Abstract:
1. A signal processing apparatus, comprising: a synchronizer configured to acquire synchronization with a spreading code of an intermediate frequency signal that is obtained by converting a frequency of a received signal into a predetermined intermediate frequency; a demodulator configured to demodulate a message included in the intermediate frequency signal synchronized by the synchronizer; a measuring unit configured to output a primary signal to a predetermined signal line; and a secondary signal output unit configured to attach a predetermined header to a secondary signal and output the result to the predetermined signal line, wherein the secondary signal includes at least the intermediate frequency signal, or a signal generated from the intermediate frequency signal, the received signal is received from a satellite in a global positioning system, the primary signal includes results of measuring at least one of position, velocity, and time of the signal processing apparatus as measured based on the message that is demodulated by the demodulator.
