Main calculations of separate HDOP/PDOP values of GPS, GLONASS, Galileo and BeiDou are made by GNSS modem. Modem calculates these values, FMB device calculates average HDOP/PDOP from these 4 GNSS systems (Selected in configuration) with a formula below.

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