Abstract:	A baseline assessment is provided for the worldwide hyperbolic position-fix accuracy of the OMEGA Navigation System. The assessment is performed by evaluating the fix errors obtained using a single-frequency, hyperbolic fix algorithm, and the Morris/Swanson propagation correction prediction model. Position-fix statistical measures are computed for each monitor site and LOP pair available in 5 years of phase-difference data selected from the OMEGA MASTERFILE. The worldwide distributions of position-fix measures are then displayed for two selected OMEGA fix-geometry criteria: GDOP less than 10, and best-available GDOP at each site.
