Carry-on gps spoofing detector

A method for detecting a spoofed signal, the spoofed signal comprising position-navigation-timing (PNT) data, the method comprising:

• receiving one or more first signals from one or more navigation satellites at a first antenna;
• receiving one or more second signals from the one or more navigation satellites at a second antenna, wherein the second antenna is separated from the first antenna by a first distance;
• receiving the one or more first signals at a first receiver coupled to the first antenna, wherein the first receiver is configured to extract a first carrier phase data from the one or more first signals;
• receiving the one or more second signals at a second receiver coupled to the second antenna, wherein the second receiver is configured to extract a second carrier phase data from the one or more second signals;
• determining a presence of a spoofed signal among the one or more first signals and the one or more second signals, wherein the presence is determined based on the first carrier phase data, the second carrier phase data, and the first distance between the first antenna and the second antenna.

A non-transitory computer readable storage medium storing one or more programs for detecting a spoofed signal, the spoofed signal comprising position-navigation-timing (PNT) data, for execution by one or more processors of an electronic device that when executed by the device, cause the device to:

• receive one or more first signals from one or more navigation satellites at a first antenna;
• receive one or more second signals from the one or more navigation satellites at a second antenna, wherein the second antenna is separated from the first antenna by a first distance;
• receive the one or more first signals at a first receiver coupled to the first antenna, wherein the first receiver is configured to extract a first carrier phase data from the one or more first signals;
• receive the one or more second signals at a second receiver coupled to the second antenna, wherein the second receiver is configured to extract a second carrier phase data from the one or more second signals;
• determine a presence of a spoofed signal among the one or more first signals and the one or more second signals, wherein the presence is determined based on the first carrier phase data, second carrier phase data, and the first distance between the first antenna and the second antenna.
