Embodiments provide for a positioning device comprising a global navigation satellite system (GNSS) receiving unit, a communication antenna and a communication module. The GNSS receiving unit is adapted to receive satellite information. The communication antenna allows for reception and/or transmission of complementary data. The communication module is connectable to the GNSS receiving unit and the communication antenna. The communication module is configured to provide complementary data received at the communication antenna to the GNSS receiving unit and/or to provide complementary data generated at the GNSS receiving unit to the communication antenna. The communication module is detachable or switchable for adaptation to an available communication technology.
