Abstract
A system and method are provided for delivering orbit and clock corrections for Global Navigation Satellite Systems (GNSS) having: (1) reduced orbit and clock discontinuities when changes in ephemeris message from a satellite occur; (2) reduced quantization error by quantifying quantization error by fitting data within the constraints of the output message to prevent broadcast of large errors; and (3) reduced potential errors caused by old but active data.
