Download or read book The Long Period Errors of Doppler and Inertial Navigation Systems written by S. G. Smith and published by . This book was released on 1966 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dead reckoning navigation systems making use of gyros have to take account of the earths rotation and the vehicles motion round the earth since these rotations will be sensed by the gyros. In general the gyro correction terms are functions of latitude and therefore the system generates a feedback loop within itself since the final output (latitude) is used to correct the mechanism which is producing this output. By good fortune the sense of this feedback in most cases is such that the errors are oscillatory rather than divergent. The period of oscillation is 24 hours for a stationary I.N. system but in general this is modified by the E-W component of vehicle velocity. The effects are shown to have little significance in Doppler systems but are helpful in some cases of long flights (> 4 hours) with inertial systems. (Author).

Download or read book Arctic Systems written by P. Amaria and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 950 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the purpose of publication of these Proceedings, the original conference programme has been rearranged to provide a more logical sequence of presentation. The beginning sections give the inaugural speech and the six keynote addresses which were delivered at the opening plenary session. Following these are the working papers, published more or less in the same sequence in which they were presented in the original programme. The order of presentation does not necessarily emphasise the importance of any one aspect of the Arctic Systems over others. The final reports of the six working groups and their conclusions and recommendations are edited in such a manner as to present them in a standardised format for easy comprehension. The editors accept responsibility for any distortion inadvertently introduced in the summarising and editing processes. Later sections of the Proceedings give a background to the Conference organization and deliberations, and an independent critique of the meeting. The directors and those who attended the Conference were conscious of the debt of gratitude owed by them to the Conference chairmen, rapporteurs, authors of working papers, and many individuals for their contributions to the success of the meeting. We wish to thank them and it is a pleasure to record their names in these Proceedings. Inaugural Speaker Dr. J. Rennie Whitehead, Canada Banquet Guest Speaker Honourable Mr. T. Alex Hickman, Canada Keynote Addresses Mr. C. Bornemann, Denmark Dr. A.E. Collin, Canada Dr. R.E. Francois, U.S.A.
Download or read book Analysis of an Integrated Inertial doppler satellite Navigation System Part I Theory and Mathematical Model written by R. Grover Brown and published by . This book was released on 1969 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inertial navigation systems have reached a high level of sophistication in recent years, but the effect of long-term-drift is still a problem in many applications. It has been demonstrated that position fixes obtained from the Navy Navigation Satellite System may be used to update an inertial system, but simple position updating can not correct the underlying causes of the drift nor can it correct the Schuler oscillation in the undamped case. This report describes a method of system integration whereby the Doppler data is treated directly as the observable in a Kalman-filter reset scheme. The advantage of this approach is that estimates of the inertial velocity and gyro bias errors are obtained as well as the position errors. Thus, the additional information obtained from the Kalman filter can be used to reduce the rate of error propagation in the interim between passes. Details of the Kalman filter model are presented in the report. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: For the latest twenty to thirty years, a significant number of AUVs has been created for the solving of wide spectrum of scientific and applied tasks of ocean development and research. For the short time period the AUVs have shown the efficiency at performance of complex search and inspection works and opened a number of new important applications. Initially the information about AUVs had mainly review-advertising character but now more attention is paid to practical achievements, problems and systems technologies. AUVs are losing their prototype status and have become a fully operational, reliable and effective tool and modern multi-purpose AUVs represent the new class of underwater robotic objects with inherent tasks and practical applications, particular features of technology, systems structure and functional properties.

It summarizes the A–Z of the background and application knowledge of ocean engineering for use by ocean scientists and ocean engineers as well as nonspecialists such as engineers and scientists from all disciplines, economists, students, and politicians. Ocean engineering theories, ocean devices and equipment, ocean design and operation technologies are described by international experts, many from industry and each entry offers an introduction and references for further study, making current technology and operating practices available for future generations to learn from. The book also furthers our understanding of the current state of the art, leading to new and more efficient technologies with breakthroughs from new theory and materials.
