What Welkin Sciences does

Welkin Sciences is a privately held small business founded in 2003 in Colorado Springs, Colorado by two engineers with deep expertise in digital signal processing and satellite communications. The company develops two complementary product lines: DIFI-compliant Digital Intermediate Frequency (Digital IF) products that transport RF signals over digital optical fiber using Ethernet packet switching, and hardware-in-the-loop (HWIL) channel simulators and jammer emulators used to test protected military satellite communications against wartime threats such as nuclear scintillation and jamming. Its product portfolio includes the DIVA-D vector analyzer, DCS-D conversion subsystem, DIFI IP Firmware Core for AMD/Xilinx platforms, and the MASS, CoLTS-LC, CoLTS-ACE, and CoLTS-AE simulator family, with bandwidths up to 500 MHz and DTRA-approved channel models compliant with MIL-STD-3053.

The firm pioneered the FAST OSDI Digital IF standard and is a member of the DIFI Consortium advancing IEEE-ISTO Std 4900-2021, positioning its products as open-standards reference implementations. Customers are concentrated in U.S. Department of Defense agencies (DTRA, MDA, U.S. Army, Air Force, Navy) and defense prime contractors (Lockheed Martin, Raytheon), with selective engagement in commercial SATCOM (ViaSat). Technical support is delivered directly by the engineers who designed the products, including on-site training.

Welkin generates revenue through one-time hardware sales of off-the-shelf and customized products, licensable IP/firmware cores, and professional R&D and engineering services that include rapid prototyping and specialized programming for FPGAs, GPUs, and multi-core CPUs. Products are procured through the U.S. GSA Schedule, with multi-year contracts and quote-based pricing for custom solutions. The company self-describes as having a high rate of SBIR commercialization and operates with 11–50 employees under founder-majority ownership.

Core offering

Welkin Sciences designs, manufactures, and supports digital intermediate frequency (Digital IF) hardware products and hardware-in-the-loop channel simulators/jammer emulators used to test military and commercial satellite communication systems. The company also provides custom R&D and engineering services, including rapid prototyping, firmware/IP development, and specialized programming for multi-core CPUs, GPUs, and FPGAs.

Product overview

Welkin Sciences offers two complementary product lines: Digital IF products and Channel Simulators/Jammer Emulators. The Digital IF product line includes the DIVA-D (test and measurement equipment for DIFI-compliant devices), DCS-D (digital conversion subsystem for L-band interfaces), and DIFI IP Firmware Core (for modem developers). The Channel Simulator line includes MASS (MILSATCOM Atmospheric Scintillation Simulator), CoLTS-LC, CoLTS-ACE, and the latest CoLTS-AE (supporting 500 MHz bandwidth). Both product families comply with the DIFI Standard (IEEE-ISTO Std 4900-2021) and support DTRA-approved channel models for nuclear scintillation testing.
