 ### Positioning
-Four major GNSS systems are supported by the **Arduino® Portenta Cat. M1/NB IoT GNSS Shield**. NMEA protocol is used for transmission of GNSS information. An active antenna can be connected via the micro UFL connector (J8) and should have a bias voltage of 3.0V. Input impedance for GNSS antenna connector is 50Ω. For compatibility with all GNSS system, the antenna should support bands over 1559 - 1606 MHz frequency range.
