"Solidstate SYNCHRO to SIN-COS RESOLVER is utilized to provide the interface between the M.S.C. U2A wind-vane-synchro and the computer analog-to-digital converter. The resolver accepts the five conductor synchro input and outputs two DC voltages (0-10V) proportional to the sine and cosine of the vane angle. Based on the calibration tests of four SYNCHRO to SIN-COS RESOLVERS the maximum error between the actual vane angle and the angle calculated from the resolver outputs was found to be of the order of ±1 degree. At present this method of digitization of wind direction is intended primarily for research applications, however, it also holds considerable promise to be used operationally at airports equipped with a digital computer"--Abstract.
