Abstract
Disclosed are methods, systems, and computer-readable medium to perform operations including: generating a ray trace between a device and a global navigation satellite system (GNSS) satellite, where the ray trace includes a reflection off of at least one object; determining, based on the ray trace, a context for a position of the device; and determining the position of the device based on the context and information associated with an access point detected by the device.
Claims20
A method comprising:
- generating a ray trace between a device and a global navigation satellite system (GNSS) satellite, wherein the ray trace comprises a reflection off of at least one object;
- determining, based on the ray trace, a context for a position of the device;
- and
- determining the position of the device based at least on the context and information associated with an access point (AP) detected by the device.
A non-transitory computer-readable storage medium encoded with instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- generating a ray trace between a device and a global navigation satellite system (GNSS) satellite, wherein the ray trace comprises a reflection off of at least one object;
- determining, based on the ray trace, a context for a position of the device;
- and
- determining the position of the device based at least on the context and information associated with an access point (AP) detected by the device.
A device, comprising:
- one or more processors;
- and
- one or more storage devices storing instructions executable by the one or more processors to:
- generate a ray trace between the device and a global navigation satellite system (GNSS) satellite, wherein the ray trace comprises a reflection off of at least one object;
- determine, based on the ray trace, a context for a position of the device;
- and
- determine the position of the device based at least on the context and information associated with an access point (AP) detected by the device.
