This paper introduces a novel wireless local positioning system (WLPS) and highlights its applications for aircraft relative positioning and spacecraft constellation navigation.
The authors describe a number of aircraft radio sets of a more recent construction.
The first part of the article is devoted to a general discussion of (a) internal communication, (b) communication with outside fixed points and with other airports, (c) communication with aircraft,
HE present development of air transport is bringing out its need for adequate communication in much the same manner as the earlier development of railway operations disclosed for that industry the
During the past decade knowledge-based expert systems, KBESs, have been developed by researchers in artificial intelligence to help solve ill-structured problems.
Al sub x Ga sub 1-x As-GaAs vertical cavity surface emitting lasers on Si are promising GaAs light sources for monolithic integration with Si technology because of their many attractive processing
A new technique for the growth of III-V compounds by molecular beam epitaxy has been developed which uses electron beam heating for evaporating the group III liquid metals.
Migration steps towards a repository architecture to facilitate user-centric data management in the IP Multimedia Subsystem (IMS) and fixed/mobile access domain.
The control equipment has a capacity of 60 stations and 3 alarm groups, a separate alarm circuit being provided for each of 3 watchmen.
The aim of this paper is to investigate new tracks to tackle the open issues of alarm correlation for complex networks (e.g. IP/SDH or IP/WDM).
