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.

A method for acquiring Global Navigation Satellite System (GNSS) signals at a mobile device, the method comprising:
- receiving sensor data from at least one sensor of the mobile device;
- determining one or more blocked zones, in which at least a portion of signals from at least one space vehicle (SV) are blocked by an obstruction, and a level of obstruction associated with each of the blocked zones based on the sensor data;
- selecting one or more space vehicles (SVs) from SV information based on the one or more blocked zones, wherein selecting the one or more SVs from the SV information comprises accessing the SV information of one or more GNSSs and prioritizing SVs associated with the one or more blocked zones based at least in part on the level of obstruction associated with each of the one or more blocked zones;
- and
- attempting to acquire signals from the selected one or more SVs.
An apparatus comprising:
- means for receiving sensor data from at least one sensor of a mobile device;
- means for determining one or more blocked zones, in which at least a portion of signals from at least one space vehicle (SV) are blocked by an obstruction, and a level of obstruction associated with each of the blocked zones based on the sensor data;
- means for selecting one or more space vehicles (SVs) from SV information based on the one or more blocked zones, wherein the means for selecting further comprises means for accessing the SV information of one or more Global Navigation Satellite Systems (GNSSs) and means for prioritizing SVs associated with the one or more blocked zones based at least in part on the level of obstruction associated with each of the one or more blocked zones;
- and
- means for attempting to acquire signals from the one or more SVs.
A mobile device comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor being configured to:
- receive sensor data from at least one sensor of the mobile device;
- determine one or more blocked zones, in which at least a portion of signals from at least one space vehicle (SV) are blocked by an obstruction, and a level of obstruction associated with each of the blocked zones based on the sensor data;
- select one or more space vehicles (SVs) from SV information based on the one or more blocked zones, wherein the processor is configured to access the SV information of one or more Global Navigation Satellite Systems (GNSSs) and to prioritize SVs associated with the one or more blocked zones based at least in part on the level of obstruction associated with each of the one or more blocked zones;
- and
- attempt to acquire signals from the one or more SVs.
A non-transitory, computer-readable medium, having stored thereon computer-readable instructions for acquiring Global Navigation Satellite System (GNSS) signals at a mobile device, comprising instructions configured to cause a computer to:
- receive sensor data from at least one sensor of the mobile device;
- determine one or more blocked zones, in which at least a portion of signals from at least one space vehicle (SV) are blocked by an obstruction, and a level of obstruction associated with each of the blocked zones based on the sensor data;
- select one or more space vehicles (SVs) from SV information based on the one or more blocked zones, wherein the instructions configured to cause the computer to select the one or more SVs further comprise instructions configured to cause the computer to access the SV information of one or more GNSSs and to prioritize SVs associated with the one or more blocked zones based at least in part on the level of obstruction associated with each of the one or more blocked zones;
- and
- attempt to acquire signals from the one or more SVs.
