Examples in accordance with this disclosure provide a system for detecting a spoofed signal, the spoofed signal comprising position-navigation-timing (PNT) data. The sys­tem can include a first antenna and a second antenna, both configured to receive one or more first signals from one or more navigation satellites. The first antenna and second antenna can be configured to be separated by a first distance. The system can include a first receiver coupled to the first antenna and a second receiver coupled to the second antenna, where each antenna is configured to receive one or more signals from the respective antenna. Each receiver is configured to extract its respective carrier phase data.
