|[[File:Alert.png|left|link=|50px]]||<b>From firmware version 03.27.06.Rev.01 HDOP/PDOP value calculation has been removed. DOP values are taken from GPGSA messages. DOP values are calculated according to constellations that are currently in use. Example: If we have 4 GNSS systems and there will be two in use then average will be calculated from two GNSS systems.</b>

Main calculations of separate HDOP/PDOP values of GPS, GLONASS, Galileo and BeiDou are made by GNSS modem. GNSS Modem already  outputs average of HDOP/PDOP from  4 GNSS systems (Used satellites) with a formula below.

Calculation formula - ("GPS" + "GLONASS" + "Galileo (0-sat)" + "BeiDou (0-sat)") / 2 (four GNSS systems)**<BR>

Calculation formula - ("GPS" + "GLONASS") / 2 (two GNSS systems)<BR>

HDOP/PDOP will be different if it will have 19 and i.e. other packet with  6 satellites. In parsed regular AVL packet example below all of 19 satellites are shown as in use.
