MINIATURISED APS STR: A CHALLENGING FIRST DELIVERY

摘要

Galileo Avionica realized the first Flight Model of arnhighly compact and light APS based star tracker,rnproviding accuracy comparable with those achievablernwith CCD star trackers. This state of the art AA-STRrnstar sensor really does herald the beginning of a new agernfor Star Tracker sensors that will come to see themrndominate the satellite AOCSs of the future.rnSince May 2000 Galileo Avionica is deeply involved inrnthe introduction of Active Pixel Sensor Focal Planes inrnattitude sensors and navigation and vision cameras. Inrnparticular, contracts have been acquired for therndevelopment/qualification of a miniaturised sun sensorrn(FMs were already delivered for GOCE), for the BepirnColombo Star Tracker and for Vision Based NavigationrnCamera (for the Navigation for Planetary Approach andrnLanding system).rnIn addition the pre-development of the APS based starrntracker for AlphaBus is currently under completion andrnthe refurbishment activities on the Bepi Colombo STRrnPrototype for its in-flight test on board Proba-2 arernrunning.
