Observations of Lightweight Doppler System Accuracy.
Abstract
Data on the accuracy of the Lightweight Doppler Navigation System (LDNS) fitted to a Royal Australia Air Force UH-1H helicopter were gathered as a by-product of an experiment on the TACTERM navigation system. The observed accuracy was found to be close to 1% of distance travelled, a figure generally considered to be representative of modern doppler navigation systems. The dominant source of LDNS position error was magnetic compass error which in turn appeared to be dominated by spatial and temporal variations in the local magnetical field.
