14. A mobile device configured to support satellite positioning system (SPS) operation, the mobile device comprising:
a satellite positioning system (SPS) receiver configured to receive SPS signals over a plurality of frequency bands;
a processor coupled to the SPS receiver and configured to:
receive a first positioning signal from a satellite vehicle (SV);
receive a second positioning signal from the same SV as the first positioning signal;
measure a first carrier phase (CP) measurement of the first positioning signal at a first time and a second CP measurement of the first positioning signal at a second time;
perform a third CP measurement of the second positioning signal at a third time and a fourth CP measurement of the second positioning signal at a fourth time; and
estimate a corrected second CP measurement of the first positioning signal by selecting an integer value of the corrected second CP measurement using a difference between the third CP measurement and the fourth CP measurement of the second positioning signal and selecting a fractional value of the second CP measurement to be a fractional value of the corrected second CP measurement.
