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

Welkin Sciences proposes to design and build a new fading channel simulator to be called the All-Digital Configu­rable Link Test Set (CoLTS–AD). It will be capable of emulating the full range of MIL-STD-3053 scintillating channel conditions needed to test all of DoD’s strategic communication systems. CoLTS–AD will support developmental and ac­ceptance testing of conventional communication sys­tems with analog IF or RF signal ports, as well as future communication systems compliant with the new FAST OSDI (ANSI/TIA-5041) industry standard for digital-IF modems. Our proposed CoLTS-AD will be designed for both a low build cost, 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.
