Abstract:

Project Transit is the code name of a program aimed at achieving a world-wide, all-weather navigation system. The system is based on the fact that the orbital parameters of an earth satellite can be determined by analyzing the doppler frequency shift in radio frequency signals transmitted by the satellite. Then, conversely, if the orbital parameters are known, an observers location can be accurately determined. The development of this concept into a complete navigation system is being pursued. This report covers the development of the Transit Navigation Satellite power system and deals with the silicon photovoltaic converters, the rechargeable nickelcadmium batteries, the zinc-silver oxide batteries used in an early version, and the static conversion equipment. The requirements and test conditions are discussed with data presented which summarizes the telemetered data from the orbiting vehicles. Author
