In particular, they have enabled a new generation of low-cost, high-accuracy, aided INSs suitable for commercial distribution and research test-bed usage. These innovations include small, low-cost inertial sensors; GPS technology; and high-performance, low-cost, floating-point computational equipment. GPS-aided inertial systems have been used for surveying, mining, dredging, automotive, railroad, and aircraft applications for commercial, military, and scientific customers.</font></td><td></td></tr><tr><td colspan="3"></td></tr><tr><td colspan="3" height="1"></td></tr></table><table border="0" cellspacing="0" cellpadding="0"><tr><td rowspan="5"></td> <td colspan="3" height="12"></td> <td rowspan="5"></td></tr><tr><td colspan="3"></td></tr><tr><td></td> <td><font face="Times New Roman, Times, Serif" size="3">The GPS and INSs have complementary characteristics; therefore, it is natural to consider their implementation within an integrated approach. There are several monographs that discuss either GPS or INS, and many journal articles that discuss GPS-aided inertial systems. This is the first book to provide an in-depth treatment of INS, GPS, and their combination into an integrated navigation system, all within a unified framework.</font></td><td></td></tr><tr><td colspan="3"></td></tr><tr><td colspan="3" height="1"></td></tr></table><table border="0" cellspacing="0" cellpadding="0"><tr><td rowspan="5"></td> <td colspan="3" height="12"></td> <td rowspan="5"></td></tr><tr><td colspan="3"></td></tr><tr><td></td> <td><font face="Times New Roman, Times, Serif" size="3">Our objective in writing this book was to provide a single, self-contained reference on GPS, INS, and GPS-aided INS. The text is written with the expectation that the reader has the standard background of a BS-level engineering graduate. We have taken special care in presenting the material at the BS level. For example, the topic of optimal filtering is derived in the context of least squares rather than in the context of stochastic processes. Examples are included throughout the text to relate theoretical concepts back to applications, motivate the importance of specific concepts, and illustrate the pros and cons of alternative techniques. The intended audience for the book includes engineers, students, researchers, scientists, and project managers who may be interested in either designing or using GPS or INS technology in a given application.</font></td><td></td></tr><tr><td colspan="3"></td></tr><tr><td colspan="3" height="1"></td></tr></table><table border="0" cellspacing="0" cellpadding="0"><tr><td rowspan="5"></td> <td colspan="3" height="12"></td> <td rowspan="5"></td></tr><tr><td colspan="3"></td></tr><tr><td></td> <td><font face="Times New Roman, Times, Serif" size="3">In pursuit of our objective to provide a self-contained reference, we have included and discussed various algorithms and issues necessary for implementation. For example, alternative vector transformation parameterization methods (e.g., direction cosine, quaternion) are presented and compared in Chap. 2. Kalman filter implementation issues are discussed in Chap. 4. In App. E the algorithms for correcting GPS pseudoranges and calculating satellite positions are presented. In Chap. 5 the use of this information for GPS-based position and velocity determination is discussed. INS mechanization equations for various approaches are presented in Chap. 6.</font></td><td></td></tr><tr><td colspan="3"></td></tr><tr><td colspan="3" height="1"></td></tr></table><table border="0" cellspacing="0" cellpadding="0"><tr><td rowspan="5"></td> <td colspan="3" height="12"></td> <td rowspan="5"></td></tr><tr><td colspan="3"></td></tr><tr><td></td> <td><font face="Times New Roman, Times, Serif" size="3">Further, the text presents the essential theory and a systematic method for designing and analyzing integrated global positioning and inertial navigation systems.

In Chap. 2 frames of reference, vector transformations, and methods for maintaining the transformations for rotating frames of reference are defined. In Chap. 3 various concepts from systems theory that are necessary to provide an accurate model of the navigation system are presented.
