Raytheon Technologies is developing receivers planned to provide an alternative navigation system to GPS that integrates sensors and signals through concepts such as machine learning.

Raytheon's intelligence and space business said Monday the navigation technology features an Application-Specific Integrated Circuit that works to process signals to support the receiver's anti-spoofing and anti-jamming elements.

ASICs have the capacity to ingest data from sources including radio frequencies, visual recognition systems like radars and cameras, accelerometers, magnetic sensors and other positioning, navigation and timing technologies.

Ben Graham, director for resilient navigation and reconnaissance systems at RI&S, noted that Raytheon's new technology is meant to support continued operations in GPS-denied environments.

Jarrett Perry, program area chief engineer for the same RI&S division, said the company looks to finish building a ground-based receiver system prototype for combat operations in 2024. Fielding is currently scheduled for 2025.

The National Defense Authorization Act of 2021 mandates the Department of Defense to ensure that more resilient PNT options are available, according to Raytheon.
