8WorldView-3: Have you seen this GIF?

By DigitalGlobe | Published:

In a view only DigitalGlobe could manage with multiple satellites in our constellation, WorldView-1 caught this sequence of images of the WorldView-3 Atlas V launch vehicle as it launched from Vandenberg AFB in California last Wednesday. The rocket was really moving; by the time of the last frame, WorldView-3 was traveling at just over 1,000 mph at an altitude of 49,000 feet. WorldView-1 shot these while moving at 17,000 mph at an altitude of 307 miles above the ground, at a distance of between 500 and 750 miles from the rocket.

As we sent WorldView-3 up to begin capturing more images of the earth, we’re proud that WorldView-1 was able to witness the “birth” of its newest sibling.

Last Friday, we were thrilled to have Time.com be the first to share the news of DigitalGlobe’s sequence of images turned to a GIF, thanks Time!

In addition to WorldView-1, which enabled us to capture a view of WorldView-3’s Atlas V launch vehicle from above as it climbed up through the atmosphere, we also had WorldView-2 looking at the launch from a greater distance (about 2000 miles) and a more oblique angle. We wanted to share this image that show the launch of WorldView-3 from the side, as it climbed up through 84,000 feet, where it was traveling at almost 1700 mph.

WorldView-3: Preparing for Launch!

By DigitalGlobe | Published:

With less than 24 hours left prior to the slated take-off time, we are eagerly anticipating the launch of WorldView-3, DigitalGlobe’s most sophisticated high resolution imaging satellite ever put into orbit!

The scheduled launch is for August 13, 2014 from Vandenberg Air Force Base, Calif. at 11:29 a.m. PDT (2:30 p.m. EDT, 6:30 p.m. UTC.)

In addition to launch activities in California., Lockheed Martin Corp., Ball Aerospace Technologies Corp., Exelis,  United Launch Alliance and DigitalGlobe, Inc. will be participating in a community watch event in partnership with the Denver Museum of Nature and Science (DMNS) in Denver, Colorado. This event is free and open to the public with Museum admission.

You can also join us by watching via the ground-to-orbit webcast provided by United Launch Alliance. Tune in about 20 minutes early and you’ll be able to hear the countdown!

WorldView-3: An evolution of the satellites coming before it

By DigitalGlobe | Published:

By Craig Oswald Exelis Geospatial Systems, Commercial Imaging Manager
When WorldView-3 begins downlinking its first images in a few months, DigitalGlobe customers will have access to the highest resolution imagery commercially available to better support the growing needs of a variety of industries including agriculture, oil and gas, and mining. From seeing the visible to the invisible, WorldView-3 will offer dramatically more information in every image collected. WorldView-3 is an evolution from the commercial imaging satellites that came before it and the next iteration of remarkable technology.

A powerful combination of capabilities, the integrated, super-spectral payload consisting of a telescope, sensor and shortwave infrared system is the latest payload provided by Exelis to support DigitalGlobe. Exelis has provided the remote sensing payloads for all of DigitalGlobe’s satellite constellation including IKONOS, QuickBird, WorldView-1, GeoEye-1, WorldView-2 and now WorldView-3 follows in the path of these systems with new and enhanced features.

Exelis helped create the commercial remote-sensing market by designing and building the imaging system for IKONOS, the world’s first commercial high-resolution satellite, launched in 1999 and still operating today. Exelis also built the payload for GeoEye-1, the world’s first space-borne imaging system with better than one-half meter resolution.

In 2007, WorldView-1 launched as the first of DigitalGlobe’s next-generation satellites and was considered the most agile imaging satellite ever flown commercially. It can collect more than 1.5 million square kilometers per day of half-meter imagery. In October 2009, WorldView-2 launched and became the first commercial imaging satellite to carry a high resolution 8-band multispectral sensor. It provides the ability to image all of the world’s urban areas every two weeks. It can also image all arable land and permanent crops every month. WorldView-2 opened a number of applications to include mapping wetlands, algae blooms vegetation and urban sprawl, among many. Five years later, WorldView-3 will have double the number of spectral bands, opening even greater capability.

WorldView-3 will be able to provide 31 centimeter resolution from 617 kilometers away. For perspective, that is the same as the distance between Southern California’s Hollywood sign and the Golden Gate Bridge in San Francisco. If the imagery were located at the Hollywood sign, users would be able to count all of the people on the Golden Gate Bridge.

Because the characteristics of various materials reflect light differently, the use of more spectral bands is the key to distinguishing between them and why WorldView-3 will provide panchromatic and 16 spectral bands. This “super-spectral” capability means we’ll be able to see the difference between a red car and a blue car. Very near-infrared enables distinguishing between a Maple tree and a Pine tree. While short-wave infrared provides the ability to “see” through clouds and haze, allowing users to identify houses near a forest fire through the smoke, for example. This is a capability that will be very useful in applications for mapping, land classifications, disaster preparedness and response, soil and vegetation analysis, geology uses, environmental monitoring and coastal applications.

The satellites in DigitalGlobe’s constellation have steadily evolved with increasing resolution, spectral bands, on-board storage, agility, geolocation accuracy, and downlink rates. Exelis has developed scalable, modular sensor architectures with smaller pixels, faster line rates and better sensitivity enabling improved ground sample distance. All of the improvements made from generation I and II remote sensing satellites have enabled the collection of better data to support decision making across industries.
