EXTERNAL SENSOR DATA USAGE FOR IMPROVED DEAD RECKONING

Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) determines a validated heading of the UE, wherein the validated heading is determined based on at least navigational map data stored in a memory of the UE, and determines a dead reckoning position estimate of the UE based on at least the validated heading and sensor information from one or more environmental sensors of the UE.
