This report details results of a course profiling exercise conducted at the Yuma Proving Grounds YPG Arizona using the Nevada Automotive Test Center NATC Dynamic Force Measurement Vehicle DFMV methodology and the Aberdeen Proving Grounds APG inertial profilometer methodology. The rod and level methodology was used to establish the baseline for validation and comparison purposes. Eleven test courses were profiled at YPG. The test course profiled included terrain representative of that used by the Army for ground- based vehicle durability testing. All data acquired was supplied to the U.S. Army Tank-Automotive Command TACOM for further analysis by their simulation department. For each of the eleven courses, a left- and right-wheel path elevation versus distance profile, a left- and right-wheel path wave-number spectrum and coherence function plots were computed from the four wheels on the DFMV. This data was compared to equal data from the rod and level and the inertial profilometer. Volume II contains the data for the different DFMV speeds over each YPG course.
