Les images fournies par les satellites sont commercialisées par Astrium. SPOT-5 is the fifth satellite in the SPOT series of CNES (Space Agency of France), placed into orbit by an Ariane launcher. Les images SPOT sont commercialisées par la société Spot Image devenu filiale d'Astrium depuis son rachat par EADS Astrium en 2008. organization, Features It was initiated by the CNES (Centre national d'études spatiales – the French space agency) in the 1970s and was developed in association with the SSTC (Belgian scientific, technical and cultural services) and the Swedish National Space Board (SNSB). Un des grands atouts du système SPOT est sa capacité de dépointage de son instrument imageur principal de part et d'autre de la trace au sol du satellite, de +31,06° à -31,06°. SPOT-5 was successfully placed into orbit by an Ariane 4 from the Guiana Space Centre in Kourou during the night of 3 to 4 May 2002. Résolution des images par instrument HRV (haute résolution visible), il y a deux instruments par satellite (HRV1 et HRV2) : 10 mètres en panchromatique (canal couvrant le domaine, SPOT-4 effectue un cycle de 369 orbites en 26 jours sur une. Supermode: The term refers to an acquisition process, specific to the HRG instrument of SPOT-5, through which an image sampled at 2.5 m may be obtained from two 5 m resolution panchromatic images acquired simultaneously, keeping within the same borders as the two 5 m resolution images. Spot Image, filiale d'Astrium, porte l'investissement total et est propriétaire de l’ensemble du système (satellites et segments sols). 5 images: The new sampling concept is based on Shannon's theory of information which states that “the sampling frequency must be equal to or greater than twice the maximum signal frequency” to obtain clean images using interpolation.] Programmation réactive : 6 plans de programmation par jour pour chaque satellite. PA-2 (0.49-0.69 µm),5 m, B1 (50-0.59 µm) • The final issue deals with optimization of time delay between two HRG off-nadir image acquisitions. Stopped functioning March 31, 2015. In 1996, the SPOT-5 program was downsized (to one orbiting S/C) and redefined to improve the spatial resolution of the imagery below 5 m. As a result, an innovative image acquisition and processing scheme has been developed by CNES to obtain spatial resolutions of about 3 m from two 5 m images. The downlink is in X-band (QPSK modulation) at a data rate of 2 x 50 Mbit/s. Deorbiting of SPOT 2, in accordance with IADC (Inter-Agency Space Debris Coordination Committee), commenced in mid-July 2009 for a period of two weeks, with a final burn on 29 July 2009. Observation of the Earth and its Environment. • A fourth issue deals with an evaluation of HRG's steering mirror mechanism calibration. La réalisation de cette constellation de satellites est décidée en 2009 par EADS Astrium sur la base de l'analyse des besoins gouvernementaux pour ces données. Applications of the stereo imagery are seen in various fields such as map making and in the generation of DTMs (Digital Terrain Model) The panchromatic band (0.51-0.73 µm) of SPOT-1, -2, -3 is being reintroduced. SPOT-5. 27) 28), Figure 14: The star tracker on the space-facing side of the satellite between the two HRG instruments (image credit: CNES).  SPOT 5 also features an HRS imaging instrument operating in panchromatic mode. The construction was initiated by Spot Image of Toulouse (France), and EADS Astrium in 2008, and officially announced in mid 2009, by Astrium Services’ CEO Eric Beranger. utilisation de stations de réception mobiles pour alimenter le commandement sur le théâtre d’opération. In May 2002 the SPOT-5 satellite added its new capabilities to the SPOT family. In accordance with the International Charter, which is an agreement by multiple nations to provide access to remote sensing data during natural disasters, Spot Image routed image scenes captured by the SPOT ground receiving stations to the Spot Image headquarters in France. Segment spatial Jus u’en 2024, SPOT 6 et SPOT 7 fourniront des poduits d’une ésolution de 1,5 m couvrant des zones étendues. They offer a higher resolution of 2.5 to 5 meters in panchromatic mode and 10 meters in multispectral mode (20 metre on short wave infrared 1.58 – 1.75 µm). 18). Cette caractéristique est une conséquence des deux propriétés précédentes. 3439,70, 1998. Spot Image, a subsidiary of Astrium, funded the satellites alone and owned the system (satellites and ground segments) at time of launch. It implies that HRS location models have to include an accurate model of objective distortions. Quarante-trois stations terriennes sur les 5 continents. (Si) Launch: A launch of SPOT-5 on an Ariane-4 vehicle took place May 4, 2002. • In early 2008 some power problems of the power subsystem occurred. 9) Information provided by Alain Lapeyre of CNES, Chef de Service Exploitation des Satellites de Télédétection. 16), • The spacecraft and its instruments are operating nominally in 2009. SPOT-5 Satellite Sensor (2.5m/5m) - Decommissioned. Service Plans Tech Specs *SPOT devices require an active service subscription to properly perform. These users (cartographers, urban planners, environmental experts, foresters, agronomists,) have concluded that the supermode resolution is about 3 m (between 2.5 m and 3.5 m depending on applications and analyzed features). 1), The overall mission objectives are: 2) 3) 4). Les satellites de la première série sont réalisés par Matra (devenu EADS Astrium Satellites), avec Aérospatiale/Satellites (devenu depuis Thales Alenia Space). • The third item is to turn HRS stereo pairs parallax into a precise enough altitude estimate. However, the exact cause could not be properly identified. SWIR(1.58-1.7µm), 20 m, Detector line array (Si) All rights reserved. 17). - of Stockholm, Industrial SPOT products monitor your location, connecting to emergency responders while out of cellular range. • The SPOT-5 spacecraft and its payload are operating nominally in 2011. Ceci lui confère une très grande flexibilité d'acquisition, en ramenant notamment la répétitivité d'acquisition (fréquence temporelle ou fréquence de revisite) à 2-3 jours. Au début de 2015, l'IGN rend publique la carte du territoire métropolitain réalisée par le satellite SPOT-6 ; la résolution est de 1,5 mètre. DORIS, Eleusis harbour, Athens, 1 films), Spot Agriculture This new type of image, simulated with all its geometric and radiometric characteristics, has been compared by several users to other types of digital images at different ground resolutions. The SPOT 6 and SPOT 7 satellites were designed to continue SPOT-5 mission in obtaining wide-swath high-resolution imagery. Today, it is the world's leading civil Earth observation system. Telecommunications Get a complimentary consultation today. 12), - After the devastating Japanese earthquake of March 11, 2011, SPOT-5 was tasked by the International Charter on Space and Major Disasters to cover the coast that took the full force of the subsequent tsunami. As of mid-2004, preliminary results have already confirmed the high quality of the HRS instrument on board of Spot 5. The SPOT 5 "imaging" satellite, to be launched in April 2002, will provide digital elevation models (DEMs) of any location on Earth, allowing customers to create realistic 3D perspectives. The S/C is operational as of 2007. TMCU L'innovation de SPOT-5 est l’introduction du Super-Mode qui permet la création d’une image à 2,5 mètres de résolution à partir de deux images à 5 mètres acquises simultanément avec un demi-pixel de décalage. - and the first 3-D animation of Naples and Mount Vesuvius (MPEG Two HRG instruments are provided in the conventional SPOT-series double-observation configuration, each with a FOV of 4.13º and the same cross-track pointing capabilities of ±27 º as the HRVIR imager on SPOT-4.
