CHARLOTTE, N.C., March 9 – The Japan Aerospace Exploration Agency (JAXA) has released the first images from the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) payload on their Advanced Land Observing Satellite (ALOS).
The imagery was released less than one month after the ALOS launch, much quicker than is typical for sophisticated imaging systems. The images clearly show objects as small as cars and the stereo imaging, a unique capability for an Earth observation satellite, allows generation of three-dimensional “fly-by” movies http://www.jaxa.jp/press/2006/02/20060215_daichi_e.html.
Goodrich Corporation’s (NYSE:GR) Electro-Optical Systems team developed the advanced high precision optical systems in the three PRISM payload telescopes that provide the three-dimensional images. Each telescope has a unique optical configuration allowing it to capture large areas on the ground. The Goodrich-produced mirrors for each of these lightweight systems are 0.6- meters in maximum dimension and are polished to a surface precision better than 10 billionths of a meter. In addition to the three flight systems launched on the ALOS satellite, Goodrich supplied another complete set of systems for an Engineering Model and provided on-site support in Japan for integration of the PRISM payload.
Goodrich also provided the attitude control hardware that supports precision pointing of the ALOS spacecraft to specific regions of the earth. These items incorporate Goodrich proprietary fine balancing processes which dramatically reduce the disturbances imparted to the satellite and allow proper operation of this highly-sensitive satellite.
The ALOS system will aid scientists in their search for natural resources, help cartographers around the world create more precise maps, and provide support for disaster response. Further details of the PRISM Instrument and ALOS mission can be found at http://www.eorc.jaxa.jp/ALOS/.
