% The acquisition sequence for the ComStar satellite. Comstar is spinning in transfer orbit. When the demonstration starts it is at orbit normal. The acquisition sequence has the following phases: 1. Despin to the DST angular rate 2. DST with nutation damping 3. Pitch estimation 4. Pitch acquisition 5. Normal mode Phases 2-4 make use of the tach loop Since version 2. ------------------------------------------------------------------------- See also DSTCrit, PtchLoop, SSA, SpinREst, StatePrp, FGs, NPlot, ComStar, PitchEst, Q2Eul, Constant, Plot2D, TimeGUI, RK4 ------------------------------------------------------------------------- % ------------------------------------------------------------------------------- Copyright 1994-1998 Princeton Satellite Systems, Inc.
