European Space Imaging announced today that on Tuesday 27 January 2015, after 13 years of excellent performance, QuickBird approached its end of mission smoothly and, according to the National Oceanic and Atmospheric Administration (NOAA) “re-entered the earths’ atmosphere at 01:59 UTC”.
DigitalGlobe confirms: “QuickBird de-orbited successfully. QuickBird was on orbit for more than 13 years, far exceeding its designed mission life. The satellite made over 70,000 trips around the Earth, contributing substantially to DigitalGlobe’s unmatched imagery catalog, and thus our understanding of our changing planet. Many thanks to our customers and partners for their support of a very successful mission. Imagery from QuickBird — as well as the rest of the DigitalGlobe constellation — can be still purchased from our imagery catalog.”
European Space Imaging will continue providing QuickBird imagery from their archive as well as taking new collection orders from the sibling satellites in the DigitalGlobe constellation.
Off Nadir Angle (ONA) plays a crucial role in the quality of optical satellite imagery. It influences its resolution and clarity, decides the visibility of features, and makes it easier or harder to identify objects. Moreover, ONA is used to create stereo imagery and 3D models of the Earth’s surface. Read on to learn more.
Sun glint occurs when sunlight reflects off water or another reflective surface at the satellite sensor, creating a bright glare in the image. That can make it impossible to extract useful information from satellite imagery. What do we do to minimise its impact?
Star forts are not only perfect examples of effective military engineering; they are also beautiful. Let’s join us on a fascinating journey through architecture and history – from space. All satellite images in this article were collected by WorldView-3, WorldView-2 or GeoEye-1 at 30–50 cm resolution.
