During Phase I ACS surveyed the assess Non-Developmental (NDI) C41 software for application to IUSS missions. ACS identified a Tactical Decision Aid (TDA) which provides a wide variety of surveillance data collection management functions. These functions include sensor coverage and availability analysis, sensor tasking, communication interfaces, message parsing, world maps and supporting data bases. The TDA is being developed under government sponsorship and will be operational in mid-FY92. ACS has also identified communication software which receives and filters non-organic surveillance data from existing tactical broadcasts. This communication software is planned for operational deployment 2nd QTR FY-92. During Phase II, ACS proposes to tailor, modify and integrate the above identified TDA and communication software into a UNIX based workstation (e.g., DTC-2) environment. This integrated workstation will permit IUSS to better receive, display, evaluate and manage non-organic surveillance data and will provide automated aids to direct non-organic surveillance resources. ACS will test the integrated workstation at the ISUS Development and Test Facility and then support its deployment and evaluation at an IUSS operational facility.
