Abstract:	SEVERAL CONFIG~URATIONS of hyperbolic position fixing systems using synchronous satellites are formulated and examined. The Loran-like networks of spherical hyperbolas on the earth that result from these configurations are shown, from which the coverage area and crossing angles of the lines of position are easily visualized. The propagation of errors in both the pure satellite system and the satellite-ground station hybrids is then described analytically by a single set of position error equations. Major problems in implementing these system concepts are anticipated and possible ways of solving them are suggested. The variability and accuracy with which the system parameters will be known to various classes of users are estimated, and these are combined in the error analysis to give an indication of the fis accuracy which can be expected. Numerical results of the Drms error statistic are tabulated.
