability.

IEEE-ISTO Std 4900-2021:  Digital IF Interoperability Standard, v1.2.0 – August 2023

The data plane interface provides the ability to transmit and receive digitized IF data and corresponding metadata over standard IP networks. This interface is meant to be fully compliant with the VITA 49.2 standards.  To download the Standard, please complete the contact form below.

Membership

The newly formed consortium is in the process of implementing administrative structures and recruiting additional member companies and organizations with an interest in space networks to become active participants in DIFI.  Please review the Governing Documents and join now!
