    SBAS signals can also be used for navigation, however they have low weighting and therefore only a minor impact on the navigation solution. For receiving correction data, the MIA-M10Q automatically chooses the best SBAS satellite as its primary source.

    This is especially useful when MIA-M10Q is used in cellular applications. • An active antenna can be supplied with the VCC_RF output from MIA-M10Q or from an external supply. VCC_RF is a filtered output voltage supply, which outputs VCC - 0.1 V. In addition, the active antenna supply can be turned on/off...
