Aireon, which provides space-based ADS-B tracking information and other safety services to air navigation service providers (ANSPs), has deployed a GPS interference metric on its safety dashboard. This metric is designed to highlight areas where GPS interference is taking place.

Aireon ADS-B receivers are installed on Iridium Next satellites and enable tracking of ADS-B Out-equipped aircraft anywhere in the world, as long as the aircraft carry an antenna configuration that can interact with the satellites.

The interference metric displays a heat map showing the trending of position integrity category (PIC) and individual position check (IPC) values. PIC is “an industry standard for measuring interference and possible jamming,” according to Aireon, while the IPC value is “an Aireon-unique measure of possible spoofing through time difference of arrival, only possible with Aireon’s global satellite network.”

Identifying areas of GPS interference will help aircraft operators, ANSPs, and other aviation stakeholders gain insights on potential jamming and spoofing activities, according to Aireon. “With this new addition, Aireon’s safety dashboard not only helps to identify potential threats but also empowers ANSPs to take proactive measures, ensuring safer skies for all.”
