“A Dead Reckoning/map Correlation System for Automatic Vehicle Tracking”, Thomas W. Lezniak, Richard W. Lewis, Robert A. McMillen1977-02 ()⁠:

An automatic vehicle locating system using self-contained dead reckoning techniques, corrected by central processor map correlation, has been successfully implemented in a production program.

The design studies, development testing, and system implementation of the Fleet Location And Information Reporting System (Boeing FLAIR®) are described.

…A state-of-the-art automatic vehicle tracking system has been developed. The pilot system has had over one million miles of operational vehicle tracking. The present production system has incorporated major improvements in system tracking performance and hardware reliability.
