This report discusses recent changes in the Armys method of inertial guidance accelerometer applications in order to correlate performance with system cost and accuracy requirements. A recent study of revised test requirements, methods, and techniques in actual test performances are explained, and the results evaluated and depicted using graphs. The major areas covered are test instruments, calculation techniques, centrifuge errors, digital test methods, and linearity requirement background. The Army devised a practical, rapid, and low cost system of evaluating analog accelerometer linearity performance.
