    The book has three closely connected parts.  The first is Linear Algebra,
which is the fundamental tool in positioning calculations.  The second is
Geodesy, which includes the correct weightings for observation errors and
the development of least squares.  The third is GPS, which we describe in
detail at several levels : first the basic structure of the GPS system, then
the algorithms that yield accurate positions from inaccurate pseudoranges,
and finally the Kalman filtering (and "Bayes" filtering) that give superior
accuracy in postprocessing a long series of observations.

    If you wanted to order this book, I only need to ask for email with the best
mailing address.  The book will come with an invoice ; a check to the Press
(not credit card) is perfect.  The cost including domestic postage is $60.
Orders can equally well go to Wellesley-Cambridge Press (fax 617 253 4358).

    For international orders the cost with surface postage is $62.  I now
recommend the new Global Priority Airmail (if available to your country)
which only adds $5 to that cost. Personal checks in US dollars or
Eurocheques in English pounds are fine.  Often the easiest is cash to
the Press and it is amazingly safe ; we take all risk. 
**Please let me know what you prefer and the Press will follow through.**

    A large library of MATLAB files is associated with the book.   They were
created by Kai Borre and are freely available on the web.  We hope that these
M-files will help readers to use the more individual and experimental
processing that MATLAB offers, compared with large-scale software packages.

    I will enclose the Table of Contents below.  I would be very grateful
if you could make this book known to friends.  You could send them this
message and/or just show them the book !  Most of all I hope you will enjoy 
this presentation of a technology that is developing so fast.  

        With thanks and very best regards,     Gilbert Strang
