INTERFERENCE DETECTION MECHANISM FOR SATELLITE POSITIONING RADIO WAVE, AUGMENTATION INFORMATION TRANSMISSION SYSTEM COMPRISING THE SAME, AND INTERFERENCE DETECTION METHOD FOR SATELLITE POSITIONING RADIO WAVE
Provided is a satellite positioning-use radio wave interference detection mechanism that can determine with a high degree of accuracy whether there is radio wave interference with a GPS signal, without increasing processing load. The satellite positioning-use radio wave interference detection mechanism comprises: a signal-to-noise ratio acquisition means that acquires a signal-to-noise ratio for a received GPS signal; a rate of change calculation means that calculates a time rate of change within a prescribed period of time with respect to the signal-to-noise ratio; and a determination means that determines whether there is radio wave interference with the received GPS signal, on the basis of the calculated time rate of change.
