STUDY OF ELECTROMAGNETIC TECHNIQUES FOR SPACE NAVIGATION

Abstract

Tests made with engraved templates verified that very narrow lines and high contrast are important in achieving good S/N ratios. Wobbulation at 500 cps has proved effective in eliminating most of the effects of noise from atmosphere sources, and a phase detector and integrator developed for use at this frequency is expected to reduce residual uncertainties even further. Design of the stellar spectrograph was about completed. (Author)
