1. A method for triggering acquisition of geolocation fix information comprising: obtaining sensor information from at least one sensor; determining, using the sensor information, activity state information based on: determining normalization information on the sensor information; extracting a sliding window based on the normalization information; and computing features from time-domain information and frequency-domain information based on a magnitude of a frequency response obtained based on the sliding window; determining whether an activity state has transitioned between particular activity states based on the activity state information; and triggering geolocation fix information based on a determination that activity state transitions between the particular activity states.
