RF Simulation

RF Sim is a software radio automation framework that allows users to simulate their SDR designs in the cloud in a highly scalable, GNU Radio-based, virtual channel emulation environment. It allows users to provide containerized SDR designs and instantiate them in a simulated RF environment. RF Sim can simulate the propagation of RF emissions from each antenna to all other antennas according to a set of user-specified, time-varying channel files. This includes effects such as propagation loss, multipath, time delay, doppler shifts, etc. These simulations are highly scalable and support full mesh connectivity topologies of hundreds of nodes in real time.


Azure Orbital

Azure Orbital is Microsoft’s Ground Station as a Service (GSaaS) which uses the flexibility and configurability of cloud-based, software defined ground station modems to interoperate with a wide variety of spacecraft without requiring an extensive collection of custom hardware.

Azure Orbital lets you communicate, control, process data, ​and scale your operations directly in Microsoft Azure.


Digital IF Interoperability Consortium

The goal of the Digital IF Interoperability (DIFI) Consortium is to provide a simple, open, interoperable Digital IF/RF standard that matches the interoperability of analog IF signals. DIFI's mission is to enable the digital transformation of the space, satellite, and related industries.

Structure: IEEE ISTO Standards Consortium

​Board, Corporate, Gov & NPO memberships available​

First standard approved by board: ​

IEEE-ISTO Std 4900-2021: Digital IF Interoperability Standard, v1.0 – Aug 18 2021​

VITA-49.2 based open digital IF standard​
