Abstract:

The present state of knowledge of the charged particle radiation environment in synchronous orbit is described. The composition, intensity, energy spectrum and temporal variations of the radiation are listed. The data are based on measurements on board satellites in elliptical and in synchronous orbits, including the results from the electron telescope on board LES-4, whose apogee is in synchronous orbit. The radiation consists mainly of trapped electrons and low energy protons, but solar flare protons also make a significant contribution. The time-averaged data are given in a form useful for predicting the long-term radiation environment to which a satellite in synchronous orbit would be exposed.
