ESA engineers are proposing a technique to enable a digital satellite radio service for European drivers - without the need to launch a single new satellite into orbit.
Commercial digital satellite radio is already a reality in the United States, using a costly set of dedicated satellites. The rival American services allow subscribing drivers to choose between numerous near-CD quality radio channels without tune-out or static.
Two parallel ESA studies have examined a lower-cost method of providing in-car Europe-wide satellite radio, along with supplemental text, pictures and video data. ND Satcom (prime contractor), DLR, IMST and SES Astra conducted one of the studies while Alcatel Space (prime contractor), Frauenhofer Gesellschaft, Skygate and SES Astra performed the other.
"This service would include music and voice data," said ESA engineer Rolv Midthassel from the Technology Projects Division of the Telecommunication Department. "Plus additional data could be displayed on-screen such as information on songs, traffic and weather forecasts, and other services dedicated to car drivers."

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.
The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
