The Department of Defense, specifically the Naval Information Warfare Systems Command (NAVWAR), is seeking to enhance its capabilities by procuring additional Advanced Time Division Multiple Access (TDMA) Interface Processors (ATIP) and associated engineering services. The procurement aims to increase the quantities of ATIP servers and Terminal Interface (TIF) systems, as well as to provide ongoing technical support, software maintenance, and hardware repairs to ensure the extended lifecycle of these systems. These enhancements are critical for maintaining operational readiness and compatibility with future military satellite communication systems.
