The report describes the equipment designed for the Mohole vessel positioning task inculding six major sub-systems. (1) Long-baseline sonar positioning system which receives echoes from four transponders carefully spotted on the ocean bottom near the drill hole; (2) Phase-comparison sonar system beacons, also located on the ocean floor; (3) Radar which is used only for manual reference to four moored surface buoys; (4) Analog computer which receives range information from the sonar reference systems and generates vessel position information and orders to the platform's propulsion units; (5) Data display and control console for use by the vessel's pilot; and (6) Standard shipboard gyrocompass which supplies a true north reference for system operation.
