SATELLITE DOPPLER NAVIGATION FOR SMALL CRAFT.
Abstract
The paper presents a method for obtaining a navigation fix that is suitable for small craft which uses measurements of the satellite radio Doppler shift and published tables. The method utilizes integral doppler data taken in the same manner as the AN/SRN-9 equipment but changes the times at which the doppler count triggers are transmitted from the satellite. The solution tables to determine the navigator's position relative to the satellite are new. The form of the solution tables are factored such that accurate time and frequency standards on board the navigating craft are not needed. The accuracy of the navigation fix is essentially the same as the AN/SRM-9 equipment if the navigatior is willing to hand compute several fine corrections. The navigation fix with no corrections should be accurate to about one or two nautical miles. (Author)
