This new way to design satellite constellations has interesting subsets such as “shape-preserving” constellations, “rock around orbits,” and “two-way orbits”. Thanks to number theory mathematical properties, the Flower Constellations have been generalized to the 2-D and 3-D Lattice versions and, finally, to the Necklace problem. The mathematics will be briefly described, and several relevant examples and animations of potential short-term and futuristic applications will be shown.</span></div><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px"><b>Speaker bio</b>: Daniele Mortari is full Professor of Aerospace Engineering at Texas A&M University, working on the field of attitude and position estimation, satellite constellation design, and sensor data processing. In addition, he has taught at the School of Aerospace Engineering of Rome’s University, and at Electronic Engineering of Perugia’s University. He received his dottore degree in Nuclear Engineering from University of Rome “La Sapienza,” in 1981. He is IEEE and AAS Fellow, AIAA Associate Fellow, Honorary Member of IEEE-AESS Space System Technical Panel, and former IEEE Distinguished Speaker. He has published about 280 papers and he has been widely recognized for his work, including receiving best paper Award from AAS/AIAA, two NASA’s Group Achievement Awards, 2003 Spacecraft Technology Center Award, the prestigious 2007 IEEE Judith A. Resnik Award and, recently, the 2016 AAS Dirk Brouwer Award. </span></div></div><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div>Kerri Cahoy<br>Assistant Professor of Aeronautics and Astronautics<br>Massachusetts Institute of Technology, 37-367<br>77 Massachusetts Ave.<br>Cambridge, MA 02139, USA<br>Cell phone: 650 814-8148<br>E-mail: <a href="mailto:kcahoy@mit.edu" target="_blank">kcahoy@mit.edu</a>, <a href="mailto:kerri.cahoy@gmail.com" target="_blank">kerri.cahoy@gmail.com</a><br></div></div></div>
