You can view GNSS firmware from DashboardGNSS (main) or EquipmentGNSS (main). From here, select the About tab to see the firmware information.
Caution: When you upload firmware files, make sure that you select the .ITB file for the main board firmware and .LDR and .LDP files for the GNSS firmware. If you load the incorrect file, a firmware load error shows and failure of the main board will occur.
