Abstract: A method, system and product for identifying spoofed maritime signals based on receiving reception stations. The method comprises obtaining one or more location-reporting signals of a maritime vessel, wherein the one or more location-reporting signals comprise one or more respective sets of geographical coordinates, each of which having a timestamp. The method further comprises determining that the one or more location-reporting signals are at least partially fabricated. The determination comprises: identifying a station that received the one or more location-reporting signals, wherein the station having a reception polygon; and determining that at least one set of geographical coordinates indicated by the one or more location-reporting signals is fabricated based on the reception polygon of the station. The method further comprises performing a responsive action.

Abstract: A peak suppression monitor is coupled to a tracking channel. The peak suppression monitor facilitates receiving, from the tracking channel over a time period, real-time correlation data derived from a global navigation satellite system signal. The real-time correlation data having one or more peaks. Predicted correlation data corresponding to the real-time correlation data is determined based on historical correlation data. A presence of spoofing within the real-time correlation data is identified based on one or more peaks of residual correlation data. The residual correlation data including a comparison between the real-time correlation data and the predicted correlation data. Spoofing detecting data is generated based on the presence of spoofing and the residual correlation data. The generated spoofing detecting data to the tracking channel is provided for further mitigation or a notification identifying the presence of spoofing is provided to a user.

Abstract: A method for sensor operation includes deploying a network of sensors, which have respective clocks that are not mutually synchronized. At least a group of the sensors receive respective signals emitted from each of a plurality of sources, and record respective times of arrival of the signals at the sensors according to the respective clocks. Location information is provided, including respective sensor locations of the sensors. The respective clocks are synchronized based on the recorded times of arrival and on the location information. In the process the sources may be localized, or if the sources are far away, then their directions may be resolved. Sensor positions may also be resolved in the process.

Abstract: A system for accurate geospatial location and time transfer using radio transmissions without satellite signals. A position and timing measurement system uses standard uncorrelated radio broadcast signals, each of which transmits on an assigned frequency from a known position defined in latitude and longitude, and each of which transmits a modulated or unmodulated carrier signal. A reference unit at known fixed position receives the said standard broadcast signals in the vicinity, samples the frequencies and content values of their signals and broadcasts the said measured frequency and content data nearly simultaneously with a time mark representing the time of said measurement and further broadcasts its position in latitude and longitude. A mobile unit at an unknown position to be determined receives the said standard broadcast signals in the vicinity and measures the time of arrival of their broadcast, recording the time of said measurement.

Abstract: Disclosed herein are system, method, and computer program product embodiments for adapting to malware activity on a compromised computer system by detecting timing anomalies between timing signals. An embodiment operates by analyzing first timing data accessed from a validated source and second timing data accessed from an unvalidated receiver source in order to compute a threat detection value, which is utilized to determine if there is a discrepancy or anomaly in the timing or frequency of either the validated and unvalidated sources.

Abstract: In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.

Abstract: A method can include and/or a system can be configured for determining satellite positioning corrections, generating a satellite positioning corrections message to transmit the satellite positioning corrections to an endpoint. The method can optionally include and/or the system can optionally be configured for establishing or determining a chain-of-trust, validating the satellite positioning corrections (e.g., at the endpoint), and/or determining a positioning solution.
