CTTC develops a Smart Antenna that protects GNSS Receivers from radio frequency interferences


Researchers from the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) have developed a smart antenna for systems that use GPS and/or Galileo receivers for positioning and/or synchronization of distributed networks.

These systems are vulnerable to radio frequency intentional or unintentional interferences that can block signal reception and cause service disruption. The GNSS Smart Antenna developed at CTTC acts as an adaptive spatial filter for those interferences, weeping them off from the radio frequency signal without affecting legit navigation signals before feeding the receiver. The output of this smart antenna can be directly plugged into any existing GNSS receiver, as with any other conventional antenna, offering enhanced robustness and jamming protection to your positioning or timing service.
