Autonomous orbit determination of satellite formation is considered using the measurements between two satellites. This system can accomplish autonomous navigation by using radio cross-link to measure the relative range and optical devices to measure the relative bearing between the two satellites. With the assumption that one satellite knows its attitude information in the inertial reference frame,...
Mobile ad hoc network is a special peer-to-peer network with a wide range of application that has no infrastructure, multi-hop, self-organizing, dynamically reconfiguration and mobile. People are now paying more and more attention to the using of ad hoc network in the emergence area such as battlefield and disaster rescue. The research on its energy and security are one of the most important aspects...
The location technology in wireless sensor network (WSN) is always the focus of research scholars at home and abroad. Based on an improved simulated annealing algorithm, this paper presents a novel WSN node localization algorithm. And the basic principle and the implementing approaches of the algorithm are emphatically introduced. Simulation results demonstrate that good position performance is achieved...
Particle filtering is one of the most important and common tracking algorithms in WSN tracking system. The calculation amount of the particle filter is large while the calculation ability and energy power of the WSN nodes are very limited. In some circumstances, in order to improve the real-time ability and decrease the energy consumed of the tracking system, it is appropriate to reduce particles...
The topic of this review is a summary of the photonics research currently performed at the Material Science and Chemical Engineering Department at Politecnico di Torino, with an emphasis on novel tellurite glasses and nanocluster doped silica for photonics. The fabrication and characterization of novel tellurite glasses and their optical fibers, with the aim of obtaining laser sources operating in...
