Strapdown Associates, Inc. (SAI) is an independent Minnesota corporation founded in 1980.  SAI provides engineering consulting and educational services to aerospace companies and government agencies for design and test of aided and unaided strapdown inertial navigation systems.

Paul G Savage Books In Stock - Strapdown Analytics II,  Intro-To-Strapdown-Nav Course Books

 The second edition of Strapdown Analytics, Paul G Savage's 1,646 page two volume hard cloth cover text detailing all aspects of strapdown inertial navigation analytics, is in stock now only at SAI, and available for purchase.  For a detailed description of these books and ordering information contact SAI by telephone or email as listed above.

 From 1981 to 2009, SAI provided its four and a half day Introductory Course On Strapdown Inertial Navigation Systems to the general public in Minneapolis-Minnesota and on-site at contracting host facilities.  The Introductory Course is no longer being offered, however, the Intro-To-Strapdown-Nav Course Books prepared by the course instructor Paul G Savage are in stock now only at SAI, and available for purchase:

Introduction To Strapdown Inertial Navigation Systems - 712 page "Yellow Book" containing the Introductory course presentation slides with accompanying detailed text descriptions.

Strapdown Inertial Navigation Lecture Notes - 376 page reformatted "Blue Book" providing descriptions of strapdown inertial sensors and derivations of key equations presented in the course.

An Advanced course on strapdown inertial systems is available for the general public that rigorously focuses on the detailed analytical aspects of strapdown inertial navigation.  The advanced course is four and a half days in duration and is provided by Paul G Savage's daughter Kelly Roscoe of Applied Strapdown Analytics (ASA).  The analytical basis for the course is the book Strapdown Analytics provided as one of the advanced course handouts.  The advanced course can be viewed as a quick and easy way to obtain and learn the material presented in the detailed and lengthy Strapdown Analytics.  The next Advanced course open to the general public will be held in Minneapolis during April 18-22, 2011.  For further details select Advanced Strapdown Analytics Course Information

As a primer for the Advanced course including a discussion of how family values and political correctness impacts strapdown inertial navigation, read Geordie's Quaternion Decision.  For thought-provoking answers to fundamental inertial navigation questions, read the trilogy: What Do Inertial Sensors Measure?, What Do Accelerometers Measure?, and What Do Gyros Measure?
