Sorted by: Date Added To NTRS in Descending order 1 2 Next  Performance of differenced range data types in Voyager navigation Author(s): Taylor, T. H.; Campbell, J. K.; Jacobson, R. A.; Moultrie, B.; Nichols, R. A., Jr.; Riedel, J. E. Abstract: Voyager radio navigation made use of a differenced rage data type for both Saturn encounters because of the low declination singularity of Doppler data. Nearly simultaneous two-way range from two-station baselines was ...
