However, traditional GNSS receiver architectures can hardly meet many mission critical demands, including better than -170 dBm sensitivity, centimeter level accuracy, 100 Hz or higher update frequency, less than 1 watt power consumption, less than 1 second cold start TTFF, etc, particularly considering GNSS
