Army Awards SBIR Phase I to Welkin Sciences

November 9, 2016 — Colorado Springs, CO — The U.S. Army at Redstone Arsenal, AL, has awarded a Phase I SBIR contract to Welkin Sciences to explore a Reprogrammable Software Radio (RaSoR) to augment the Multi-Mission Launcher (MML) concept by providing flexible missile data link equipment capable of supporting the various missiles planned for the MML.


First Successful Demonstration of Digital IF Long-Haul Transport for ANSI/TIA 5041 Standard

October 6, 2016 — Germantown, MD — The first successful demonstration of the transport of a SATCOM waveform over the commercial Internet was conducted today between Maryland and Idaho. The demonstration was achieved using equipment compatible with the ANSI/TIA 5041 Standard: Future Advanced SATCOM Technology (FAST) Architecture Open Standard Digital IF (OSDI) Interface. While testing involved SATCOM-type waveforms, the demonstrations included no over-the-air transmissions.

The testing was conducted by an industry team that included Comtech EF Data, AHA Products Group (part of Comtech EF Data), and Welkin Sciences. Brocade supplied multiple 10 GbE switches for all locations supporting the testing and demonstration. The effort tested, evaluated, and demonstrated packet loss through the commercial Internet and showed how and why forward error correction (FEC) is required for operation. Welkin Sciences’ Digital IF Firmware core was used to implement ANSI/TIA 5041 compliant Digital-IF interfaces in the Comtech EF Data CDM-930 Digital IF modem. The Welkin Sciences’ Legacy Modem Data Converter was used to convert the Comtech EF Data CDM 760 L-Band IF signals to an ANSI/TIA 5041 compatible Digital IF stream.

The FAST OSDI (ANSI/TIA 5041) capability is highly advantageous to the DoD:
• Because it allows for SATCOM continuity of operations (COOP),
• Provides the DoD with operational flexibility for satisfying many SATCOM missions from any FAST OSDI compatible satellite terminal,
• Supports elimination of large expensive analog switching/combining systems with cheaper digital switching systems.

Army Taps Welkin Sciences to Commercialize FAST Technology with $9.9M Phase III Contract

July 30, 2014 — Colorado Springs, CO — The US Army Communications Electronics Research & Development Engineering Center (RDECOM CERDEC) awarded Welkin Sciences a $9.9M, five year SBIR Phase III contract to commercialize prototype products developed during Phase II contract for the Future Advanced SATCOM Technologies (FAST) program.

Welkin Sciences participated in a government/industry workgroup to develop the industry standard FAST Open Standard Digital IF Interface (OSDI). The FAST OSDI standard allows independent vendors to develop components for a Digital IF architecture that will interoperate together. According to the CERDEC FAST Program Manager, Herald Beljour, “The Digital IF architecture and open interface standard will allow the government to modernize and upgrade SATCOM communications in a competitive fashion without locking in to one particular vendor. Digital IF technology enables more flexible switching and routing while also improving signal fidelity and reducing operation costs.”

Welkin Sciences is focusing its product development efforts on a Digital Conversion Subsystem (DCS) to convert L-band signals to Digital IF streams, and a Wideband Signal Processor (WSP). The WSP processes quadrature baseband signal samples for compatibility with digital modems (DM) and/or legacy analog-IF modems connected to a Digital IF converter. On transmit the WSP aggregates signals from a large collection of input baseband carrier signals. Connection to DCS and DM units is supported by high-speed Ethernet fiber.

During the Phase III effort Welkin Sciences will be working with partners Comtech EF Data and Harris Corporation GSCD who are developing digital modems in order to demonstrate the multi-vendor interoperability of the architecture.
