The Joint Cross Domain eXchange (JCDX)

Formerly OSIS


The Joint Cross Domain eXchange (JCDX) program is a multilevel secure (MLS) intelligence and target tracking framework that provides early warning of potential threats on a global scale.  JCDX is installed at numerous sites worldwide.


Formerly known as The Ocean Surveillance Information System (OSIS) Evolutionary Development (OED) program; the program is a shore-based intelligence system providing on-line, automated, near real-time, netted command-and-control support to the Unified Commanders-in-Chief, Joint Task Force commanders afloat and ashore, individual ships, and allies. It receives, processes, and disseminates timely all-source surveillance information on fixed and mobile targets of interest both afloat and ashore. OED provides a multi-level secure system at the message level and automated event-by-event reporting. OED is evolving toward a Global Command and Control System-Maritime (GCCS-M)-compliant system, and employs GCCS-M software and hardware (TAC-X series) while retaining all the functionality of the OBU system.


OED provides for the analysis of multi-source intelligence to produce comprehensive reports of foreign forces and potential hostile activity. It also provides near-real-time all-source fusion, correlation and analysis tools, and directly feeding automated reporting capabilities. OED maintains characteristics and performance data on weapons platforms, collecting non-organic data from ashore and afloat sensors, and developing an all-source tactical picture. This data is disseminated to the operating forces for tactical threat warnings, decision making support, and support of Over-the-Horizon-Targeting.


At present the OED System operates in a Sensitive Compartmented Information Facility (SCIF) and requires that all direct users (locally connected via keyboard or network communications) be cleared to the same level as the highest classification of data resident within the OED system. The OED System can provide indirect user’s automated data feeds from unclassified to the system high watermark, which includes full-duplex General Service (GENSER) and Sensitive Compartmented Information (SCI) connectivity. All input to the system is assigned an appropriate classification label to ensure the proper storage, processing, and dissemination (manual and automated) of that information at the designated classification level.


The OED System servers correlate received reports to form tracks (a track being some set of reports that a correlation algorithm has declared are the same physical entity). The tracks are stored in the multilevel track database, which is accessed by the analyst to generate a tactical picture on an area of interest. The multilevel track database maintains the label of the information at the contact report level so that tracks can be distributed with different classifications, compartments, and handling instructions.


Installation of OED was completed at the Atlantic Intelligence Command, the Primary Joint Headquarters (PJHQ) in Northwood, UK. Seven U.S. and allied ( United Kingdom, Japan, and Australia ) sites received the OED hardware and software suite. U.S. sites include: Atlantic Intelligence Center (AIC) at USACOM Headquarters; Joint Intelligence Center-Pacific (JICPAC) at U.S. Pacific Command (USPACOM) Headquarters; JICPAC detachment (J-DET) Yokota Air Force Base, Japan; and Joint Analysis Center (JAC) Molesworth, United Kingdom. The initial OED site for the Republic of Korea Navy was installed in FY 1999.
