Strapdown inertial systems possess a potential advantage over more conventional inertial systems since they do not require a mechanical gimbal structure to maintain a stable coordinate reference. Instead, strapdown systems replace the gimbal structure by a direction cosine matrix which is contained in and updated by the system computer. To assess the performance of a strapdown system or to determine the computer requirements, a detailed study of the computational error introduced by the computer is necessary. This report is concerned with the techniques which may be employed to estimate the computational error and its effects on system performance. Although focused upon a particular problem of practical importance, many of the techniques have a wider applicability to aerospace in general.

In conventional strapdown inertial navigation systems, the coordinate transformation matrix differential equation is integrated in the computer of the system. This computation typically requires 30 to 60 percent of the time budget of the computer. A method is presented in this report for significantly reducing the digital computation burden through the use of hybrid computational techniques. Analog correction signals for the non-commutativity phenomenon are fed onto the gyro torque generators causing the gyros to integrate a vector differential equation in the rotation vector argument of the coordinate transformation matrix. The coordinate transformation matrix is then merely evaluated as a matrix function of the rotation vector argument. A 20 to 1 reduction in the digital computer time budget can thus be realized.
