Wearable satellite receiver with reduced power consumption

A method comprising:

• determining, while a position acquisition device is in a low power state in which the position acquisition device is unable to obtain location information and based on a command to capture an image with a camera, that a configurable setting indicates that a first location is to be captured and stored in association with a captured image;
• configuring, in response to the configurable setting, the position acquisition device into an operative state to determine a second location of a wearable electronic device;
• activating an accelerometer in response to determining that the configurable setting indicates that the first location is to be captured and stored in association with the captured image;
• in response to the command to capture the image and in response to activating the accelerometer, storing acceleration measurements from the accelerometer until at least the position acquisition device obtains the second location of the wearable electronic device;
• and
• determining the first location based on the accelerometer measurements and the second location.

A non-transitory computer readable medium comprising instructions that when executed configure hardware processing circuitry to perform operations comprising:

• determining, while a position acquisition device is in a low power state in which the position acquisition device is unable to obtain location information and based on a command to capture an image with a camera, that a configurable setting indicates that a first location is to be captured and stored in association with a captured image;
• configuring, in response to the configurable setting, the position acquisition device into an operative state to determine a second location of a wearable electronic device;
• activating an accelerometer in response to determining that the configurable setting indicates that the first location is to be captured and stored in association with the captured image;
• in response to the command to capture the image and in response to activating the accelerometer, storing acceleration measurements from the accelerometer until at least the position acquisition device obtains the second location of the wearable electronic device;
