This paper deals with 'Transit', or more correctly the U.S. Navy Navigation Satellite System, NNSS, although its commoner name will be used here. It is a satellite based radio navigational and positioning system, also useful for surveying and geodesy. Navigation has to do with the safe and orderly conduct of a vessel or vehicle on its journeyings, requiring a knowledge of present position, velocity (as a vector) and departure and arrival points. Positioning is the locating of an object relative to its surroundings, not involving motion; while surveying (in this context. is the determination of the relationship of many points relative to each other. Geodesy is the science of providing an accurate network or grid to act as a frame of reference for all three, and hence is the basis without which it should be exceedingly difficult to conduct them. Progress in the use of Transit for all four purposes has been steady and is still being made; it is the object of this paper to describe some of the more outstanding advances.
