NIST helps beam time to TV viewers in the Middle East

14.12.2007
Millions of satellite television and radio users in North Africa and the Middle East can now see and hear the precise time of day, thanks to technical assistance and a custom-built time signal generator from the National Institute of Standards and Technology (NIST).

The new system, which began broadcasting time data and audio reports this year,* is the most widely available source of atomic time in the region. Previously, smaller numbers of users have had access to an automated computer time service (also designed by NIST) and the Global Positioning System, a military satellite service that provides time signals to civilian users with GPS receivers. Now, users of commercially available satellite dishes and receivers can get atomic time by decoding a standard time code format or listening to the audio broadcast.

NIST provided assistance to the National Institute for Standards in Egypt, which negotiated for a special channel for the new service from the Egyptian Satellite Company (NILESAT). NIST built the time code generator, about the size of a briefcase, which produces two signals, a standard time code and an audible seconds pulse and top-of-the-minute voice announcement in Arabic. The time code includes Daylight Saving Time corrections as well as leap year and leap second warnings. NIST and Egyptian standards officials recorded the voices (“At the sound of the tone, the time will be [hour and minute] Egyptian Local Time.”).

The NIST device, installed at a satellite uplink facility in 6th of October City, Egypt, synchronizes its reports with a cesium atomic clock at the same location that is itself synchronized with Coordinated Universal Time to provide traceability to international time standards. According to John Lowe of NIST, Egyptian officials also plan to use the new service to mount time displays in public places. The project was funded by a grant from the U.S.-Egypt Joint Science and Technology Program.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
