ITT reached a key milestone with the successful completion of the Critical Design Review (CDR) for the imaging payload for WorldView-3, DigitalGlobe's high-resolution commercial Earth imaging satellite. WorldView-3 will combine the most productive high resolution commercial sensor subsystem available with a highly accurate and stable optical telescope unit.

"ITT has been recognized as the aerospace industry's leading imaging payload provider for more than 50 years," said Rob Mitrevski, vice president and general manager of ITT's Intelligence, Surveillance and Reconnaissance systems business area.

"Our design for the WorldView-3 imaging payload, which will provide improved imagery resolution, is now authenticated. We look forward to moving into the next phase of assembling, building and testing the WorldView-3 payload."

The recent CDR, conducted at ITT's facilities in Rochester, N.Y., is a key accomplishment for ITT and DigitalGlobe as the WorldView-3 payload program progresses toward delivery in mid-2013. The WorldView-3 imaging system incorporates enhancements to the optics and sensor sub-systems that will further expand the applications for satellite imagery in both commercial and government markets.

Depending on its final orbital altitude, the satellite's sensors will be able to acquire imagery between 25 and 41 cm of resolution. WorldView-3 will also include the panchromatic and unique 8-band multi-spectral imaging sensors that are hallmarks of the advanced WorldView-2 imaging system. The eight spectral sensors provide complete coverage of the visual spectrum, along with two near-infrared bands.

Together, the bands are designed to improve the segmentation and classification of land and aquatic features. Ultimately, they provide a more detailed view of the Earth, helping DigitalGlobe customers analyze imagery-based information in completely new ways.

"We are pleased with the progress we are making toward the launch of WorldView-3, which will add significant capacity to the most powerful constellation of sub-meter satellites in orbit," said Dr. Walter

S. Scott, Executive Vice President and Chief Technical Officer at DigitalGlobe. "WorldView-3 will help ensure our customers have access to the largest, most up-to-date image library of the world, and the very best foundation for making mission critical decisions."

ITT and DigitalGlobe's successful partnership spans more than a dozen years. WorldView-3 is the fourth high-resolution imaging system built by ITT for DigitalGlobe. The company built sensor subsystems for DigitalGlobe's QuickBird and WorldView-1 commercial imaging satellites, and the complete imaging payload for WorldView-2.

Ball Aerospace and Technologies Corp. has been named as the partner to build the spacecraft bus for the WorldView-3 imaging satellite.

El Segundo, Calif. (UPI) Mar 31, 2011
The first black box flight recorder designed to endure a re-entry from space survived a fiery return from low Earth orbit, its manufacturer said. Dubbed a re-entry breakup recorder, the heatproof device transmitted key data about its condition via satellite as it descended toward the Pacific Ocean between Chile and New Zealand Wednesday, NewScientist.com reported.
