It\nmay help you find out how the Kettering Group did their orbit determination.\nhttp://www.svengrahn.pp.se/trackind/trackin1.htm\n\nI had never heard of them, but they were certainly on the cutting edge at\nthe time. Makes me want to dust off my old Oscarlocator.\n73 de Doug ka8qcu\n\n\n\n----- Original Message -----\nFrom: \"Bob DeVarney W1ICW\" <[email protected]>\nTo: <[email protected]>\nSent: Friday, August 08, 2008 11:38\nSubject: [amsat-bb] satellite orbiatl prediction through obersvation\n\n\n> I. have been reading up on the history of the Kettering group and I am\n> particularly curious about one thing: how did they determine the orbit\n> of the satellite strictly from observation.
