The Study of Electromagnetic Techniques for Space Navigation.
Abstract
Results of scans using a solar template are presented. The data showed no improvement over an iron arc template. The noise due to atmospheric variations becomes negligible at about 500 cps. Consequently, the spectrograph was modified to permit variation of the slit above this frequency. No data have yet been obtained with the modified system. Some preliminary interferometer measurements of the Hg-198 lamp was made following the installation of the equipment on a vibration free pillar in the basement of the building. Some delay was caused by ventilation problems associated with the elimination of ozone generated by the lamp. Initial measurements show that the intensity agrees favorably with that reported by Forrester for his lamp. Results of preliminary studies dealing with the design of equipment for the stellar spectroscopy work are presented. (Author)
