MAP-AIDED SATELLITE SELECTION

Abstract:

Techniques for map-aided satellite selection are provided. An example of a method for determining a location according to the disclosure includes determining a future trajectory of a user equipment, estimating an environment model associated with the future trajectory, determining a plurality of expected navigation satellites based on the future trajectory and the environment model, selecting a set of navigation satellites to use in computing the current location based in part on the plurality of expected navigation satellites, and computing the current location based on the selected set of navigation satellites.
