The subject matter disclosed herein is generally directed towards systems and methods for estimating vehicle attitude information using position data of stars and astronomical objects in the sky. Considerable advantages may be realized by equipping vehicle...

Spacecrafts are disclosed herein. The spacecraft can include a primary payload sensor, the primary payload sensor being aligned to capture images in a direction of a first axis, and at least one secondary imaging system for determining a position of the sp...

The invention relates to a test bench (1) for a stellar sensor, characterized in that it comprises: - a stellar sensor (2) comprising a protective baffle (3), - a collimator (7) mounted on one end of the protective baffle (3), - a screen (5) able to displa...

The device has a matrix display (10) or microdisplay for sequential display of color images, and control electronics (11), where the color images are provided at a specific display frequency. A generation unit is arranged for generation of color images tha...

The method involves detecting a star image cutout by star sensors (2,3,4) by a lens and a photosensitive matrix detector, where the star sensors are provided with the same or different visual fields and different viewing directions. An evaluation unit (5) ...

The star sensor (1) comprises an optical imaging system (2) with a lens (4) imaging a predetermined field of view (17,19) around an optical axis (7) on a sensor surface (6) of a detector (5) along an optical path (10,11). The lens has two partial lenses (8...

The method involves capturing a first set of star images (14) using a capturing head (6) of a star sensor (4) at frequency in a successive manner, where the sensor comprises another capturing head (5) for capturing a second set of star images (10) at anoth...
