Herndon, Va., 9 February, 2026 鈥� (iDirectGov), a leading provider of satellite communications to the military and government, today announced the successful live over-the-air point-to-point testing of a DVB-S2X waveform on the 450 Software Defined Modem (SDM) using the company鈥檚 virtualized waveform core (WCore).
The test validated iDirectGov鈥檚 DVB-S2X waveform functionality, stability and interoperability in a real-world radio frequency (RF) environment. Operating on the 450SDM through the WCore, the waveform delivered reliable end-to-end performance, without compromising security. The test demonstrated a 200Mbps x 200Mbps SATCOM link over a Mil-Ka-band spot beam. The 450SDM with the DVB-S2X waveform can support speeds up to 672Mbps x 672Mbps.
鈥渋DirectGov is building a clear implementation path for developers to integrate waveforms on software-defined modems using the WCore, enabling seamless, secure, and interoperable communications,鈥� said Tim Winter, iDirectGov president. 鈥淥ur recent milestone includes successful testing on mid-Earth orbit (MEO), and since WCore is waveform-independent, it is designed to operate seamlessly across geostationary (GEO), low-Earth orbit (LEO), and other multi-orbit constellations, extending our DVB-S2X capabilities for partners and end users.鈥�
The 450SDM uses the WCore interface to securely integrate iDirectGov-hosted and third-party applications through abstraction and virtualization. The WCore can manage and orchestrate multiple waveforms 鈥攗p to 16 on the 450SDM鈥攁nd provides access to additional applications such as AES encryption and iDirectGov鈥檚 Communication Signal Interference Removal (CSIR ) technology.
鈥淟ive RF testing confirms that our satellite modems can support diverse waveforms across multiple constellations in operational environments,鈥� Winter said. 鈥淭his flexibility is essential for defense and government customers who depend on secure, resilient and adaptable satellite communications to meet their evolving tactical communications needs.鈥�
The iDirect Government 4-Series SDMs with the WCore deliver resiliency, security, and optimized size, weight and power (SWaP) for U.S. DOD users, while enabling commercial innovation and development and in particular, where protection of intellectual property is critical.
