We compare the overall structure of military GIG and NCES architectures with that of the object oriented architectures (CORBA, J2EE and .NET) and of the emerging Web Services architecture. While the match is good in many ways, particularly with respect to Web Services, we also identify a series of shortcomings that could stymie attempts to implement a GIG or NCES system directly on a commercial...

In order to successfully support current and future US military operations in coastal zones, geospatial information must be rapidly integrated and analyzed to meet ongoing force structure evolution and new mission directives. Coastal zones in a military-operational environment are complex regions that include sea, land and air features that demand high-volume databases of extreme detail within ...

The quality and reliability of plastic-encapsulated microcircuits (PEMs) manufactured today are closely equivalent, and in some ways superior, to their hermetic counterparts. The key to reliable use of PEMs in military applications is gained by matching the capabilities of PEMs to the application environment. The intent of this paper is to address the guidelines for achieving these ends by summ...

A new navigational signal designated as L5 with a center frequency of 1176 MHz and a bandwidth of 20 MHz has been introduced as part of GPS Modernization. This new signal is in the Aeronautical Radio Navigation Service Band and will primarily benefit aviation users by allowing precision navigation when used with the existing L1 signal for ionospheric corrections. In addition, U.S. military user...

Wireless Sensor Network is widely used in Military Applications like Tracking the enemy movements and force protection. Security is the major concern and very difficult to achieve due to the unattended nature, limited memory, and limited power of network. This paper is mainly intended to describe the implementation of the secure unmanned Vehicle Navigation system controlled by wireless sensor n...

wireless sensor networks (wsns) have many applications in the areas of commercial, military and environmental requirements. regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. a basic approach for preparing a secure wireless communication in wsns, is to propose an efficient cryptographic key management protocol be...

Augmented reality (AR) has recently stepped beyond the usual scope of applications like machine maintenance, military training and production, and has been extended to the realm of entertainment including computer gaming. This paper discusses the potential AR environments offer for embodied animated agents, and demonstrates several advanced immersive content and scenario authoring techniques in...
