Accuracy of spacecraft landing location on lunar surface determined from post-arrival tracking, considering effect of various mission-dependent parameters
Electronic monitoring system automatically detects and locates minute leaks in seams of large fluid storage tanks and pipelines covered with thermal insulation. The system uses a capacitive tape-sensing element that is adhesively bonded over seams where fluid leaks are likely to occur.
System to locate objects submerged underwater uses active/passive sonar techniques in which a transmitter is attached to the object to be recovered and a receiver is used for search. The system is rugged, has a long term operating life, and furnishes a precise bearing on the object.
Flight reentry experiments define the total heating on a large blunt-nosed body by means of imbedded thermocouples. The thermocouples, installed in a beryllium layered forebody, were designed to provide minimum feasible disturbance of local heat flow with accurate depth control of the thermocouple junction locations.
Thermal emittance behavior of small cavities located on refractory metal surfaces
Wind loads on vertically launched vehicles at various geographic locations and launch altitudes

Meteorological experiment using Omega navigation system for position location of world-wide data collection system
Shape and location of diurnal bulge in upper atmosphere
Effect of quadraloop antenna location on pitch and roll coupling characteristics of Nike-Apache sounding rocket
Omega location and satellite reporting for worldwide observation and navigation systems
Shape and location of diurnal bulge in upper atmosphere, analyzing density and temperature distribution at high latitude from satellite drag data
Static pitching moment coefficient determination from location of center of pressure in right circular cone, using Newtonian impact mechanics
Accuracy of spacecraft landing location on lunar surface determined from postarrival tracking, considering effect of various mission-dependent parameters
Polaroid film is used with conventional portable X ray equipment to locate and shoot items or objects in difficult areas. Polaroid film development time is about 20 seconds.
System locates the focal point of an extremely high intensity electron beam. The electron beam is swept and scanned cyclically with deflection coils under a focusing lens, causing the beam focal point to move so the locus of its positions is a spherical surface symmetrical to the beam axis.
Location of radiation pattern disturbing structures in vicinity of satellite antenna
Hazards monitoring sensors selection and locations for Apollo fuel transfer and tanking system - hypergolic and cryogenic fuel and oxidizer systems
