Abstract

Methods apparatuses and/or articles of manufacture which may be employed in a mobile device and/or in a location server enable acquisition assistance at the mobile device. In at least one implementation which is not intended to limit claimed subject matter acquisition assistance may include expected Doppler frequency shift and expected code phase in the case of a particular Global Navigation Satellite System (GNSS) satellite vehicle as well as a search window for each of these and a confidence value. The confidence value may indicate the likelihood of detecting signals from the satellite vehicle at the current expected location of the mobile device and within the given search windows and may enable one or more of faster location estimation reduced battery consumption and detection of weaker satellite signals.
