Eos Systems Inc. Awarded Software Development Contract by NASA

Vancouver, BC - November 28, 2001 - Eos Systems, the developer of PhotoModeler software and leading photogrammetric technology, has been awarded a software customization contract by NASA. The contract work will enhance PhotoModeler to meet NASA's need for a software program that can produce measurements and models from video image sequences. Video-sequence based measurements are crucial to the testing process used by NASA in the Gossamer Spacecraft Initiative, which develops enabling technologies for very large, ultra-lightweight space structures.

The Structural Dynamics Branch at the NASA Langley Research Center will use the software to perform structural tests on ultra-thin space structures such as large antennas and observatories, solar sails, inflatable solar arrays and concentrators, and inflatable habitats. In order to study the viability of these structures, NASA needs to measure: 1) deployment dynamics, 2) deployed static shape, and 3) deployed vibration characteristics. Non-contact photogrammetry is the only appropriate way to do the measurements.

"We are proud to be a part of this important NASA project", says Alan Walford, President of Eos Systems. "NASA is a long time user of PhotoModeler software, having performed extensive tests and advanced work with PhotoModeler. The fact that PhotoModeler software has met NASA's high standards proves the strength and quality of our technology. We are pleased to implement this customization of PhotoModeler to help NASA meet their goals."

NASA has been using PhotoModeler and images from a digital camera to perform photogrammetric measurements of an inflatable space antenna. The new video sequence capabilities will enable NASA to perform measurements at multiple intervals as antennas and other structures unfold, allowing them to study shape and vibration characteristics.
