Radiation Dose in Satellites at 1111 Kilometers with an Inclination of 63 Deg.
Abstract
A computer program was written to provide a convenient means of calculating the radiation dose received by a satellite in a specified orbit over a given time period. In this case, the orbit is circular at 1111 km altitude, 63 deg inclination. The input data required are tables of annualized orbit-integrated radiation dose vs. shielding thickness (or density) which were obtained from a separate calculation. These were prepared by the National Space Science Data Center, covering the time period from 1981 to 1989, from space environment models AP-8, AE-5, AE-6, AEI-7, and SOLPRO. The radiation dose was calculated using an infinite slab shielding geometry for trapped electrons, bremsstrahlung, trapped protons, and solar protons. A plotting routine for graphing 26 shield thicknesses up to 700 mils of aluminum is provided. Instructions for program execution and data deck setup, samples of the data tables and graphs, and a program listing are included.
