Abstract
GNSS receiver duty cycling is based on context awareness. Context awareness can be received signal quality, targeted navigation performance, and external information extracted from other sensors or being received from other sources such as cellular system, Wi-Fi, camera, LiDAR, and Bluetooth Low Energy (BLE).
Claims20
A system comprising:
- at least one global navigation satellite system (GNSS) enabled device;
- at least one location device different from the location device;
- and
- at least one processor is establishing a low power mode period of the GNSS device responsive to identifying a difference in indicated locations between the GNSS device and the location and/or motion device.
1 more element
An article of manufacture, comprising:
- at least one computer storage that is not a transitory signal and that comprises instructions executable by at least one processor to:
- receive global navigation satellite system (GNSS) signals from a GNSS receiver;
- identify at least one signal quality based on the signals;
- establish a low power mode period length for the GNSS receiver based at least in part on the signal quality;
- establish a low power mode for a GNSS device associated with the GNSS receiver;
- and
- at an end of the low power mode period, establish a full power mode for the GNSS device.
4 more elements
A method, comprising:
- receiving an indicated location from a global navigation satellite system (GNSS) receiver;
- receiving an indicated location from a location device other than the GNSS receiver;
- and
- establishing a length of a low power mode period for the GNSS receiver based at least in part on a relationship between the indicated locations.
