  • Page 64 6.2 AIM+: Using the spectrum analyser to detect and mitigate interference The AsteRx-U MARINE Fg is equipped with a sophisticated RF interference monitoring and mitigation system (AIM+). To mitigate the effects of narrow-band interference, 3 notch filters can be configured either in auto or manual mode. These notch filters effectively remove a narrow part of the RF spectrum around the interfering signal.

  • Page 65: Narrowband Interference Mitigation

    6.2. AIM+: USING THE SPECTRUM ANALYSER TO DETECT AND MITIGATE INTERFERENCE 6.2.1 Narrowband interference mitigation Configuring the notch filters In the default auto mode of the notch filters, the receiver performs automatic interference mitigation of the region of the spectrum affected by interference. In manual mode as shown configured for Notch1 in Figure 6-3, the region of the affected spectrum is specified by a centre frequency and a bandwidth which is effectively blanked by the notch filter.

  • Page 66: Wideband Interference Mitigation

    There are also intentional sources of interference from devices such as chirp jammers. The wideband interference mitigation system (WBI) of the AsteRx-U MARINE Fg can reduce the effect of both types of interference on GNSS signals.
