Research, analysis, development, and application of highly integrated systems of multi-phases of the physics of the upper atmosphere. Final report 15 January-15 July 1978
A variety of computer programs is used to fulfill the different requirements, generated by the various research programs, for satellite orbit data. Revisions to these programs are presented which enlarge the input/output capabilities, improve the accuracy of calculations, or extend the range of problems that can be addressed. Results are presented of investigations of the comparative accuracy of available programs for satellite orbit prediction and solar ephemeris calculation. Occasionally large-scale computer codes useful for geophysical analyses, but developed elsewhere, must be adapted to the needs of AFGL research programs and modified for use on the 6600 system. Cases in point are a code for predicting the proton and electron environments in the magnetosphere and another for transforming between geomagnetic and geographical coordinate systems. Modifications to these programs and procedures for their operational usage are presented. Atmospheric density modeling plays an important role in satellite orbit determination. Results are presented for efforts to incoporate new density models into orbit determination programs, evaluate the performance of different density models in orbit determination applications, and provide methods for model development by applying multiple regression to experimental data.
