IRAS in-orbit checkout
Abstract
The in-orbit checkout (IOC) procedures which permitted astronomical observations with the IRAS to begin on schedule despite postlaunch complications are reviewed. The IRAS attitude-control system and on-board computers are characterized, and the general and attitude-control-related parts of the 14-day IOC program are described. The fine-sun-sensor spiking problem observed during the first few days of the IRAS mission (in January, 1983) and the corrections introduced from the ground into the attitude-control program are discussed in detail and illustrated graphically.
