A gyroscope-free inertial navigation system uses only accelerometers to compute navigation trajectories. It is a low-cost navigation system, but its output error diverges at a rate that is an order faster than that of a conventional gyroscope-based system. So integration with an external reference system, such as the Global Positioning System, is necessary for long-term navigation applications. The linear and nonlinear error models of a gyroscope-free INS are derived and are used as Kalman filter equations to estimate the errors in the gyroscope-free INS data. The effects of gyroscope-free inertial measurement unit errors are also analyzed.

Global Positioning Systems, Inertial Navigation, and Integration

An inertial navigation system INS is a navigation device that uses a computer , motion sensors accelerometers and rotation sensors gyroscopes to continuously calculate by dead reckoning the position, the orientation, and the velocity direction and speed of movement of a moving object without the need for external references. INSs are used on mobile robots [2] [3] and on vehicles such as ships , aircraft , submarines , guided missiles , and spacecraft. Older INS systems generally used an inertial platform as their mounting point to the vehicle and the terms are sometimes considered synonymous. Inertial navigation is a self-contained navigation technique in which measurements provided by accelerometers and gyroscopes are used to track the position and orientation of an object relative to a known starting point, orientation and velocity. Inertial measurement units IMUs typically contain three orthogonal rate-gyroscopes and three orthogonal accelerometers, measuring angular velocity and linear acceleration respectively. By processing signals from these devices it is possible to track the position and orientation of a device.

Global Positioning Systems, Inertial Navigation, and Integration, Second Edition

It serves as an excellent reference for working engineers as well as textbook for beginners and students new to the area. The authors explain the derivations in great detail. The intermediate steps are thoroughly explained so that a beginner can easily follow the material. It provides detailed illustrations for an easy comprehension. The book also demonstrates real field experiments and in-vehicle road test results with professional discussions and analysis. Those schemes include loosely vs tightly coupled, open loop vs closed loop, and many more.

Written by recognized authorities in the field, this second edition of a landmark work provides engineers, computer scientists, and others with a working familiarity with the theory and contemporary applications of Global Navigation Satellite Systems GNSS , Inertial Navigational Systems INS , and Kalman filters. Throughout, the focus is on solving real-world problems, with an emphasis on the effective use of state-of-the-art integration techniques for those systems, especially the application of Kalman filtering. To that end, the authors explore the various subtleties, common failures, and inherent limitations of the theory as it applies to real-world situations, and provide numerous detailed application examples and practice problems, including GNSS-aided INS, modeling of gyros and accelerometers, and SBAS and GBAS.

Drawing upon their many years of experience with GNSS, INS, and the Kalman filter, the authors present numerous design and implementation techniques not found in other professional references. In addition to showing the Kalman filter in action, the software also demonstrates various practical aspects of finite word length arithmetic and the need for alternative algorithms to preserve result accuracy.

 - Коммандер Стратмор у. Советую исчезнуть, пока он тебя не засек. Хейл пожал плечами: - Зато он не имеет ничего против твоего присутствия.

Барабан повернулся. Он снова с силой пнул ногой педаль стартера. Пуля пролетела мимо в тот миг, когда маленький мотоцикл ожил и рванулся .

Увидев их, Джабба сразу превратился в разъяренного быка: - Я не зря создал систему фильтров. - Сквозь строй приказал долго жить, - безучастно произнес Фонтейн. - Это уже не новость, директор.  - Джабба сплюнул.  - От взрывной волны я чуть не упал со стула.

Теперь уже окаменел Стратмор.

В этот момент кровать громко заскрипела: клиент Росио попытался переменить позу. Беккер повернулся к нему и заговорил на беглом немецком: - Noch etwas. Что-нибудь. Что помогло бы мне найти девушку, которая взяла кольцо.

На что же уходит такая уйма времени. - спросил он, обращаясь в пустоту и чувствуя, как покрывается. Наверное, придется потревожить этой новостью Стратмора. Проверка на наличие вируса, - решительно сказал он себе, стараясь успокоиться.
