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!
Electronically-steered flat-panel antennas (ESAs) are on a clear evolutionary path from high-cost terminals for single-beam/single-use applications to increasingly affordable offerings, many with some combination of multi-beam, multi-band, and multi-orbit capabilities. Supporting these flexible antenna systems will drive demand for digital-based ground systems for signal routing and processing. The DIFI Consortium is taking up the challenge of setting up and managing services through these antennas in a way that will enable interoperability between antenna systems and digital ground systems.
