WorldView-1 Successfully Changes Orbit
European Space Imaging customers now benefit from more imaging access windows over Europe due to WorldView-1’s orbit change.
WorldView-1 now moves in an afternoon orbit meaning it now passes directly above Earth locations at around 1:30 pm local time. DigitalGlobe, the owner of the satellite, confirmed that the change from a morning orbit to an afternoon orbit took approximately 18 months to complete.
WorldView-1 uses a large telescope and advanced pointing technology to capture images of locations hundreds of miles to the east or west of its position, in multiple time zones. This change allows more imaging access windows during the day and will support DigitalGlobe’s three other high-accuracy, very high-resolution satellites in morning orbits, enabling customers to see the Earth anytime between 9 a.m. and 3 p.m. local time.

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.
