Abstract

The present invention relates to a method for improving Time To First Fix, TTFF, sensitivity and accuracy, wherein a Global Navigation Satellite System, GNSS, positioning device (15), communicates with a Core Service (11) in a User Equipment (16), U—the GNSS positioning device acquires (23) GNSS satellite signals and navigation data and based on said signals/data determines a position within TTFF,—the Core Service detects (24) user data indicating specific user behaviors and initiates said determination of position based on said user data. The present invention also relates to a Core Service, a Global Navigation Satellite System, GNSS, positioning device, a Radio Module and a User Equipment, UE, adapted for the same purpose.
