Stellar imaging systems require complex focal plane device structures to perform the basic functions of detection time - delay-and-integration (TDI) and scanning in field of large array formats. Charge coupled devices (CCDs) are the regular structure for scanning system focal planes which utilize principle TDI. A star sensor making use a linear and matrix CCD-TDI imaging processing system is presented.
