The region of Balkan Peninsula and in particular, the territory of Bulgaria characterizes with active tectonics and seismotectonics. A number of geological, geophysical and geodetic investigations demonstrate the recent activity of the region, and have tried to give a reasonable…

After years of development, as the representative of GNSS, GPS technology has been gradually replacing the conventional triangulation techniques and has become the main means of access to ground control point coordinates. From the initial decimeter magnitude to the current sub-centimeter or even millimeter level, the coordinate precision of ground points has been highly improved upon…

On the 15th of October 2013 the European GNSS Agency (GSA) released the latest version of its GNSS Market Report. The Market Report brings an updated and enhanced view of the GNSS global market “as it is experimenting rapid developments”. It encompasses a larger scope than before

The main focus of this paper is the spectral and spatial characterization of GNSS jammers with specific emphasis on multi-frequency wideband jammers which are able to simultaneously jam up to three frequencies. The paper extends previous analysis to jammers also operating in the L2 and L5 bands
