Summary: Best book for Implementation in field of Navigation
Review: Book was written based on the really application. It works great not only in the theory, but also in the field of practice. The best and easy book used to build DGPS/INS for real time application.

Summary: Who edited this?
Review: I have struggled throught the first 2 chapters of this book and can't believe how poorly written this is. Mathematical derivations suffer from "logic leaps" that are not at all intuitive. Coordinate frame definitions are adequate, but more figures are needed. The text references figures with Greek symbols. When you go to the figure the symbol is missing or changed to another symbol. There are some math errors that are obvious, but when trying to use a text as a reference I don't think it's my job to double check the author's math! I contacted McGraw Hill about an errata sheet for the text. They don't have one available, but said they would be glad to accept my inputs. Can I trust this book as a reference? I don't know! I'm a complete novice in the field of Inertial Navigation and I don't feel I'm qualified to "edit" their book for them. This is a poorly written book because it assumes the audience is as well versed in Inertial Navigation and GPS as the author. One final gripe is that Mathematical Notation is referenced in Appendix A of the text. When trying to read the body of text, you must constantly refer to this appendix to try and figure out what the author is trying to convey. It's not bad, but it makes reading tiring and slow! The appendix is fine, but the introductory chapters in a well written text normally introduce the reader to the notation gradually, explaining symbols and conventions. Later chapters can then use less and less explanatory text for notation. This book could really be a "home-run" with some good editing and a second printing.

Summary: Mixed Results
Review: I purchased this book mostly for its technical content and less for its descriptive narrative about inertial nav and GPS. My goal was to use the book as a basis for some analysis. Unfortunately, I can't recommend the book to someone who can't re-derive the equations in the book.

One reviewer from New Mexico wrote: "There are some math errors [in Farrell & Barth's book] that are obvious, but when trying to use a text as a reference I don't think it's my job to double check the author's math!" But, lo! I think one NEEDS to check the math in this book because even the most trivial of computations can and do have errors in them. For example, one thing really irksome about the book is that the matrix representation for the cross product operation in Appendix A has an overall factor of (-1) buried in it -- and it's wrong. Then the authors happily propagate this interesting "sign convention" throughout the book, meaning that you have to do a double take each time the book uses it. It's a horrendous mess.

The same NM reviewer also asked: "Can I trust this book as a reference?" I think it's hit or miss. I spent over a week deriving and implementing the equations in Chapter 6. And even though I have some experience with coordinate frames and dynamics in rotating frames, it took a lot of effort to work through everything myself and correct the errors. Luckily most of the final equations are, indeed, correct in Chapter 6 -- save for a sign or two. On the other hand, I'm still trying to find the book's sign errors in the mapping from the quaternions to the Euler angles (Chapter 2). Is there really an error? Or am I doing something stupid? With this book, I'll have to figure it out for myself.

This book has the potential to become an excellent reference and resource for inertial nav and/or GPS nav information. But as it stands, it's a sketch of a book that leaves it up to the reader to wonder whether it's him/her that's missed the point, or the authors who mangled yet another equation.

Summary: An aerospace engineering student
Review: This is a great book for the student. It goes over the basics of GPS and inertial navigaion. I found the development of the equations and models of the systems invaluable. I have used this book as the basis of many useful functions for transforming from latitude/longitude/altitude to ECEF and others. Overall, a great book for the beginner, although, a bit weak on advanced topics.
