# GNSS Configuration

The module can be configured through the USB-C port using standard GNSS configuration tools. This allows advanced settings such as:

* Selecting/deselecting individual GNSS constellations
* Adjusting update rates
* Enabling/disabling raw measurements
* Configuring PPS output frequency
* Saving configuration to non-volatile memory

#### Default Configuration

* Output: NMEA messages on UART1 (1 Hz)
* GNSS Constellations: GPS, Galileo, BeiDou, GLONASS, NavIC, QZSS
* Bands: L1, L2, L5, L6 enabled
* PPS Output: Enabled at 1 Hz
