# GnssSignalTypes

Specifies the GNSS signal type and RF band for jammer information and automatic gain control metric in [GnssData](https://docs.qualcomm.com/doc/80-80023-25/topic/GnssData.html#gnss-data). To find out the jammer information and automatic gain control metric for a particular GNSS signal type, refer to the array element with index set to the signal type.
