Clocking On

Yorkshire clockmaker John Harrison unveiled his first marine timekeeper, now designated as H1, in 1735. It incorporated several innovations that reduced the clock’s susceptibility to a ship’s motions, temperature changes and friction. (Image courtesy of National Maritime Museum; Greenwich, England)

One of the greatest episodes in the history of clockmaking unfolded over three decades during the 18th century in response to a government challenge to … More ››

Taking control

Aircraft positions picked up by ESA's Proba-V minisatellite, using an experimental Automatic Dependent Surveillance – Broadcast (ADS-B) receiver. These signals are regularly broadcast from aircraft, giving flight information such as speed, position and altitude. All aircraft entering European airspace are envisaged to carry ADS-B in the coming years.

Proba-V has picked up upwards of 25 million positions from more than 15 000 separate aircraft. The DLR German Aerospace Center and SES team has identified more than 22 000 unique callsigns, identifying more than 15 000 aircraft by their unique International Civil Aviation Organisation (ICAO) addresses (one aircraft can share a callsign with others, depending on the flight route).

Gerhard Bethscheider, managing director of SES Techcom Services, outlines the development of a dedicated space-based European ADS-B solution. As worldwide commercial air travel continues to … More ››
