1. A method for estimating a position location of a mobile device, comprising: receiving position location data from a plurality of sources including at least a satellite system and a base transceiver station;comparing the received position location data at the mobile device;marking inconsistent data based on the comparison at the mobile device; andestimating the position location based on the received position location data at the mobile device, while accounting for the marked inconsistent data, in which estimating includes discarding or de-weighting the marked inconsistent data that is potentially associated with a spoofing signal. 2. The method of claim 1, in which the marking comprises marking inconsistent data based upon a reliability of each data source. 3. The method of claim 2, in which the reliability of each data source is based upon a hierarchy, the hierarchy comprising a base transceiver station in communication with the mobile device, a satellite system, and a short-ranged wireless protocol access point. 4. The method of claim 1, further comprising sending notification of the marked inconsistent data. 5. The method of claim 1, in which the marking comprises marking inconsistent data that is inconsistent with a majority of the received position location data. 6. The method of claim 1, in which the comparing comprises determining whether a location solution converges. 7. The method of claim 1, in which the comparing comprises determining whether the estimated position location exceeds an error estimate. 8. The method of claim 1, in which the comparing comprises comparing visible satellite data with estimated satellite data, the estimated satellite data being derived based upon a seed location. 9. A non-transitory computer-readable storage medium including program code tangibly stored thereon, comprising: program code to receive position location data from a plurality of sources including at least a satellite system and a base transceiver station;program code to compare the position location data at a mobile device;program code to mark inconsistent data based on the comparison at the mobile device; andprogram code to estimate a position location based on the received position location data at the mobile device, while accounting for the marked inconsistent data, in which to estimate includes discarding or de-weighting the marked inconsistent data that is potentially associated with a spoofing signal. 10. The medium of claim 9, in which the marking comprises marking inconsistent data based upon a reliability of each data source. 11. The medium of claim 9, in which the marking comprises marking inconsistent data that is inconsistent with a majority of the received position location data. 12. The medium of claim 9, in which the comparing comprises determining whether a location solution converges. 13. The medium of claim 9, in which the comparing comprises determining whether the estimated position location exceeds an error estimate. 14. An apparatus for estimating a position location, comprising: at least one receiver that receives position location data from a plurality of sources including at least a satellite system and a base transceiver station;a processor in a mobile device configured to compare the received position location data, mark inconsistent data based on the comparison, and estimate the position location based on the received position location data, while accounting for the marked inconsistent data, in which estimating includes discarding or de-weighting the marked inconsistent data that is potentially associated with a spoofing signal. 15. The apparatus of claim 14, in which the processor is further configured to mark inconsistent data based upon a reliability of each data source. 16. The apparatus of claim 14, in which the processor is further configured to mark inconsistent data that is inconsistent with a majority of the received position location data. 17. The apparatus of claim 14, in which the processor is further configured to determine whether a location solution converges. 18. The apparatus of claim 14, in which the processor is further configured to determine whether the estimated position location exceeds an error estimate. 19. An apparatus for estimating a position location, comprising: means for receiving position location data from a plurality of sources including at least a satellite system and a base transceiver station;means for comparing the received position location data at a mobile device;means for marking inconsistent data based on the comparison at the mobile device; andmeans for estimating the position location based on the received position location data at the mobile device, while accounting for the marked inconsistent data, in which estimating includes discarding or de-weighting the marked inconsistent data that is potentially associated with a spoofing signal.
