Book Description
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.

Book Description
Inertial navigation is widely used for the guidance of aircraft, missiles ships and land vehicles, as well as in a number of novel applications such as surveying underground pipelines in drilling operations. This book discusses the physical principles of inertial navigation, the associated growth of errors and their compensation. It draws current technological developments, provides an indication of potential future trends and covers a broad range of applications. New chapters on MEMS (microelectromechanical systems) technology and inertial system applications are included.
