Surveyor I spacecraft was soft-landed on lunar surface 18.96 km from desired location; Surveyor III was landed 2.76 km from its desired location; landings were within predicted regions of uncertainty as determined in flight, approximately 39 km and 15 km, three standard deviations, respectively; major sources of landing site error are orbit determination computational accuracy and spacecraft hardwad tolerance uncertainties; preflight error analysis was in good arrangement with in-flight results; landing locations were determined from Lunar Orbiter and spacecraft photographs along with Earth-based ratio tracking data.
