Second generation S/C featuring an additional service module for passenger payloads (5 year design life instead of 3). In analogy to the previous SPOT-4 Take 5 experiment, within this timeframe a new experimental phase should allow placing SPOT-5 in a 5 days cycle orbit. The Danish city is a good model in terms of urban planning and design, and is working towards becoming carbon-neutral by the year 2025. Currently, an operational life to mid-2015 is expected (Ref. A spatial resolution of 10 m is provided in cross-track and 5 m (parallax direction) in along-track. 21) 22). Imaging Software Applications. However, the exact cause could not be properly identified. - On April 2, 2015, the SPOT-5 orbit was lowered by 2.5 km in order to reach an orbit at 820 km with a 5 day revisit cycle for the Take 5 mission and will remain on this orbit during 5 months. Need for Sentinel-2 data: At the end of 2016 when the Sentinel-2 constellation is complete, and for many years after, users will have access to high resolution series of images acquired every 5 days, anywhere over the Earth's land surfaces. The SPOT Basic software is a comprehensive but straightforward interface with features designed for microscopy imaging. So, when CNES offered to run short-term experiments with SPOT-4 before de-orbiting, CESBIO proposed the TAKE5 mission which consisted in moving SPOT-4 to a 5-day cycled orbit in order to simulate Sentinel-2 images. L'objectif principal de ce travail est de caractériser de façon synchronique les processus de dégradation du milieu forestier et de déforestation, dans différents modes de gestion de la forêt, par une analyse qualitative et quantitative du paysage au moyen d'une image multi spectrale SPOTS de 10 mètres, et deux images panchromatique SPOTS de 5 et 2.5 mètres de résolution. - 25 Years of SPOT Satellites: Since February 22, 1986, SPOT satellites have been keeping a watchful eye on the Earth. Now, 16 years later, it is time for SPOT-Vegetation to hand over the torch to its successor, the minisatellite PROBA- V(Vegetation) of ESA. The SPOT-5 local hour is slowly drifting since maneuvers for inclination correction are no more performed (hydrazine is saved for end of life operations). The main Sentinel-2 image features are: - High resolution: 10, 20 or 60 m, the spatial resolution depending on spectral bands, - Multispectral optical imagery: 13 spectral bands, from the visible to the short-wave infrared portion of the spectrum.

The TAKE5 experiment benefits from the earth observation SPOT-5 satellite after the end of its commercial mission and before its de-orbiting, using SPOT-5 as a simulator for time series optical images from ESA's Sentinel-2 constellation. B2: 0.61-0.68 In-flight measures confirmed that such ground measures are reliable. 28). The SPOT-5 satellite program continues the partnerships of France (CNES), Belgium (OSTC) and Sweden (SNSB) as established at the beginning of the SPOT program. 44), DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite). Suivi de l’environnement : Les images du capteur VEGETATION sont utilisées pour suivre l'évolution des écosystèmes continentaux. Brown bear and wolf also once roamed this area, but have disappeared through human influence and changes in the ecosystem over hundreds of years. 25). Three stored, compression factor: 2.6-3.0, Table 6: Overview of performance parameters of the SPOT family, Figure 21: Comparison of spacecraft bus sizes of the SPOT series, Improved attitude restitution for SPOT-5 (commissioning phase issues), An extra attitude restitution process has been developed in order to provide an accurate attitude for the imagery location model. - The yellow airfield in the northeast of the city is the Airport of Brussels , with the runways on the outside of the airfield. Thanks to this orbit, it will be possible to acquire data over selected sites every 5 days under constant angles for duration of around 5 months over the majority of the vegetation phase. - The objective of this end of life experiment, as the previous one, is to prepare the arrival of ESA's Sentinel-2 satellites (launches scheduled for June 2015 and 2016). The stricken Fukushima Dai-ichi nuclear power plant and its surroundings are still under surveillance and periodic reports will still be delivered over the next few months. HRS uses the same CCD line detector design as for the HRG instrument. Figure 5 : les images SPOT traitées : En haut : SPOT 1 hvr 1 KJ 37-248 14/05/1992. 20th Oct, 2015. Stereo and Tri-Stereo modes available on SPOT-6 and -7 and Pleiades are also available. Among the locations affected by the flooding are Antananarivo (the capital city), Manakara and Vangaindrano. The same location performance is required, regardless of HRG mirror viewing angles. Discover what's possible. - SPOT-4, with VGT-1 on board, was launched on March 24,1998. See description of instrument under SPOT-4 and under TOPEX/Poseidon. • April 9, 2015: On 2 April 2015, the SPOT-5 satellite was successfully maneuvered into a new orbit (orbit lowered by 2.5 km) as part of the mission's final phase. The Image Spot is ready to accept steel, black and white & color glass gobos, and even thicker Effects Glass gobos such as Image Glass and ColorWaves. Operational analysis studies conducted by CNES project a life expectancy at least to 2014 of the SPOT-5 mission. 13). 20). B2 (0.61-0.68 µm), 10 m The ACS (Attitude Control Subsystem) provides a pointing accuracy of 0.05º and an attitude restitution of 6 x 10-5 radians. SPOT-5 captured its first image of Port-au-Prince on Jan. 14 and several more over the surrounding parts of Haiti in subsequent days. Michel M. Verstraete. Moreover, the SPOT-5 system designed for its commercial mission had to be reconfigured to this new mission, involving different needs, within a short time. 26). Stopped tracking on August 2, 1993.
