A star mapper using linear 2048 element CCD array is being developed for providing high accuracy post-facto attitude information for the India Remote Sensing Satellite (IRS-1A) scheduled to be launched by the end of 1986. The sensor employs the orbital motion of the sun-synchronous satellite to map the sky at the orbital rate and generates co-ordinate information of the stars using an 1802 based processor system. A four element 75mm aperature catadioptric system is used for sensing stars upto fifth magnitude. The CCD is cooled by means of thermoelectric cooler to -20 C. Details of the sensor design are presented in this paper.
