DigitalGlobe Anticipates Launch of WorldView-2 Satellite Late in 2008

Wednesday, March 12th, 2008


DigitalGlobe’s WorldView-2 is anticipated to launch in late 2008, pending finalization of customer contracts. WorldView-1 was launched in September 2007 and has been providing the highest resolution images ever captured by a commercial imaging system.

The WorldView-2 sensor will provide a high resolution Panchromatic band and eight (8) Multispectral bands; four (4) standard colors (red, green, blue, and near-infrared 1) and four (4) new bands (coastal, yellow, red edge, and near-infrared 2), full-color images for enhanced spectral analysis, mapping and monitoring applications, land-use planning, disaster relief, exploration, defense and intelligence, and visualization and simulation environments.

The WorldView-2 imaging payload is the second such system engineered and manufactured by ITT Space Systems Division for DigitalGlobe. Once deployed, operating at an altitude of 800 kilometers, the advanced imaging system to date will take pan-sharpened, multispectral images of the earth with better than 0.5-meter resolution from almost 500 miles above the Earth and will supply unprecedented detail and geospatial accuracy, further expanding the applications for satellite imagery in both commercial and government markets. Added spectral diversity will provide the ability to perform precise change detection and mapping.

The WorldView-2 telescope will have a 110-cm aperture and fly at a higher altitude of 770 km. It will provide the same panchromatic half-meter resolution imagery as WorldView I, in addition to 1.8-meter multispectral resolution imagery.

Worldview-2 will also have the ability for direct tasking, which will allow select customers around the world to load imaging profiles directly up to the spacecraft and execute delivery of the data directly down to their own ground stations.

WorldView-1 Update:

New Results for WorldView-1 at <2-meter Geospatial position accuracy with no ground control points!

PCI Geomatics has demonstrated by utilizing the PCI OrthoEngine module that the WorldView-1 satellite sensor can provide geospatial position accuracies of <2m without the use of GCP’s, saving you time and money. In fact, by adding 1 or more GCPs to a single scene or strip, expect accuracies of well under 1m RMSE.

What does this mean?

Obtain highly accurate results, even in areas where you don’t have much ground reference data

Create large mosaics without GCPs for anywhere in the world and still obtain high-accuracy reference images

Update your satellite base maps, including images in Google Earth or Yahoo Maps

Our unique Pan Sharpening techniques adds even more to the value, allowing WorldView-1 data to be merged with high-resolution color imagery (from QuickBird, IKONOS, SPOT5, Aerial Photography and more) for high resolution color scenes.

DigitalGlobe currently operates the QuickBird satellite, which can collect black-and-white, or panchromatic, images with 0.61-meter resolution at Nadir. The satellite, launched in October 2001, also collects multispectral images with 2.5 meter resolution. It is expected to operate until 2009. WorldView-1 high-capacity, panchromatic imaging system features half-meter resolution imagery. Operating at an altitude of 496 kilometers, WorldView-1 has an average revisit time of 1.7 days and is capable of collecting up to 750,000 square kilometers (290,000 square miles) per day of half-meter imagery. The satellite also is equipped with state-of-the-art geo-location accuracy of <2m without GCP’s while with one (1) or two (2) GCP’s the geospatial position accuracy is <1m and further exhibits stunning agility with rapid targeting and efficient in-track stereo collection.
