A combination mobile phone and navigation satellite receiver comprises a circuit for correcting GPS receiver reference frequency drift by using VCO burst information periodically received by a PDC handset. A corrected GPS receiver reference frequency drift then enables faster initialization and stable operation of the position solutions made available to users. A GPS numeric controlled oscillator (NCO) receives a PDC handset VCO sample.
