The GPS Pocketbook

The GPS Pocketbook is a 48 page booklet I have co-written with Dr. Per Bennich. It contains the most important and most fundamental information about the tolerance indications of the GPS system and how they are used to express tolerancing clearly and unequivocally in an engineering drawing. You can find more information here.
