SHORT RANGE POSE AND POSITION DETERMINATION OF SPACECRAFT USING A μ-ADVANCED STELLAR COMPASS

摘要

Fast and reliable pose and position of a Targetrnspacecraft can be obtained through the use of arnminimum of four clearly visible feature points on thernTarget spacecraft. This paper describes how a visionrnbased sensor (VBS), using this principle, is realized asrnan augmented mode of the already space provenrnnavigation instrument, the μ-Advanced StellarrnCompass. The system reveals high speed, reliability,rnaccuracy and availability, from the pose and positioningrndetermination process.rnPerforming rendezvous and docking maneuversrnbetween two formation flying satellites, requires fastrnand reliable relative pose and position information.rnClosed loop operation of the VBS instrument, as usedrnonboard the PRISMA mission, enables pose andrnposition determination in between the two spacecrafts.
