in this paper, an interference management for multi-beam satellite network to enhance spectral efficiency is studied. first, a two-satellite for future generation satellite network using cognitive radio technology is provided.this network is composed of a secondary satellite and aprimary satellite where the primary satellite system does not suffer from severe destructive interferences coming fr...

Summertime continental shallow cumulus clouds (ShCu) are detected using Geostationary Operational Environmental Satellite (GOES)-16 reflectance data, with cross-validation by observations from ground-based stereo cameras at the Department of Energy Atmospheric Radiation Measurement Southern Great Plains site. A ShCu cloudy pixel is identified when GOES exceeds clear-sky surface a detection thre...

This paper presents the design and simulation of a typical Ka band satellite beacon receiver for propagation experimentation. Using satellite beacon signal as a reference signal in satellite wave propagation study, is one of the most important methods. Satellite beacons are frequently available for pointing large antennas, but such signals can be used for measuring the effect of natural phenome...

In the present Mobile Telecommunications scenario, the transmission of SS7 signalling on traditional TDM circuits is evolving to a SS7 over IP network (SoIP) solution, due to the continuous efficiency research in optimizing transmission and to the continuous goal of cost reduction. Some operators are using SoIP network in a national environment, while international SoIP networks are going to be...

The hyperspectral satellite EnMAP (Environmental Mapping and Analysis Program) is scheduled to launch in 2014. It is a joint project by the GFZ (Deutsches GeoForschungsZentrum), the DLR (German Aerospace Center), Kayser-Threde and OHB-System. Apart from the project management, the DLR is responsible for the development of the ground segment for EnMAP. One of the key steps of the developed proce...
