Several autonomous satellite navigation configurations were studies on a common low-altitude basis with the emphasis on accuracy and convergence. Analysis was performed by simulations using recursive filtering techniques. Configurations investigated included horizon sensors, unknown landmark tracking, known landmark tracking, and one-way doppler systems. Relevant sensor combinations were analyzed to determine possible performance augmentation. (Author)
