Remotely acquired data using the Landsat satellite system provide a means for initiating crop growth simulation models and crop phenology models at a field level over a large geographic area. A model based on Landsat spectral data has been developed that estimates a spectral emergence of the crop at a pixel(field) level. This spectral emergence date is evaluated using dates of planting and emergence reported by farmers for their fields or spring wheat(Triticum aestivum L.) and barley(Hordeum vulare L.) located in North and South Dakota. The model can provide a means of understanding the distribution of crop emergence across all pixels of a region. This knowledge of emergence date of spring grains from satellite data provides an ability to run crop development and yield prediction models at field level.  1, fiche 1, Anglais, - spectral%20emergence%20date

Le fait de planter lorsque la température du sol est presque optimale accélère la germination et l’émergence des semis. Parfois, dans la précipitation des plantations de printemps, les graines sont semées dans des sols trop froids.

Though mitigation policies are being put in place, it appears that the only sustainable solution would be to actively clean the near-Earth orbits. For the last decade, political, economic and legal obstacles have been slowing down the implementation of space debris removal.... Most of the objects are less than 1 cm(0. 39 inches) in diameter. This also includes dust from solid rocket motors, paint chips and other small debris that flaked from satellite systems. Many systems that include nets, large sails and other structures are only effective for objects that can be grasped and provide poor capture of on-orbit debris for subsequent de-orbit and, indeed, can be damaged by other impacts, contributing to the debris problem on orbit.  4, fiche 3, Anglais, - space%20debris%20removal

Record number: 14, Textual support number: 1 CONT

Overview of resampling methods. From the perspective of space, a satellite camera or sensor takes images that provide unique Earth information at scales ranging from very small to very large. To better understand an image, its shape, scale and perspective often are changed by rectification, orthorectification or map projection to relate it to real world coordinates. During that process, however, gaps between pixels may form, requiring that images be resampled to fill in those missing pixels. There are basically 3 methods of resampling : nearest neighbor, bilinear interpolation and cubic convolution.  4, fiche 14, Anglais, - resampling

In other cases, the instrument could remain locked on water while the satellite is well ahead of the water body, since the reflected signal on water has more power than the reflected signal on land. This may cause a geometric error that could reach several meters for some regions.

Every ten-hour orbit... yielded a set of 2000 one-dimensional star positions covering one great circle on the sky. In the data analysis process, these results were calculated from the raw satellite data,... until enough circles are available to carry out step 2 of the three-step procedure. This involved the interconnection, and interlocking, of a large number of such circles, obtained over a period of a few months-this is referred to as the "sphere solution" step in the Hipparcos terminology.  2, fiche 24, Anglais, - sphere%20solution

Deux projets futuristes restent à l'étude : le projet Quasat proposé par la NASA et l'ESA et le projet Radioastron des Russes, qui font tous deux appel à la mise en place d'une antenne en orbite terrestre réalisant une interférométrie avec les antennes sur Terre. Enfin, dans le futur, il n'est pas exclu de voir un jour la mise en place d'un gigantesque interféromètre constitué d'antennes de plusieurs diamètre en orbite dans l'espace.  1, fiche 25, Français, - projet%20Quasat

Orbiting Astronomical Observatory(OAO), series of four orbiting observatories launched between 1966 and 1972 by the National Aeronautics and Space Administration(NASA) to provide astronomical data in the ultraviolet and X-ray wavelengths filtered out by the earth's atmosphere. Only two of the four launches were successful, however. OAO-2, launched in 1978, which carried two large telescopes in addition to a cluster of four ultraviolet telescopes, four photoelectric telescopes, and a number of spectrometers and other devices, weighed 4, 200 lb(1, 900 kg) and was the heaviest satellite orbited to that time. Working primarily with ultraviolet radiation, it was able to photograph very young stars. OAO-3, which was also called Copernicus, was launched in 1972. Carrying what was at that time the largest telescope ever orbited and three smaller X-ray telescopes, OAO-3 was primarily used in the study of ultraviolet radiation from interstellar gas and dust and from stars near the edges of the Milky Way.  2, fiche 26, Anglais, - Orbiting%20Astronomical%20Observatory

The Polar Orbiting Earth Observation Mission(Poem-1), which is a large satellite for the monitoring of the environment scheduled to be launched in 2000. The objective of the Polar Orbiting Earth Observation(Poem-1) is to develop and build a new satellite platform to accommodate Earth Observation Instruments and supply them with the necessary energy. It is important to build a satellite platform because the lifetime of a satellite is limited and because the continuity of measurements, which is of primary importance to monitor the evolution of our environment and potential climate change, can be ensured only by flying a succession of satellites.  1, fiche 27, Anglais, - Polar%20Orbiting%20Earth%20Observation%20Mission

Car navigation systems are not a novelty, rather there are more and more cars equipped with GPS(Global Positioning System) navigators. The new Travelpilot RNS 149 is the first Blaupunkt car radio with built-in navigation system. All components have been miniaturised in a device incorporating AM/FM RDS radio, CD audio player and navigator with a large graphic display. The Travelpilot can adjust automatically and the tachometer signal provides it with the distance covered; this measurement is constantly compared with the road network stored on the navigation CD, keeping constantly in touch with the GPS satellite network.  1, fiche 30, Anglais, - navigation%20CD
