What is the anti-interference module for the unmanned system global satellite navigation system?

The anti-interference module for the unmanned system global satellite navigation system (GNSS) is a specialized hardware/software component specifically designed to protect satellite navigation receivers of unmanned systems (such as unmanned aircraft, unmanned vehicles, unmanned boats, etc.) from intentional or unintentional electromagnetic interference, ensuring that they can continuously and reliably obtain precise position, speed and time information in complex electromagnetic environments. Its core task is to resist interference, that is, to suppress or block the strong radio frequency noise signals of legal GNSS signals (such as GPS, Beidou, GLONASS, Galileo).
