GPS navigation has become an irresistible trend embedded into mobile phone while these powerful platforms would fulfill 3D display functionality in near future. The MEMS technology makes small profile sensor manufacturing possible, which could be integrated into the mobilephone quiet easily. Such integration would enhance the availability and robusticity of navigation solution greatly. The pape...

Backbone connectivity is a critical and challenging problem in vehicle ad hoc networks. Just like base stations in cellular networks, the backbones or mobile base stations in vehicle ad hoc networks play important roles in location management and engineering applications. In this paper, we discuss the one-to-one connectivity by extending the navigation functions, and present the integrated powe...

Navigation and search are two general ways to retrieve information on the web. The usability and utility of web navigation have a direct impact on information seeking efficiency and the success of a website. There are basically two ways to improve web navigation designs. One is to improve the webpage design and content organization of the website; web usability studies have offered plenty of gu...

Preliminary communication Automation of navigation at sea has partly been provided for with the use of integrated navigation bridge − INB. The functioning of INB is supervised by the officer who also takes the final decision during navigation. The complete automation of navigation can be improved by upgrading the existing equipment on board modern ships. To provide for automation of inland navi...

Interactive multimedia (IMM) navigation systems rely on two key non-graphical components, a schematic or architectural framework and an associated programming solution. Two primary framework types are recognized – branching (structured) and referential (unstructured) – although most navigation systems include elements of both. Programmed solutions to navigational frameworks typically display va...

Inertial navigation systems are precise devices that used to measure the orientation and accelerations of a platform they integrated. Accuracy measured data is essential due critical role these systems. The way integrated platform, directly affects accuracy. In this paper, case study alternative designs for Navigation device integration on Tactical Unmanned Aerial Vehicle presented. Mechanical ...

The emphasis of this paper is on MicroBlaze implementation of GPS/INS integrated system on Virtex-6 field programmable gate array (FPGA). Issues related to accuracy of position, resource usage of FPGA in terms of slices, DSP48, block random access memory, computation time, latency and power consumption are presented. An improved design of a loosely coupled GPS/INS integrated system is described...

The LINK-16 standard for military anti-jam digital communications provides Anti-Jam (AJ) communications using Frequency Hop and Pseudo Noise (PN) spreading techniques. As a result, there are accurate time-of-arrival (TOA) measurements between the transmitting terminals. This paper describes the design and development of an integrated navigation filter that is capable of exploiting LINK-16 TOA m...

Low-cost MEMS-based IMUs, video cameras and portable GNSS devices are commercially available for automotive applications and some manufacturers have already integrated such facilities into their vehicle systems. GNSS provides positioning, navigation and timing solutions to users worldwide. However, signal attenuation, reflections or blockages may give rise to positioning difficulties. As oppose...

Providing an accurate and practical navigation solution anywhere with portable devices, such as smartphones, is still a challenge, especially in environments where global navigation satellite systems (GNSS) signals are not available or are degraded. This paper proposes a new algorithm that integrates inertial navigation system (INS) and pedestrian dead reckoning (PDR) to combine the advantages ...
