Abstract:

The satellite launch industry is a multi billion-dollar international industry with over 100 commercial and military satellite launches conducted in 1999 alone. Rocket launches from both Cape Canaveral Air Force Station CCAFS and Vandenburg Air Force Base VAFB have been observed at operational infrasound stations monitored by the Prototype International Data Center PIDC. As more IMS infrasound stations are installed worldwide, we can expect to more frequently observe rocket launches. Rocket launches may serve as useful ground truth data andor Confidence Building Measures CBM to test and demonstrate IMS infrasound capabilities. Commercial and military launch facilities include Baykonyr in Kazakhstan, Plesetsk in Russia, Jinyu, Wuzhsi, Jiuquan, Xichang, and Taiyuan in China, Kourou in French Guinea, Alcantara in Brazil, Tanegashima in Japan, Vandenburg AFB and Cape Canaveral AFS in US, and the new Boeing ocean-going launch platform in the Pacific Ocean. Summer season Space Shuttle launches are seen at the experimental DLIAR 2550 km infrasound array in New Mexico and the more recently installed infrasound array, ISM 2780 km, in Canada. These long-range observations are strongly correlated with the geometry of stratospheric winds across North America. The 1-4 Hz signals arrive within 5 degrees of the nominal azimuth.
