When the Patriot Missile System needed a boost, SCI Technology developed a life-extending solution.
With demand for Patriot shelters becoming problematic due to parts-obsolescence issues with the platform’s Integrated Digital Operator Control System (IDOCS), SCI teamed up with the customer to resolve the problem quickly and effectively. Drawing on our powerful combination of capabilities and resources, we designed and manufactured a drop-in replacement unit called the Modified Integrated Digital Operator Control System (MIDOCS).
In its existing configuration, IDOCS used individual circuit cards and a backplane to perform its communications functions for the Patriot System. Following SCI’s comprehensive obsolescence-redesign process, MIDOCS employed our MCSU line-replaceable unit and interface card—core components from TOCNET®, our robust tactical communications product line.
With SCI’s modifications in place, the Patriot System quickly returned to full strength, overcoming a critical obsolescence problem that had threatened the program’s viability. Our custom solution not only modernized existing shelters, but also allowed for the production of additional shelters with up-to-date components. We performed all the work—from engineering to production to final assembly—on-site in our 680,000-square-foot facility in Huntsville, Alabama.
MIDOCS maintained all the key features of the existing IDOCS product, including:
With more than 55 years of experience in the defense and aerospace sector, SCI has developed a distinctive combination of resources and expertise that enable us to deliver superior products and services. To meet this customer’s unique and challenging needs, we leveraged our best capabilities for a uniquely effective solution.
In partnering with all of our customers, our Depot & Test segment works seamlessly with on-site engineering and manufacturing assets to make SCI a one-stop shop for each and every point in any product’s lifecycle. The depth of our engineering delivers unsurpassed efficiency, while our breadth of resources offers a clear advantage over the competition.
Backed by the strength of SCI, MIDOCS: Enables digital and analog communication between Patriot shelters via Ultra High Frequency/High Frequency Radio (UHF/HFR), Very High Frequency Single Channel Ground and Airborne Radio System (VHF SINCGARS), Air to Ground Voice Network and Air Defense Coordination Communications. Provides up to 4 operators per shelter access to 5 radios, 2 EO battle circuits, 2 HEU battle circuits, 1 DNVT phone circuit, 1 monitor and intercom functions. Transfers data (RLRIU, FO DTG, packet, phones, FSK modems) over redundant links between shelters and shelter assets. Supports operator control of changeable data paths. Performs diagnostics and reports results.
