The report describes five computer programs that are being used at the Naval Ordnance Laboratory for analyzing satellite magnetism. The programs contain numerical analysis algorithms for the spherical harmonic analysis of the magnetic field emanating from a satellite. The analysis is directed at determining the components of the magnetism which correspond to the dipole moment, quadrupole moment, etc. The first three programs were devised to analyze data from magnetic field measurements around the satellite. The fourth program was devised to generate simulated measurement data for a specified system of multipole magnets. The last program is a combination of the data generation and the data analysis programs. Sample problems are included in the discussion to illustrate the techniques of using the programs with a CDC 6400 Computer including the INTERCOM time-sharing system. A brief description is also included of data acquisition techniques and of principal subprograms.
