GNSS Jamming is often accompanied by spoofing
Jamming is a form of white-noise RF interference on the same frequency as GNSS signals causing degradation of accuracy or even loss of position. Most spoofing attacks are combined with jamming to remove fallback signals. Jammers are low-cost devices which are easy to set up to produce an RF frequency which drowns out the relatively weak GNSS signals. Septentrio’s renowned AIM+ technology works together with ASP+ to protect the receiver from jamming interference with sophisticated filtering and receiver integrity techniques.
External sensors which promise to protect against GNSS spoofing are available on the market today. However, to ensure overall security and robust operation of your system, it is most effective to have resilience against GNSS spoofing and jamming at the GNSS core. This article explains why secure GPS receivers are crucial for GNSS/INS systems.
