Shiran Geodetic Survey System, Electronic AN/USQ-32(XA-1) Flight Test and Evaluation Program Report

摘要

Testing was accomplished over a six-station network extending from the southern part of Arizona to central Nevada. The photo test area, located near Phoenix, extended 34 miles north-south by 30 miles east-west. The flight test aircraft was an RC-130A. Line crossings were made over all 15 lines in the network and one over water line off Southern California. Data reduction gave a probable error for a line measurement (reduced to geodetic distance) of=0.0011 nautical miles, well within the specification value of =0.0017 nautical miles. Two photomapping flights were conducted. The internal consistency of SHIRAN gave an aircraft location of =12.5 feet within 90 per cent of the measurements. The agreement of aircraft location determined by SHIRAN with the position determined by reduction of the photographic data was =21.6 feet for 90 per cent of the measurements which satisfies the specification requirement of =24 feet.
