Send Solutions has engineered an add-on to its Airtext+ Iridium satcom that can not only identify and report GPS jamming or spoofing but also help pilots stay on the proper track when such incidents cause faulty navigation inputs. In addition to the Airtext+ and Iridium antenna, Send’s Spoof Proof system requires an annunciator, either carried on board as temporary equipment or installed in the flight deck. According to Send Solutions, “This is the first independent spoof-proofing product to market.”
During a spoofing attack on an aircraft equipped with global navigation satellite system (GNSS) receivers (which could include GPS, Europe’s Galileo, Russia’s Glonass, China’s BeiDou, India’s Navic, and Japan’s QZSS), incorrect GNSS signals make the aircraft’s navigation system show a position that could be hundreds of miles off course. “The errors created affect a myriad of aircraft navigation [systems] and can send safety equipment into failures,” according to Send Solutions. Jamming overwhelms weak GNSS signals and makes GPS and other GNSS receivers unable to provide position information.
