From page 55...
... If errors from SA are removed and ionospheric errors are minimized by using dualfrequency receivers, clock and ephemeris errors become dominant. Improvements to the GPS space and ground control segments will be required in order to reduce these errors.s3 Time Synchronization For the telecommunications industry, requirements such as integrity and availability fall under the general category of overall system reliability.
