This report results from a contract tasking Politecnico de Torino as follows: B. TECHNICAL PROPOSAL/DESCRIPTION OF WORK: Aim of the project is to fabricate and characterize rare earth doped soft glass optical fibers for fiber lasers emitting at wavelengths longer than 2 micron to allow efficient narrow linewidth emission in the atmospheric window useful for coherent detection and sensing. The research activity will focus on the design of the laser ...
Even if recent developments, both technical and political, are affecting the satellite GPS and GLONASS navigation systems, along, in conjunction, or with a possible civilian overlay via INMARSAT or other satellites, the time proven that Loran-C can be still a viable solution for many problems. The aims of this paper are twofold, to present a panorama of the most recent developments in the World and mostly in Europe, and to ...
