Book excerpt: 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.

Download or read book Inertial Navigation Systems with Geodetic Applications written by Christopher Jekeli and published by Walter de Gruyter. This book was released on 2012-10-25 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers all aspects of inertial navigation systems (INS), including the sensor technology and the estimation of instrument errors, as well as their integration with the Global Positioning System (GPS) for geodetic applications. Complete mathematical derivations are given. Both stabilized and strapdown mechanizations are treated in detail. Derived algorithms to process sensor data and a comprehensive explanation of the error dynamics provide not only an analytical understanding but also a practical implementation of the concepts. A self-contained description of GPS, with emphasis on kinematic applications, is one of the highlights in this book. The text is of interestto geodesists, including surveyors, mappers, and photogrammetrists; to engineers in aviation, navigation, guidance, transportation, and robotics; and to scientists involved in aerogeophysics and remote sensing.

Download or read book A New Concept in Strapdown Inertial Navigation written by John E. Bortz (Sr.) and published by . This book was released on 1970 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
