EMS Technologies' Star Trackers Kept Genesis Spacecraft On Track During Three-Year Mission To Study Solar Wind From Sun


ATLANTA, Sept. 7, 2004 (PRIMEZONE) -- EMS Technologies, Inc. (Nasdaq:ELMG) today announced the successful use of its CALTRAC(R) Star Tracker system aboard the NASA Discovery mission, Genesis. The three-year mission concludes tomorrow when a capsule carrying samples of solar wind will be jettisoned from the spacecraft and "snagged" by a helicopter over the skies of the Utah Test and Training Range in central Utah. The Genesis capsule will enter Earth's atmosphere at 9:55 a.m. Mountain time. The collected samples of the solar wind will help scientists better understand the origins of our solar system.

Throughout Genesis' multi-million-kilometer-long trajectory, which took the spacecraft from Earth into a 30-month-long orbit located between the Earth and Sun, the spacecraft relied on EMS-designed and manufactured Star Trackers to guide it along its way.

Star Trackers are highly precise opto-electronic instruments that accurately establish a spacecraft's position. Images of the stars are used to "triangulate" the spacecraft position through the use of complex mathematical algorithms and advanced optics and electronics.

"The pair of EMS Star Trackers performed flawlessly throughout Genesis' three-year mission. Ours was the only star tracker commercially available for the Genesis mission that could meet its performance and speed requirements," noted Martin Lihou, program director, Optical Products Group in Ottawa, a part of EMS's Space & Technology/Montreal division.
