Unformatted text preview: ASE 366K Problem Set #1 Posting Date : September 2, 2009 Due Date : September 10, 2009 Turn in homework at the beginning of class. If you have any doubts about your ability to make it to class on time, you may turn in your problem solutions by sliding them under my office door (WRW 411C) the day before they are due. Be prepared to answer any of these problems—or similar problems—on an upcoming exam. You may discuss your solutions with classmates, but do not swap work. Only one of the homework problems, chosen at random, (or one part of one problem, if that part is sufficiently involved) will be graded thoroughly. The grade given to the homework set will be based primarily on this problem. The other problems will be graded on a credit/no-credit basis depending on whether a solution was attempted. (1) The Iridium satellite constellation is a set of roughly 66 communication satellites in low-earth orbit. Each satellite is equipped with three main mission antennas—large phased-array antennas that transmit at L-band. These antennas also happen to be highly reflective. Under the right circumstances, an antenna can reflect sunlight down to an observer on Earth. These reflections are known as “Iridium flares.” Go to the Heavens Above web site (http://www.heavens-above.com). Enter your coordinates (for reference the WRW building is located at 30.2875 deg N, 97.73606 deg W) and time offset from GMT. Note that you do not have to register to enter your observing site. Print out a list of the flare events that will occur for your location/time over the next 7 days.over the next 7 days....
