The present invention relates to a position determination device (100) (and system) for determining and registering an injection location of a liquid drug administered on a body part of a user, wherein the position determination device (100) (and system) comprises a position determination element (110) configured to provide a position signal representing a current location of the position determination device (100), and one or more processing units (150) configured to derive data representing an actual injection location based on the user in response to a current location being determined by the position determination unit (110). The position determination device may be further configured for determining a dosage activity performed by a liquid drug administration device (200) based on obtaining at least one vibration signal from a vibration determination element (110).
