Another technology that helps Furuno stand apart from its competition is Anti-Jamming. The power level of the GNSS satellite signals when received at the antenna is below the noise floor. Signal processing techniques inside the GNSS receiver allow the extraction of these signals. However, to achieve the highest sensitivity it is critical to keep all sources of noise as low as possible; especially the ones that add in-band noise. These various types of noises such as radio waves or harmonics of the clock are generated from other electronic devices. The use of the Active Anti-Jamming function allows FURUNO's GNSS receiver chips and modules to detect GNSS in-band jamming signals and to remove them. This function is even more effective at detecting and cancelling the narrowband noise and jamming signals, which have a strong impact on GNSS receivers. This function is protecting both the GPS and the GLONASS signal bands. FURUNO‘s GNSS receiver chips and modules demonstrate optimum performance thanks to the Active Anti-Jamming function even when used in environments with high electrical noise.
