A system deploys electronic countermeasures against unmanned aerial vehicles (UAVs) that are determined to be a threat. A radio transceiver coupled to at least one antenna detects if radio signals are being communicated between a remote control unit and a UAV. A mitigation engine communicatively coupled to the radio transceiver synthesizes an exploit signal to be transmitted to the UAV, wherein the exploit signal is configured to inject commands into the UAV's navigation system. If the system determines that the UAV is operating in an autopilot mode, it transmits an induce-mode signal that causes the UAVs to switch to a communication mode so the UAV is responsive to the exploit signal.

Disclosed is a low-altitude unmanned aerial vehicle surveillance system. According to an embodiment, monitoring is performed using a balloon main body filled with gas and staying in the air; radar; camera units being provided outside the balloon main body, and including a camera taking an image of a subject; radio frequency detectors; and sound detectors and correspondingly, interceptor means is included. As interceptor means, a jammer, a jamming gun, and a spoofing device corresponding to jamming are disclosed.

A portable countermeasure device is provided comprising one or more directional antennae, one or more disruption components and at least one activator. The portable countermeasure device further comprises a body having a dual-grip configuration, with the directional antennae are affixed to a removable plate on a front portion of the body. The one or more disruption components may be internally mounted within the device body. The dual-grip configuration allows an operator to use his body to steady and support the device while maintaining the antenna on target. The second grip is positioned adjacent the first grip, with the first grip angled toward the rear of the device and the second grip angled toward the front of the device. The portable countermeasure device is aimed at a specific drone, the activator is engaged, and disruptive signals are directed toward the drone, disrupting the control, navigation, and other signals to and from the drone.

A method, a computer program, and a device for reducing interference of temporary communication resources used for a wireless communication between a transportation vehicle key and a transportation vehicle. The method includes determining whether interference of the temporary communication resources is present and switching off the device causing the interference or adjusting the use of the temporary communication resources for the wireless communication between the transportation vehicle key and the transportation vehicle in response to interference being present.

A portable countermeasure device is provided comprising one or more directional antennae, one or more disruption components and at least one activator. The portable countermeasure device further comprises a body, with the directional antennae are affixed to a front portion of the body. The one or more disruption components may be externally or internally mounted to the device body. The portable countermeasure device is aimed at a specific drone, the activator is engaged, and disruptive signals are directed toward the drone, disrupting the control, navigation, and other signals to and from the drone.

A privacy protection method and system (10) is provided for a building, home, apartment, or other area (12) protected by a connected security system (14). The system (10) includes a detector drone (16) and the security system (14). The drone (16) includes at least one drone detecting sensor (24) and automatically initiates a wireless signal (30) in response to the sensor (24) indicating the presence of a foreign drone (17). The security system (14) includes a central processor (40) and at least one electronic device (46) having a privacy condition wherein the device (46) protects against privacy intrusions by a foreign drone (17) and a non-privacy condition wherein the device (46) does not protect from the privacy intrusion. The processor (40) is configured to command the device (46) to change from the non-privacy condition to the privacy condition in response to the wireless signal (30) from the detector drone (16).

An RF antenna platform selectively configurable for portable or non-portable use, the platform comprising: a body comprising at least one RF antenna for transmitting and receiving RF signals; at least one component interface provided on the body for interchangeable mounting of different types of stabilising component to the body; wherein the component interface is common to each of the different types of stabilising component such that the portable and non-portable configurations of the platform are selectively determined by the type of stabilising component mounted to the body.

According to a first aspect of the present invention, there is provided a reconnaissance and communication assembly, adapted to be launched from a gun barrel into the air. The assembly comprises a carrier (with a cavity) and a payload (within the cavity). The payload is arranged to be controllably expelled from the carrier and once expelled from the carrier, the payload transmits a signal.
