Fluid passivation procedure for artificial Earth satellites at the end of their mission includes discharge of reservoirs and electrical extinction

摘要

#CMT# #/CMT# The procedure, for use with a satellite containing an attitude monitoring and control system and at least one fluid reservoir, consists of stages that are programmed in advance and carried out automatically. They include one controlled and one uncontrolled fluid discharge stage that are ended automatically, and an electrical extinction stage. #CMT#USE : #/CMT# Passivation of artificial Earth satellites, especially communications satellites in geostationary orbits, at the end of their mission. #CMT#ADVANTAGE : #/CMT# The procedure enables satellites to be neutralised before placing in 'cemetery' orbit. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flow chart of the statges involved in the passivation procedure.
