IMPROVED TIME TO FIRST FIX TTFF SENSITIVITY AND ACCURACY FOR A GLOBAL NAVIGATION SATELLITE SYSTEM POSITIONING DEVICE

摘要

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 behaviours 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.
