A controller of an interference wave signal remover detects the interference wave signal based on a frequency scanning result by an entire-range frequency scanner, and sets a notch filter to attenuate the interference wave signal frequency. A local scan frequency band BWfL of a local frequency scanner is set by having the interference wave signal frequency as its central frequency, and local scan frequencies BINL are set so that frequency bands overlap with each other between adjacent frequency BINA. The local frequency scanner frequency-scans input signals to the notch filter. The controller calculates a frequency error δf of the interference wave signal frequency from the local frequency scanner, corrects the interference wave signal frequency which is from the entire-range frequency scanner by the frequency error δf, and updates the setting of the notch filter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Interference wave signal removing device, GNSS reception apparatus, mobile terminal, interference wave signal removing program and interference wave removing method","description":"An interference wave signal frequency is highly accurate and the interference wave signal is surely removed.
