The objective of this report is to write a technical manual for the further development of the Fastrak™ software for the Load Carriage (LC) Simulator. The Fastrak™ system use has been extended to provide phase shift and amplitude information about the motion of the pack relative to the mannequin. A Fastrak™ purpose-built computer program called APLCS was designed to produce specified statistical and graphical reports from the data files. This is a new software analysis program and can be used for several purposes: a) it can examine the frequency content of the pack and person during standardized motions on the LC Simulator, b) it can be used to determine whether a suspension system can be designed to transfer mechanical energy within the gait cycle to assist the person in walking, and c) can be used to create a better dynamic biomechanical model (DBM) as it can help model the actions of the pack-person interface force requirements. The hardware adaptations for use with this software were reported in PWGSC# W7711-0-7632-01 Phase I. This report is designed to document the software program’s functions and replace Section 8.5.3 from the report of PWGSC # W7711-7-7420 Section B of the User’s Manual for the Load Carriage Simulator (V1.02). This report is divided into four sections that describe: data files and their loading, statistical computations, tabular reports and graphical reporting.
