Net-centric adapter for legacy systems (NCALS) is a software technology that makes legacy system data and services available in near real-time to the global information grid (GIG). The intent of NCALS is to lower the cost and risk, and to decrease the time required for legacy systems to comply with DoD net-centric technical standards. Many different systems could use a common, configurable NCALS software...
