This report provides a detailed introduction to the problem of updating the rotational transformation of a strapped-down inertial guidance system. Analyses are specifically devoted to problems of updating the direction cosine transformation. Various digital computer algorithms for updating the direction cosines are displayed and discussed. Methods of performing error analyses on these algorithms are reviewed and results of IBM 7094 analyses are shown. The primary analytical results are representations of the truncation error resulting from the particular numerical forms studied. Author
