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 of0.0011 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.
