Automatically fetch the GNSS assistance data from the Web to heavily reduce the time to acquire a GNSS lock by uploading the assistance data to the modem. This feature is optional and can be disabled in the configuration as people may prefer to not download the assistance data from the Quectel/Qualcomm servers. Also configure the GNSS engine to optimize the performance and power consumption.
