"This was by far the best project management workshop I've attended!" "Excellent. This workshop met my expectations in every way. Thanks!" "Great! Glen did an awesome job. It was all valuable, especially Glen's real world experience." "A lot of information presented in a well organized and structured fashion." "I enjoyed the discussion of the different types of project teams structures." "Very useful information that was presented in a timely and organized manner." "I found the resource leveling most valuable. Good interaction with the audience." "Very useful. Especially the information on risk management, communication management, and change management." "Very good. Defining the team roles and responsibilities was valuable." "I could have used this years ago. Great use of visuals. Good reference manual. Great tool!" "I'd recommend this class to others. I plan to implement the techniques immediately, especially the skills on organizing and tracking." "Very well done. Glen is very knowledgeable of the subject matter." "Excellent information. I appreciated the speaker's experience and information base." "This was very helpful. I will be sending the rest of my project team to this course." "Most valuable were the three types of project specifications: implementation, non-implem...

The two body dynamics of an orbiting particle is usually governed by Newton's
laws of gravity and mechanics. Here the Kepler problem has been studied with the addition of the Lorentz force of magnetism. For micrometeoroids and small man made debris particles electromagnetic interactions may become important. The space environment is filled with charged particles, electrons and ions, that may be deposited on a 1 - 100 microns sized particle. The orbits of such charged particles have been modeled in earth orbit, with the dipole magnetic field superposed on the gravity field. An initial study of this problem has been conducted. Figures 1 illustrates a 600 second time frame of particles in a 300 kilometer altitude Earth orbit with a 5.7' inclination. The solid line is the pure Kepler problem. The dashed lines are the paths taken by various sized particles with a single positive charge of 1.6x10-'~ coulombs. The additional energy required to deflect these particles from a Kepler orbit comes from the deposition of charge at the initial stage in the calculation. From there the energy of the particle is conserved since both the gravitational and magnetic forces are conservative, i.e. $F d r = 0. The orbit of 1 micron sized particles has been computed and the results a r e shown in figures 2 through 5. The results of this numerical exercise in magneto-orbital dynamics a r e rather une... « previous next » |
