Refinement of operable state recovery algorithms for “AIST” small satellites on the basis of telemetric information

Abstract


The article deals with the use of telemetric information, namely data on emergencies, failures and malfunctions occurring on AIST small satellites. These data are used for the refinement of standard algorithms of satellite operable state recovery. To this end, an analysis was made of the accumulated volume of telemetric information, consisting of two stages: searching for parameters exceeding the acceptable limits and establishing the causes of emergencies. A detailed study of the causes and consequences of emergencies made it possible to create two fault trees reflecting the ways of the propagation of failures in the small satellite onboard equipment. The use of fault trees and information on emergencies made it possible to refine the algorithms for the operable state recovery developed at the stage of designing AIST small satellites. Two examples of refined algorithms allowing the recovery of the operable state of small satellites after failure of on-board equipment are given in the article.
