SSP 30425B, SPACE STATION PROGRAM NATURAL ENVIRONMENT DEFINITION FOR DESIGN - INTERNATIONAL SPACE STATION ALPHA (08 FEB 1994)

SSP 30425B, SPACE STATION PROGRAM NATURAL ENVIRONMENT DEFINITION FOR DESIGN - INTERNATIONAL SPACE STATION ALPHA (08 FEB 1994)., The purpose of this document is to define the natural environment for design of the Space Station Program Elements (SSPEs). The natural environment includes neutral atmosphere, plasma, charged particle radiation, Electromagnetic Radiation (EMR), meteoroids, space debris, magnetic field, physical constants, and gravitational field. Communications and other unmanned satellites operate in Geosynchronous Earth Orbit (GEO). Therefore, some data are given for GEO, but the emphasis is on altitudes from 200 kilometers to 1000 kilometers (LEO) which is inclusive of the orbital design range of the SSPEs. This document does not cover the induced environment or other effects resulting from the presence of the SSPEs. Man–made factors are included as part of the ambient natural environment; i.e., orbital debris and Radio Frequency (RF) noise generated on Earth. They are included because they are not caused by the presence of the SSPEs but form part of the ambient environment that the SSPEs experience. It is very important to take induced environments into account because they can be quite different from the unperturbed ambient natural environment. This document does not provide techniques or engineering solutions to permit operation in the natural environment described herein.
