Flush with voluminous databases of varied geospatial imagery and data, the National Imagery and Mapping Agency is equipping its customers with both reach-back capabilities and on-location expertise. The agency is tapping diverse sources of digitized imagery and terrain data so that it can generate multidimensional products for customers at all levels of government and the military.

The types of sonars equipping Chinese warships are a barometer of Chinese naval technology and antisubmarine capability. The evolution of Chinese sonar from old Soviet equipment to series production, to indigenous designs, to French examples and finally to modern Russian vessels with sonar suites parallels Chinese naval progress. Just as these systems have grown from secondhand gear to indigenous designs supplemented by up-to-date foreign technologies, so has the Chinese navy transitioned to a force designed to serve the nation's maritime needs.

Although industry shoulders the ultimate responsibility for the health and well-being of the U.S. telecommunications infrastructure, the federal government is working to ensure the continued operation of systems that touch almost every aspect of life-from emergency services to economic stability. Key among the government's concerns are the security and reliability of the systems on which national security and emergency preparedness depend.

The future role of information technology in support of homeland security and the war on terrorism initiatives will be the focus of TechNet International 2003, May 6-8. In its new venue-the recently opened Washington Convention Center, Washington, D.C.-AFCEA International will offer three days of information presentations and technology demonstrations in an integrated setting.

The National Imagery and Mapping Agency is in the midst of a pivotal year as it creates its own functional identity as the geospatial intelligence provider for military and homeland security organizations. The agency will be looking for substantial support from the commercial sector-including foreign companies-while it transforms and concurrently meets the growing needs of the defense community.

Having effective sensors, fire control, ordnance and control systems is only part of the picture for building a capable shipboard combat system. The task that makes all of these play together is called combat system integration, or CSI.

Manufacturers are poised to release new equipment that will permit universal roaming for cellular telephone and mobile devices. Recent processor and software developments are leading to products that can operate across different global communications protocols.

Emergency responders now can count on priority cellular access in a pinch as the U.S. government establishes a wireless version of its Government Emergency Telecommunications Service. Known as the Wireless Priority System, or WPS, the new cellular system promises connectivity in a shirt pocket for authorized users ranging from the president down to a local fire chief.

By co-locating its intelligence and operations communities under one high-technology roof, the U.S. Marine Corps I Marine Expeditionary Force can now manage multiple missions from a single command center. Systems at the facility allow decision makers to review and analyze information pouring in from tactical network sensors and help the Marines plan and execute military operations, ensure base security and support localized efforts such as fighting forest fires.

Future commanders may benefit from an enhanced situational awareness and battlefield management system that fuses sensor and information feeds to create a coherent picture of an engagement. The system will permit data to be relayed, shared and analyzed by allied joint forces across multiple echelons.
