An interference detector for detecting interference in Global Navigation Satellite System (GNSS) includes an RF splitter, multiple detectors and a comparator. RF splitter, splits a radio frequency (RF) input signal into multiple RF output signals which are provided to respective detectors. Each of the detectors includes a bandpass filter and a peak detector. The bandpass filter filters the RF output signal into a respective GNSS frequency band and the peak detector detects the peak level of the filtered RF signal. The comparator analyzes the peak detector outputs and identifies whether interference is present in the GNSS frequency bands by comparing the peak levels to respective thresholds. Based on this analysis, the comparator outputs a signal that indicates the presence and absence of identified interference in the GNSS frequency bands.

Systems, methods, and apparatus for identifying, tracking, and disrupting UAVs are described herein. A tracking system can include one or more first computing devices that receive sensor data associated with an object in a particular airspace from one or more sensors. The first computing device can analyze the sensor data relating to the object to determine information about the object. A portable countermeasure device can include one or more second computing devices. The second computing device can receive the information relating to the object. The second computing device can display a visual indicator indicating the information on a display.

Systems and methods are described for a cyber-physical vehicle management system generated by an Integrated Secure Device Manager (ISDM) Authority configured to manage licensing and approval of Cyber-Physical Vehicle (CPV)s, a public/private key pair and a unique ID for the Authority, create a self-signed Authority token signed by the private key, send the Authority token to a plurality of ISDM Node device configured to verify Module device authenticity and in communication with the Authority, store, by each Node, the Authority token, and mark, by each Node, the Authority token as trusted.

A radio frequency (RF) jamming device includes a differential segmented aperture (DSA), a jammer source outputting a jamming signal at one or more frequencies or frequency bands to be jammed, and RF electronics that amplify and feed the jamming signal to the DSA so as to emit a jamming beam. The DSA includes an array of electrically conductive tapered projections, and the RF electronics comprise power splitters configured to split the jamming signal to aperture pixels of the DSA. The aperture pixels comprise pairs of electrically conductive tapered projections of the array of electrically conductive tapered projections. The RF electronics further comprise pixel power amplifiers, each connected to amplify the jamming signal fed to a single corresponding aperture pixel of the DSA. The RF jamming device may include a rifle-shaped housing, with the DSA mounted at a distal end of the barrel of the rifle-shaped housing.

Techniques for determining whether data associated with an autonomous operation of a first unmanned vehicle may be trusted. For example, the first unmanned vehicle may receive an indication related to the data and originating from a second unmanned vehicle over a network. For instance, the indication may indicate that similar data for a similar autonomous operation of the second unmanned vehicle may be untrusted. Based on a level of trust accorded to the indication, the first unmanned vehicle may determine that the data may be untrusted and the autonomous navigation may be directed independently of the data.

A method and apparatus for providing a standalone anti-jamming (AJ) nuller-beamformer. Signals from an antenna array include a sum of Global Navigation Satellite System (GNSS) signals and jamming signals from a plurality of spatial sources. A front end is configured to amplify, filter, down-convert, and sample the input signals which are then filtered, downconverted, and decimated prior to frequency-domain and time-domain partitioning. Weights are computed and applied for spatial nulling of jamming signals in each frequency bin for the partitioned signals. Frequency and time-domain reconstruction generates a reconstructed signal with suppressed jamming.

Systems and methods for preventing flight of one or more Unmanned Aerial Vehicles (UAVs) in no-fly zones include receiving one or more no-fly zones each defined as geo-fences with associated coordinates; preventing one or more UAVs from entering the one or more no-fly zones by one or more of: transmitting the geo-fences to the one or more UAVs, transmitting avoidance commands to the one or more UAVs from an avoidance device located at a no-fly zone, and disrupting radio communication to the one or more UAVs from the avoidance device.

A portable Electromagnetic Countermeasure (ECM) device is disclosed for military and civilian population protection from electromagnetic communications and attack, including cell phones, radios, radio-triggered explosive devices, and other personal and portable devices comprising transmitters and receivers. The portable ECM device is usable by a person such as a soldier or policeman to protect themselves and other people around them from spy, guerrilla, military and terrorist threats. The portable (ECM) device comprises a first antenna and a second antenna, both to communicate radio signals with a software defined radio (SDR), and a control pack having a microprocessor operable by remote network connection, or by a mode selector on board the device, to control the SDR according to a mode selected, to receive, produce, and classify radio signals.

A system for disrupting Radio Frequency communication of a plurality of unmanned aircraft. The system comprises: a directional antenna; a transmitter; a drive system connected to the directional antenna and configured to move the directional antenna; and a control system. The control system causes the transmitter to generate a signal waveform configured to disrupt Radio Frequency communication of an unmanned aircraft for emission by the directional antenna, and causes the drive system to move the directional antenna such that each of the plurality of unmanned aircraft is irradiated intermittently by the emitted radiation. Each of the plurality of unmanned aircraft is irradiated for a first period of time and not irradiated for a second period of time, the second period of time is less than or equal to 5 seconds.

The invention concerns a vehicle tracking network including a plurality of subscriber vehicles and a control-center; and systems and methods for tracking vehicles, which are subscribers to such vehicle tracking network. In certain implementations, the method for tracking a subscriber vehicle includes the following operations carried out at the subscriber vehicle: monitoring operation of one or more services related to at least one of a wireless network communication service and positioning service associated with the subscriber vehicle; upon detecting a failure in at least one of said services, generating a corresponding distress signal encoded to be identifiable by other subscriber vehicle(s) of the vehicle tracking network; and broadcasting the encoded distress signal such that it is detectable by one or more of the other subscriber vehicles of the vehicle tracking network, which are located in the vicinity of the subscriber vehicle broadcasting the distress signal. Another subscriber vehicle(s), which receive the distress signal, may thereby initiate automatic notification of the condition of the vehicle broadcasting the distress signal to the control center.
