Abstract: The present disclosure relates to a calibrated constellation simulator, a system and a method for calibrating and/or testing a star sensor assembled on a spacecraft. The calibrated constellation simulator comprises an optical device configured to project a defined star formation (IRF) of a star catalog onto a star sensor assembled on a spacecraft. Further, the calibrated constellation simulator comprises an alignment unit with a position and/or location reference (ARF) of the calibrated constellation simulator configured to detect a position and/or location of the calibrated constellation simulator in space, wherein the defined star formation (IRF) and the position and/or location reference (ARF) are in a first fixed calibrated rotation (QOSPS) with respect to one another. The calibrated constellation simulator improves the calibration of the star sensor as an independent calibration standard. The constellation simulator becomes a calibration standard.

Abstract: The present invention relates to a door system for a refrigeration device and a refrigeration device with such a door system.

Abstract: A dust shroud having a shroud body with a vacuum port and a tool connection, the shroud body including a top wall and at least one side wall extending downwardly from about a perimeter of the top wall that defines a dust receiving opening, the shroud body having a top wall opening and the tool connection including a flexible fitting with a flexible fitting base joined to the top wall and extending within the top wall opening, the flexible fitting including a plurality of flexible fingers with a base finger portion and an outer finger portion that extends away from top wall and is selectively with a mounting point of the hand held tool and the flexible fingers allowing selective controlled relative movement between the dust shroud and the hand held tool, the fingers having a finger spacing between adjacent flexible fingers and the outwardly extending flexible fingers having a finger length between the top wall and the distal finger end that is greater than 0.
