SBIR-STTR Award

To meet the goals of SBIR topic MDA10-003, Welkin Sciences proposes to upgrade three important tools needed by DoD's strategic communications community: 1) the CommLink computer simulation used to analyze and evaluate scintillation hardening techniques by DoD scientists and contractors early in a transceiver's development cycle; 2) the CommLink Defined Transceiver (CDT) used by DoD contractors as both a rapid prototyping hardware platform and a rack-mount software defined radio system; and 3) the Configurable Link Test Set (CoLTS) fading channel simulator used for developmental, acceptance and production testing of scintillation-hardened communication systems. These three products need only be enhanced to support the goals of large bandwidth and multiple carriers explicitly described in the topic description. The current capabilities of CommLink, the CDT and CoLTS satisfy the other goals addressed in the SBIR topic description, and these capabilities will all be retained in the upgraded implementations.

To meet the goals for SBIR topic MDA10-003, Welkin Sciences, LLC will upgrade three important tools needed by DoD's strategic communication: 1) the CommLink computer simulation code; 2) the CommLink Defined Transceiver (CDT) software defined radio and prototyping platform; and 3) the (CoLTS) fading channel simulator. The electronic warfare capability of all three tools will be enhanced and the Common Hardware Architecture supporting the latter two tools will be upgraded with faster digital processors and wider-bandwidth data converters allowing the CoLTS to be used for L-Band applications.
