A star tracker is an optical device that measures the positions of stars using photocells or a camera. [1] As the positions of many stars have been measured by astronomers to a high degree of accuracy, a star tracker on a satellite or spacecraft may be used to determine the orientation (or attitude) of the spacecraft with respect to the stars ...

Video astronomy (aka - Camera Assisted Astronomy, aka electronically-assisted astronomy or "EAA" [1]) is a branch of astronomy for near real-time observing of relatively faint astronomical objects using very sensitive CCD or CMOS cameras.
Staring arrays are distinct from scanning array and TDI imagers in that they image the desired field of view without scanning. Scanning arrays are constructed from linear arrays (or very narrow 2-D arrays) that are rastered across the desired field of view using a rotating or oscillating mirror to construct a 2-D image over time.
In the past, plate solving was done manually by accurately measuring photographic glass plates taken with an astrograph (astrographic camera) [2] [3] Currently, astrometric solving is exclusively done by software programs. The program extracts the star x,y positions from the celestial image, groups them in three-star triangles or four-star quads.
The Raspberry Pi Foundation was created as a private company limited by guarantee in 2008, [8] and was registered as a charity in 2009 [9] by people at the University of Cambridge Computer Laboratory who had noticed a decline in the number and skills of young people applying for computer science courses.
The Virtual Operation System (VOS) provides a portable interface for the application tasks. It is modeled after the Unix system functions, but with an API for the IRAF specific Subset Preprocessor language (SPP). The Host System Interface (HSI) is the kernel providing an interface between the host system and the functions of the VOS. It also ...
Whole sky camera also popularly known as an all-sky camera in the astronomical field is used for meteor, fireball, and spacecraft reentry recording and identification. While mostly identical to the meteorological application, the system for astronomical use tends to have a more sensitive night camera and much longer exposure due to the night ...
