FIELD: radio navigation.
SUBSTANCE: invention relates to radio navigation. Said technical result is achieved by that position determining device (15) using GNSS interacts with Base service (11) in user equipment (16), UE, wherein position determining device using GNSS receives (23) GNSS satellites signals and navigation data and determines position within TTFF based on said signals/data, and wherein Base service detects (24) user data indicating specific user behavior, and initiates said positioning based on said user data.
EFFECT: technical result is reduction of first positioning time, TTFF, in user equipment, defining position using Global navigation satellite system, GNSS.
