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...
Satellite communications are destined to play an important role in future telecommunications infrastructure, thus the increasing interest in transporting Internet traac over satellite links. Many studies have shown that TCP has a poor performance in the context of satellite communications. This is due to many factors inherent to satellite communications and for which TCP originally designed for...
U sers of communications satellites often ignore the actual hardware in space the makes their applications possible. To help fill this gap, we review some recent trends and developments of the kinds of satellites that operators are launching. This is not intended to encompass all of the systems and services that make up the industry, but rather selects some of the more salient elements that can...
