A first failure detector unit compares a signal intensity of the second test signal with a threshold to generate a first failure detection signal. A second failure detector compares the satellites acquired by the first and second demodulator to generate a second failure detection signal. A state determiner determines whether and where a failure exists, using the first and second failure detection signals.
