Signal processing apparatus, information processing apparatus, signal processing method, data display method, and program

An information processing apparatus, comprising:

• a primary signal acquirer configured to acquire a primary signal from a predetermined signal line;
• a secondary signal acquirer configured to acquire a secondary signal from the predetermined signal line;
• and a display unit configured to display, on a screen, data corresponding to the primary signal acquired by the primary signal acquirer, and data corresponding to the secondary signal acquired by the secondary signal acquirer, wherein the primary signal includes at least one of position, velocity, and time of the information processing apparatus as measured based on an intermediate frequency signal obtained by converting a frequency of a received signal into an intermediate frequency, the received signal is received from a satellite in a global positioning system, the secondary signal includes at least the intermediate frequency signal, or a signal generated from the intermediate frequency signal, and the secondary signal acquirer acquires the secondary signal from signals output to the predetermined signal line by acquiring a signal whose attached header includes an ID code corresponding to the secondary signal.

A data display method executed using an information processing apparatus configured to display data on a screen, the method comprising the steps of:

• acquiring a primary signal from a predetermined signal line;
• acquiring a secondary signal from the predetermined signal line;
• and displaying, on the screen, data corresponding to the primary signal, and data corresponding to the secondary signal, wherein the primary signal includes at least one of position, velocity, and time of the information processing apparatus as measured based on an intermediate frequency signal obtained by converting a frequency of a received signal into an intermediate frequency, the received signal is received from a satellite in a global positioning system, the secondary signal includes at least the intermediate frequency signal, or a signal generated from the intermediate frequency signal, and the step of acquiring the secondary signal from signals output to the predetermined signal line further includes acquiring a signal whose attached header includes an ID code corresponding to the secondary signal.

A non-transitory computer readable medium including executable instructions, which when executed by a processor that controls an information processing apparatus, cause the processor to function as:

• a primary signal acquirer configured to acquire a primary signal from a predetermined signal line;
• a secondary signal acquirer configured to acquire a secondary signal from the predetermined signal line;
• and a display unit configured to display, on a screen, data corresponding to the primary signal acquired by the primary signal acquirer, and data corresponding to the secondary signal acquired by the secondary signal acquirer, wherein the primary signal includes at least one of position, velocity, and time of the information processing apparatus as measured based on an intermediate frequency signal obtained by converting a frequency of a received signal into an intermediate frequency, the received signal is received from a satellite in a global positioning system, the secondary signal includes at least the intermediate frequency signal, or a signal generated from the intermediate frequency signal, and the secondary signal acquirer acquires the secondary signal from signals output to the predetermined signal line by acquiring a signal whose attached header includes an ID code corresponding to the secondary signal.
