Global navigation satellite system interference attack detection

An apparatus for a spoofing source directed at interfering with satellite signaling from a satellite, comprising:

• a processor;
• and
• a memory including processor-executable instructions stored thereon, the processor-executable instructions upon execution by the processor configures the processor to:
• receiving a first set of information from a first communication node in a communication network indicating a first estimated location of the spoofing source;
• receiving a second set of information from a second communication node in the communication network indicating a second estimated location of the spoofing source;
• receiving a third set of information from a third communication node in the communication network indicating a third estimated location of the spoofing source;
• and
• determining a final location of the spoofing source based on triangulating the first, second, and third estimated locations of the spoofing source.

A computer-implemented method for detecting a signal directed at interfering with satellite signaling, the method comprising:

• receiving, by a receiving node, a signal from a signal source, wherein the signal produced by the signal source is disguised as a satellite signal;
• determining, by the receiving node, an estimated position of the receiving node based on an orbital position of the satellite and a characteristic of the signal;
• comparing, by the receiving node, the estimated position of the receiving node with a reference position of the receiving node;
• determining, by the receiving node, that the signal source is a spoofing source different than the satellite;
• and
• determining, by the receiving node, a location of the spoofing source in part based on the estimated position.

A computer-implemented method for determining a location of a spoofing source, comprising:

• receiving, by a network node in the communication network, a first set of information from a first communication node indicating a first estimated location of the spoofing source;
• receiving, by a network node, a second set of information from a second communication node indicating a second estimated location of the spoofing source;
• receiving, by a network node, a third set of information from a third communication node indicating a third estimated location of the spoofing source;
• and
• determining, by the network node, a final location of the spoofing source based on triangulating the first, the second, and the third estimated locations of the spoofing source.
