This report documents the result of several error analyses for PERSHING II inertial measurement unit gyrocompassing. The analyses have been beneficial in three ways. They offered an opportunity for a better understanding of the underlying mechanisms governing the dependence of gyrocompassing error on error sources. The analytic results provide a means for estimating gyrocompassing error from known error sources, and pave the way for the development of a technique for identifying source errors from a properly devised test. Three categories of error sources are discussed. Detailed analyses were made for two categories. Analysis for the third category was not done here.
