LASER RANGING TO THE SATELLITE GEOS A WITH THE MOUNT HALEAKALA OBSERVATORY LASER RANGING SYSTEM,
Abstract
The report describes a successful laser ranging experiment which was conducted on the retroreflector satellite GEOS A on 23 May 1969 at the Mount Haleakala Observatory, Maui, Hawaii. A total of 99 returns were obtained out of 113 laser firings during the sunlit portion of the satellite's pass. The returns were obtained from ranges of 2326 to 2937 km. The observed ranges are compared to predictions made by the Smithsonian Astrophysical Observatory, and it is found that the agreement is excellent. Acquisition and tracking techniques used during the ranging experiment are discussed. Photographs of the satellite and of an outgoing laser pulse (as seen on a television monitor) are presented. A brief description of the laser system and relevant Observatory support systems is also included along with some information on retroreflector satellites. (Author)
