WITH THE WARFIGHTER Joint space operations center (JSpOC) mission systems (JMS): An acquisition category I program providing command and control (C2) capabilities for space and replaces multiple legacy systems with sustainable hardware and open, evolvable software architecture. JMS is an integrated, net-centric space situational awareness and C2 capability that rapidly detects, tracks, and characterizes objects of interest, identifies/exploits traditional and non-traditional sources, performs space threat analysis, and conducts C2 of space forces in dynamic environments. Throughout the development and validation cycles, our engineers and scientists interact with the JSpOC mission personnel at Vandenberg Air Force Base to validate system requirements, system usability, and operational assessment prior to new capability cutover.Once fielded, SSC Pacific will support the sustainment of JMS and provide user support in future integration efforts with other netcentric space sensor and C2 capabilities.
