Abstract: A global navigation satellite system (GNSS) receiver includes an internal signal processor configured to perform an internal signal processing operation on a satellite signal to generate satellite information, a switching circuit configured to transmit the satellite signal to the internal signal processor, and a control circuit configured to receive a blanking signal from an external communication device instructing that the internal signal processing operation is to be blocked, and configured to output control information for reducing transmission power of the external communication device and to control the switching circuit to transmit the satellite signal to the internal signal processor regardless of the blanking signal when a frequency at which the blanking signal is received exceeds a reference value.

Abstract: A GNSS receiver includes a RF unit, a baseband processing unit, a storage unit, a mode control unit and a counter unit. The RF unit receives a satellite signal from an external satellite. The baseband processing unit determines present operation environment of the GNSS receiver based on the satellite signal. The storage unit stores information received by the RF unit and information generated by the baseband processing unit. The mode control unit controls an operation mode of the GNSS receiver based on the present operation environment. The operation mode includes a normal mode and a low power mode. The counter unit counts a first number representing a number of consecutive times in which the GNSS receiver has entered the low power mode. When the GNSS receiver enters the low power mode, the mode control unit turns off at least one of the RF unit, the baseband processing unit and the storage unit based on the first number.
