当年WorldView收购GeoEye后无限期推迟GeoEye-2的发射,原计划用于该任务的火箭改为发射NASA的火星任务MAVEN。巧合的是由于NASA火星任务Insight因技术原因推迟发射,用于该任务的火箭改用作VAFB的下次发射,载荷恰恰就是换了WV-4马甲的GeoEye-2。

这里提到的WV4是单色0.25,和DigitalGlobe的PPT都不一样。。。
是怎么回事
Westminster, Colorado-based DigitalGlobe now distributes commercial imagery with a resolution as sharp as 30 centimeters. Its WorldView-4 satellite, scheduled for launch later this year, is capable of producing 25-centimeter imagery. - See more at: http://spacenews.com/koreas-si-i ... thash.QA2Avp42.dpuf

Countdown to Launch: Lockheed Martin Makes Final Preparations for DigitalGlobe's WorldView-4 Earth Imaging Satellite

Date(s): 13-Jul-2016 5:13 PM



Sunnyvale, July 13, 2016 - Final preparations are underway at Lockheed Martin (NYSE: LMT) to ship DigitalGlobe's (NYSEGI) WorldView-4 earth imaging satellite to Vandenberg Air Force Base for a Sept. 15 launch.

The Lockheed Martin team is completing final satellite testing and checkout before shipment. Testing includes calculating the weight and center of gravity of WorldView-4, completing a health check of major systems, and testing out image collection and downlinking capability.

"The high resolution and high accuracy images taken by WorldView-4 will support DigitalGlobe's worldwide customer base," said Carl Marchetto, vice president and general manager of Lockheed Martin Commercial Space. "DigitalGlobe's smart imagery serves hundreds of thousands of end-users charged with the safety and security of nations, and enables the maps and geospatial applications relied on by billions of consumers."

"Only the DigitalGlobe constellation, with the addition of WorldView-4, offers the highest quality, and most comprehensive global coverage of our changing planet through 2030, so our customers can be confident they will have the information to make critical decisions," said Dr. Walter Scott, Founder and Chief Technology Officer, DigitalGlobe. "WorldView-4 will help us continue to transform the way we see the world, and advance our mission of keeping our planet and its people safe and secure."

Once launched, WorldView-4 will double DigitalGlobe's coverage of the world's highest resolution imagery and increase the rate at which it grows its 15-year library of time-lapse high-resolution imagery. WorldView-4 will orbit Earth every 90 minutes, traveling 17,000 miles per hour and capturing more 680,000 square kilometers of the Earth's surface daily (19.5 terabytes) the equivalent of the land area of Texas.

With an orbit approximately 400 miles from Earth, the satellite will be launched aboard a United Launch Alliance (ULA) Atlas V rocket provided by Lockheed Martin Commercial Launch Services.

DigitalGlobe’s technology has been instrumental in assisting in several disasters, including the disappearance of Malaysian Airlines flight 370 and the apprehension of a boat filled with slaves near Papua, New Guinea.  In recent months, the company was able to take photos of a massive wildfire in Fort McMurray, Alberta, Canada. The images provided firefighters will necessary information to make tactical decisions about how to best attack the blaze.
