Abstract
Boeing's Manufacturing Research & Development began looking at indoor GPS in 1998, wanting large-scale autonomous measurement inside buildings. They reviewed radio frequency, infrared and ultrasound, then put a prototype out to quote at 0.04 inch accuracy. Five companies were asked; two bid. This is what came of it.
