Charged C a ged depos deposition t o be behind d known o sshielding ed g in a highly inclined orbit by J. F. Fennell1, J. L. Roeder1, J. B. Blake1, J. Mazur2, T. Guild2, and P. O’Brien2 (1) The Aerospace Corporation Corporation, Los Angles Angles, CA (2) The Aerospace Corporation, Chantilly, VA Physical Sciences Laboratory 11TH Spacecraft Charging Technology Conference Albuquerque, NM 20-24 Sept. 2010 joseph.fennell@aero.org 310 336 7075 © The Aerospace Corporation 2010 Organization of Talk • Introduction I t d ti • Identify spatial regions covered and measurements used • Show extended history of radiation belt variations in HEO and ICO orbits • Relate radiation belt flux variations to simple capacitive model of internal charging time scales • Summarize results 2 Introduction • Internal charging and resultant discharges (IESD) are of concern for all satellites because it causes upsets and can cause circuit failures and malfunctions – Especially in those satellites that spend significant time in the outer radiation belt and those with limited shielding • Several authors have attempted to provide guidance to the satellite industry as to what shielding requirements are that can protect satellite systems from IESD • Modeling tools have become available for estimating internal charging rates given p spectrum p an input – Some have been published (Dictat) and some will be presented at this meeting (see presentation by Lemon and poster by Mulligan) • Recently, Bodeau published an article (2009 AIAA paper) that examined energetic electron l t climatology li t l ffrom th the perspective ti off estimating ti ti iinternal t l charging h i risk i k iin GEO orbit (He has a poster here on the same subject) – He found that simple rules of thumb often used by industry about charging rates, such as p g charging g g rates <100 fC for ≤10 hours, were not appropriate pp p for GEO orbit when keeping highly resistive materials were involved • Using a similar process, we examine the energetic electron climatology for a HEO and a MEO orbit where we have several years of electron fluxes behind different shielding levels
