1. A method comprising:

  • receiving, by a wearable device, a location signal from a positioning device having location-determining capabilities indicative of a location of the positioning device, wherein the wearable device includes at least one sensor configured to measure at least one physiological parameter;

    calculating, a first location of the wearable device based, at least in part, on the location of the positioning device and a strength of the location signal received by the wearable device;

    in response to loss of the location signal at the wearable device after calculating the first location of the wearable device;

    storing, on the wearable device, the first location of the wearable device; and

    storing, on the wearable device, wearable device movement data received from one or more movement sensors located on the wearable device and a timestamp associated with the wearable device movement data, wherein the wearable device movement data is indicative of movement of the wearable device; and

    in response to reestablishing the location signal at the wearable device;

    receiving, by the wearable device, an updated location signal from the positioning device and a timestamp associated with the updated location signal, wherein the updated location signal is indicative of one or more updated locations of the positioning device;

    correlating the wearable device movement data and the updated location signal based, at least in part, on their associated timestamps; and

    calculating an updated location of the wearable device based, at least in part, on the wearable device movement data correlated with the updated location signal, a strength of the updated location signal received by the wearable device, and the first location of the wearable device.
