Hardware-in-the-Loop Scintillation Simulator for MILSATCOM links in a Nuclear Disturbed Communication Environment

In response to SBIR Topic DTRA172-006, Welkin Sciences proposes to design and build a new all-digital fading channel simulator to be called CoLTSAD. This new simulator design will be the latest addition to our family of Configurable Link Test Sets (CoLTS). It will be capable of emulating the full range of MIL-STD-3053 scintillating channel conditions for all SATCOM frequency bands up to Ka-band. CoLTSAD will support developmental and acceptance testing of existing communication systems designs using separate analog interface units, and future communication systems compliant with the new FAST OSDI (ANSI/TIA-5041) industry standard for digital-IF modems without analog IF front ends.The CoLTS-AD will be low-cost to build, and low-cost to certify: 1) it will be built on an inexpensive COTS hardware platform; and 2) will include built-in test functions that allow comprehensive certification testing procedures to be executed and tabulated automatically. Automated certification test execution and report generation can be performed after each simulator update or repair, simplifying configuration management and reducing life cycle costs.
