Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather, long-term climate change, natural disasters.
A satellite minidish. This is a list of the free-to-air channels that are currently available via satellite from SES Astra satellites (Astra 2E/2F/2G) at orbital position 28.2 °E, serving Ireland and the United Kingdom. Sky and Freesat use these satellites to deliver their channels. If one was to change providers between Sky and Freesat, one ...
Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and ...
WorldView-3 ( WV 3) is a commercial Earth observation satellite owned by DigitalGlobe. It was launched on 13 August 2014 to become DigitalGlobe's sixth satellite in orbit, joining Ikonos which was launched in 1999, QuickBird in 2001, WorldView-1 in 2007, GeoEye-1 in 2008, and WorldView-2 in 2009. WorldView-3 provides commercially available ...
The satellites orbit in a circular low Earth orbit at about 500 km (310 mi) altitude [315] in a high-inclination orbit for a planned six to twelve-month duration. The satellites communicate with three testing ground stations in Washington State and California for short-term experiments of less than ten minutes duration, roughly daily. [310] [316]
The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.
By 1999, following the launch of several more satellites (at 19.2°E by SES), the number of channels had increased to around 60 and BSkyB launched the first subscription-based digital television platform in the UK, offering a range of 300 channels broadcast from the SES Astra satellites at 28.2°E under the brand name Sky Digital. BSkyB's ...
It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. [ 1 ] The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images.
