Fast forward to the past: NASA technologists test 'game-changing' data-processing technology
Date:11/27/2012

ds. "We'll take the hardware and see what it can do with our data and applications," Pellish explained.

One of the first applications the group plans to target with a version of the FFT integrated circuit is wavefront sensing and control, the computational technique for aligning multiple mirror segments, like those that are flying on the Webb telescope, so that they operate as a single mirror system.

In addition, Jeffrey Klenzing, who works with Goddard's Space Weather Laboratory, wants to evaluate the technology's use for on-board data processing, particularly for studies of the sun. "For a typical sounding rocket application, we send all data down and perform fast Fourier transforms on the ground. However, for satellite missions, this is not feasible given limited telemetry," Klenzing said. "A chip for performing rapid, reliable FFTs would be very useful for such heliophysics missions particularly with the push toward smaller, low-power satellites such as CubeSats and nanosats."

Pellish also believes autonomous rendezvous and docking and other applications requiring precise locational information would benefit from the analog-based technology. "We're trying to create a new market at NASA for analog processing. I believe it will give us a competitive edge. If we can push this, it could revolutionize how we do onboard data processing."
