Abstract : A computing algorithm for the fixed-base self-alignment of a gimballess inertial navigation system is derived by the application of linear estimation theory. Simulation results indicate that the initial direction cosine matrix can be aligned in 20 seconds with not more than 10 arcseconds of error in azimuth or level. (Author)
