Abstract:
Investigations were supported to analyze geophysical measurements with integrated applications of ephemerides physics, and mathematics of the ionosphere and near space. Projects undertaken included analytical and computational simulation of spacecraft interactions processes associated with charging, contamination, liquid venting, and critical ionization velocity; data based and analytical investigations of trapped particles, dosage, magnetic fields and instrumentation for the CRRES experiment; data based studies of auroral electron and ion precipitation including neural network techniques, ionospheric scintillation and OTH backscatter, and atmospheric density and orbital decay. Systems were developed and applied for calibration and processing of the CRRES and APEX magnetometers, and for generation of satellite attitude and ephemeris. Techniques employed for applying coordinate systems, depicting vehicle and astronomical circumstances, and interactively presenting data in conventional and color formats are also described....
