A satellite positioned\nthere would require constant positions corrections: complex satellite. L4\nand L5 are stable.\n\n- When n L points are populated and you want to populate another L point,\nyou have to solve an (n+2)-body problem. This becomes extremely complex.\n \n- L4 and L5 are about the same distance from Earth as the moon: EME type\ncomplications for communications.\n\n\nhttp://www.physics.montana.edu/faculty/cornish/lagrange.pdf\n\nhttp://www.physics.montana.edu/faculty/cornish/lagrange.html\n\nhttp://en.wikipedia.org/wiki/Lagrangian_point\n\nhttp://www.esa.int/esaSC/SEMM17XJD1E_index_0.html\n\n\n\n-----Original Message-----\nFrom: [email protected] [mailto:[email protected]] On\nBehalf Of [email protected]\nSent: January 12, 2007 08:07\nTo: [email protected]\nSubject: [amsat-bb] Lanrangian points\n\nHello Amsat'ers\nIs it possible or practical to have a communications satellite at the L1 or\nL2 points.\n73 Bob W7LRD\nSeattle\n_______________________________________________\nSent via [email protected].
