Envisat - Europe's newest scientific satellite / Gordon Petrie in Geoinformatics, vol 5 n° 2 (01/03/2002)

Given the satellite's huge size (10m in heigh) weight (8,5 tons) and cost ($2,3 billion) and the large battery of imagers and other sensors that have been mounted on it, this is probably the single most important Earth observation project that has ever been undertaken by ESA.. Indeed one can hardly contemplate the consequences for the Agency should there be a launch failure or a situation where the satellite cannot be operate fully. Not only have many of the current hopes of ESA been invested in Envisat, but so are the hopes of the large numbers of scientists who have signed up to use the data that will be generated by the satellite's imagers and other instruments. Indeed its importance within the scientific segment of the European space remote sensing community can hardly be over emphasized - especially for those involved in various different aspects concerning the monitoring of the environment on a global scale.

The Rapideye service: targeting the decisive gap in remote sensing / K. Van Der Lei in Geoinformatics, vol 5 n° 2 (01/03/2002)

Public [article]  inGeoinformatics > vol 5 n° 2 (01/03/2002) . - pp 22 - 23 Titre : The Rapideye service: targeting the decisive gap in remote sensing Type de document : Article/Communication Auteurs : K. Van Der Lei, Auteur Année de publication : 2002 Article en page(s) : pp 22 - 23 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Technologies spatiales [Termes IGN] capteur en peigne [Termes IGN] capteur multibande [Termes IGN] image à très haute résolution [Termes IGN] modèle numérique de surface [Termes IGN] précision géométrique (imagerie) [Termes IGN] radiométrie [Termes IGN] télédétection électromagnétique Résumé : (Auteur) In spite of recent optimistic growth prognoses, the commercial success of earth observation is hindered primarily by the inability of satellite operators to generate and consequently to deliver in time the requested products and services to the customer. This however, is vital for th establishment of any kind of service. a potential customer will only change his internal procedures and infrastucture if the avaibility of the alternative products is guaranteed. Consequently, a commercially operated system must aim primarily at offering guaranteed avaibility of information. A satisfactory avaibility of information on large areas of interest when using optical sensors can only be achieved by minimizing the time between the individual revisits and providing sufficient capacity. This understanding led to the definition of the RapidEye concept and the RapidEye imaging system.
