Abstract
Techniques for acquiring Global Navigation Satellite System (GNSS) signals at a mobile device are provided. An example process according to these techniques includes receiving sensor data from at least one sensor of the mobile device, determining one or more blocked zones based on the sensor data in which at least a portion of signals from at least one space vehicle (SV) are blocked by an obstruction, selecting one or more SVs from SV information based on the one or more blocked zones, and attempting to acquire signals from the one or more SVs.
