Download or read book Sensitivity of Track Accuracy to Navigation Sensor and Time Errors Within a Distributed System written by and published by . This book was released on 2004 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of achieving a Single Integrated Air Picture (SIAP) is a function of the accuracy with which the positional estimates of aerospace objects can be made. This report presents a detailed analysis of how track accuracy is affected by navigation, sensor, and time errors, which include errors due to time synchronization, time stamping, time latency, etc. Although the analysis assumes a shipborne sensor system for illustrative purposes, the analysis is general and can be applied to all sensing systems that comprise the distributed system that develops and maintains the SIAP. Navigation errors are the result of errors in the accelerometers and gyroscopes forming the inertial navigation system. The focus here is not on the errors in the individual inertial instruments but on their performance as they affect the uncertainty in the position of the inertial navigation system and the orientation of the navigation reference frame. Navigation positional uncertainty or error is described by error in the north position, east position, and height of the navigation system. Error in the orientation of the navigation reference frame is described by three misalignments that represent the cumulative effect of the gyroscopes' inability to maintain a perfect inertial reference. Errors in navigation position translate directly into errors in track measurement. A 300 m east position error results in a 300 m track error. Navigation misalignments also have a significant effect on track accuracy. A I mrad misalignment about all three navigation reference axes results in a track error of 260 m for objects 100 nm away. The misalignment contribution is proportional to range to the object. Thus, for an object 10 nm from the ship, the 1 mrad misalignment contribution is 26 m.
Download or read book Sensitivity of Track Velocity Error to Data Registration and Dynamic Errors Within a Distributed System written by and published by . This book was released on 2004 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of accurately tracking an aerospace object is strongly dependent on how well the position, velocity, and acceleration of the object is known. Understanding what contributes to errors in these quantities, and how, is important in predicting the performance of a tracking system or as in the case of a Single Integrated Air Picture (SIAP) a distributed tracking system. A previous JSSEO Technical Report investigated position estimate errors as a function of data registration and dynamic errors. The Technical Report is a complement to that earlier analysis and outlines a similar methodology for understanding and investigating track velocity estimate errors. The study of velocity estimate errors is relevant not only to the general problem of aerospace object tracking, but also to the analysis of specific operational threads. For example, in an Integrated Fire Control(IFC) engagement, the interceptor will use positional and velocity information about the target. Therefore, knowledge of the errors in both the position and velocity estimates is important to predicting system performance.

This book was released on 2012-09-14 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title analyzes distributed Earth observation missions from different perspectives. In particular, the issues arising when the payloads are distributed on different satellites are considered from both the theoretical and practical points of view. Moreover, the problems of designing, measuring, and controlling relative trajectories are thoroughly presented in relation to theory and applicable technologies. Then, the technological challenges to design satellites able to support such missions are tackled. An ample and detailed description of missions and studies complements the book subject.

Download or read book Springer Handbook of Global Navigation Satellite Systems written by Peter Teunissen and published by Springer. This book was released on 2017-06-16 with total page 1335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Handbook presents a complete and rigorous overview of the fundamentals, methods and applications of the multidisciplinary field of Global Navigation Satellite Systems (GNSS), providing an exhaustive, one-stop reference work and a state-of-the-art description of GNSS as a key technology for science and society at large. All global and regional satellite navigation systems, both those currently in operation and those under development (GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS/NAVIC, SBAS), are examined in detail. The functional principles of receivers and antennas, as well as the advanced algorithms and models for GNSS parameter estimation, are rigorously discussed. The book covers the broad and diverse range of land, marine, air and space applications, from everyday GNSS to high-precision scientific applications and provides detailed descriptions of the most widely used GNSS format standards, covering receiver formats as well as IGS product and meta-data formats. The full coverage of the field of GNSS is presented in seven parts, from its fundamentals, through the treatment of global and regional navigation satellite systems, of receivers and antennas, and of algorithms and models, up to the broad and diverse range of applications in the areas of positioning and navigation, surveying, geodesy and geodynamics, and remote sensing and timing. Each chapter is written by international experts and amply illustrated with figures and photographs, making the book an invaluable resource for scientists, engineers, students and institutions alike.
