QuVIS servers were chosen for some of NASA's "quick look" and tracker applications. The selection came as a result of NASA's decision to upgrade the quality and transportability of imagery available for detection and assessment of any launch anomalies related to the space shuttle program.

NASA evaluated a wide range of compressed and uncompressed systems to find the solution that best addressed their demand for image quality.

"Our requirement was maintaining image integrity in limited bandwidth," Rodney Grubbs, Chairman, NASA DTV Working Group, said. "Our image analysts found no significant difference between uncompressed files and files using wavelet compression with a QuVIS recorder."

The QuVIS servers, including the QuVIS Acuity, were deployed at several NASA facilities including: Goddard Space Flight Center, Maryland; Marshall Space Center, Alabama; Kennedy Space Center, Florida; and Johnson Space Center, Texas. These units will be used to track and analyze launches of NASA vehicles.

QuVIS servers are installed in two WB-57 jets based at the Johnson Space Center. Customized for NASA, these units utilize solid-state hard drives that withstand the rigors of flight. During a shuttle launch, the WB-57 aircraft will fly at altitudes of 60,000 feet while using HD cameras to capture launch tracking imagery directly to the servers.

In a similar land-based version of this project, servers and high definition cameras were installed to shoot video of NASA spacecraft, including the Space Shuttle fleet, before, during and after the launches. Special enclosures on the launch pad hold HD cameras and are connected to QuVIS servers capturing images of the shuttle during takeoff.

Additional tracking cameras located downrange from the launch are linked to QuVIS servers to capture images of the vehicles in flight. The data from these servers is then electronically transferred from the field to image analysis centers in Alabama, Florida and Texas.

Secure electronic transfer reduces the time necessary to provide this "quick look" imagery from the air and land-based servers to the image analysis labs.

QuVIS utilizes "Quality Priority Encoding" (QPE) to guarantee image quality - allowing users to capture exactly what the camera provides, while storing it in a fraction of the space. This solution is replacing older tape-based technology.

"We're excited by the opportunity to work with NASA," said Kenbe Goertzen, CEO of QuVIS, Inc. "We hope that this will be the first of many applications for our technology within the space program."
