    摘要： The invention relates to a position determination system for a motor vehicle (12) for determining whether the motor vehicle is in an area (14, 24) that is covered by a ceiling element of a building, comprising: a receiving unit (13) which is designed to receive navigation signals (Sig1, Sig2, Sig3, Sig4) from a plurality of satellites (Sat1, Sat2, Sat3, Sat4) of one or more global navigation satellite systems and to detect a temporal change of the signal strength of the respective navigation signals. An evaluation unit (15) determines line of sights (LoS1, LoS2, LoS3, LoS4) from the motor vehicle to the respective satellites, the navigation signals of which have been received, evaluates the temporal change of the signal strength of the respective navigation signals with respect to the respectively determined line of sight and determines the entry of the motor vehicle into the covered area by correlation of a driving movement (x) of the motor vehicle with the respective line of sights. The invention also relates to a motor vehicle (12) comprising such a position determination system. The invention further relates to a corresponding method.
