CLS, a subsidiary of the French Space Agency (CNES), acting through its new radar applications division (formerly the BOOST Technologies Company), is using the race to demonstrate the ability of Envisat radar imagery to operationally observe oceans at high resolution.
Based on the trajectory and speed of the boats, CLS is acquiring data over the area skippers will be sailing into slightly ahead of their arrival time in order to monitor the metocean conditions.
Although skippers are forbidden to receive outside assistance in the Vendee Globe race, these data will be helpful for skippers planning optimal routes in races where new types of meteorological information will be allowed.
"These innovative techniques providing wind and wave information at unprecedented resolution will certainly be directly transmitted to sailors in other races in the future to help them determine the most appropriate route in challenging regions of fast-changing metocean conditions such as the Canary Islands or the Saint Helene high pressure system," said Dr Fabrice Collard of France's CLS radar application division in Brest.
These wind and wave product demonstrations, originally tested over Europe, are part of an ESA research project on innovative retrieval techniques. The development and processing techniques are being extended to Envisat Advanced Synthetic Aperture Radar (ASAR) data acquired along the Vendee Globe route.
The Vendee Globe takes sailors through severe wind and wave conditions in the Southern Ocean, which is also home to many icebergs. The data used in this test was originally acquired for the purpose of iceberg detection.
The long swells and high winds typical of the Southern Ocean have been clearly identified with a high-resolution variability that may provide new insight for the understanding of complex and remote seas.
As part of the Global Monitoring for Environment and Security (GMES), a joint initiative of the European Commission and ESA, ESA has undertaken the development of Sentinel-1 for the continuation of SAR operational applications.
Dr Vincent Kerbaol, head of the radar application division of CLS said: "This ESA and CLS research demonstration using Envisat data provides an excellent taste of the wind and wave products that will be delivered operationally to the GMES services using the next generation SAR onboard ESA’s Sentinel-1 satellite to enhance the maritime safety and awareness."
CLS will hold a press conference on 16 December 2008 at the Vendee Globe headquarters in Paris where they will present the principles of iceberg detection using Envisat ASAR data. By invitation from CLS, ESA and CNES will participate in the conference.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
