Abstract

The functionality described herein allows a user device to determine an appropriate juncture at which to initiate processing within a global navigation satellite system (GNSS) dead zone in an energy-efficient manner. In one implementation, the functionality employs a sensor management module for determining when to activate a device movement sensor module provided by a user device. When activated, the user device uses the device movement sensor module to perform any environment-specific processing, such as a dead-reckoning process for determining incremental positions within the venue. Further, in a crowd-sourcing application, the user device may report the incremental positions together with beacon information to remote processing functionality.
