NIST helps beam time to TV viewers in the Middle East

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: ILA 2018: Laser alternative to hexavalent chromium coating

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...

Im Focus: Radar for navigation support from autonomous flying drones

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
