Question: The color image displayed on the left is a new kind of RGB composite image, can you guess how it was made ? Hints: the blue bright pixels correspond to water, but water is not bright usually… except if it is obtained in specular condition, when the water surface mirrors the sun towards the […]
A single VENµS acquisition is sufficient to estimate the terrain elevation of a scene thanks to the so-called « native stereo » technique. One of the main missions of VENµS, the Franco-Israeli satellite launched in August 2017, is to carry out acquisitions over more than a hundred scientific sites around the world. Its resolution at 5.3 m […]
=> A new attitude estimation method has been developed for the VENµS satellite, based solely on image content. The registration quality can thus be improved by a factor of 10, paving the way for new applications. Since its launch in August 2018, the Franco-Israeli Venµs pushbroom satellite has been affected by attitude restitution noise that […]
Une nouvelle méthode d’estimation d’attitude a été développée pour le satellite VENµS, basée uniquement sur le contenu des images. La qualité de superposition peut ainsi être améliorée d’un facteur 10, ouvrant la voie à de nouvelles applications. Depuis son lancement en aout 2018, le satellite pushbroom franco–israélien Venµs est affecté par un bruit de restitution […]
Une seule acquisition VENµS suffit pour estimer le relief de la scène grâce à la technique dite de « stéréo native ». Une des missions principales de VENµS, le satellite franco-israélien lancé en août 2017, est d’acquérir régulièrement des images sur plus d’une centaine de sites scientifiques répartis dans le monde. Sa résolution à 5,3 m par […]
Venµs is a research satellite, and a rather agile one (at least for a microsatellite). It enables us to make experiments useful for users like us who like to study physics of optical measurements (which is an allowed perversion, as fas as I know). We have started last year to acquire multi-angular observation, under 3 […]
1/ New 5m Level 2 products The Venus L2 production has been moved to a different processing center. From January 2020, the VENµS L2 production is only performed by the MUSCATE processing center, instead of the VIP (VENµS Image Processing) center, with MAJA processor also used for Sentinel-2. The aim is to improve the integration […]
About one year ago, we had submitted a call for ideas for the use of VENµS imager after the end of its nominal phase. CNES also organised a brain storming meeting, which came up with a few ideas, and then our proposals were discussed with our israeli partners. Here is what was agreed between CNES […]
There will be no VENµS image acquisition from January 7th to February 8th 2020. This period (called IHET month) is devoted to the test of the Israeli electric thruster (IHET)developed by Rafael Ltd, which is one of the missions of the satellite. (in order to be kept informed of such events and other news, please […]
