In order to determine the position of a receiver on earth to within a fraction of a mile using high-altitude satellites, 10-meter accuracy in the receiver-satellite ranges or range differences is necessary. The factors that affect ranging systems attempting to achieve such accuracies are considered here rather than the detailed design of a ranging system. It is concluded that the effects of multipath propagation on ranging accuracy for receivers in aircraft must be experimentally studied prior to any judgment of the feasibility of such accuracies. In the absence of multipath, the satellite power and bandwidth requirements and ionospheric and tropospheric effects do not prohibit 10-meter range accuracy.
