Satellite Communications
We are delighted to bring to you this special issue on satellite communications, which we have prepared as part of the spreading of excellence remit of the satellite communications network of excellence (SatNEx). The SatNEx project, which began in 2004, is funded for five years under the Euro-pean Union's Sixth Framework Programme (FP6) Information Society Technologies (IST) Thematic Area. Led ...
متن کاملInter-Satellite Communications for Small Satellite Systems
Small satellite technology has opened a new era in aerospace engineering by decreasing space mission costs, without greatly reducing the performance. The concept of formation flying using small satellites is becoming popular because of their potential to perform coordinated measurements of remote sensing space missions. The current state of art in satellite communications is a one hop link betw...
متن کاملExperimental Satellite Quantum Communications.
Quantum communication (QC), namely, the faithful transmission of generic quantum states, is a key ingredient of quantum information science. Here we demonstrate QC with polarization encoding from space to ground by exploiting satellite corner cube retroreflectors as quantum transmitters in orbit and the Matera Laser Ranging Observatory of the Italian Space Agency in Matera, Italy, as a quantum ...
متن کاملSecuring Satellite Communications
This paper presents securing satellite communications using link level security (such as ATM security) or network level security (such as IPSEC), where both can be applied to military satellite communications. The paper examines the topic of securing very large multicast groups over satellites, where the group size and group dynamics have great impact on networks performance and network security.
متن کاملSatellite - Enhanced Personal Communications Experiments
As an initial step in exploring the opportunities afforded by the merging of satellite and terrestrial networks, Bellcore and JPL conducted several experiments utilizing Bellcore’s experimental Personal Communications System, NASA’s Advanced Communications Technology Satellite (ACTS) and JPL’s ACTS Mobile Terminal. These experiments provided valuable information on the applications, interfaces,...
