Systems and methods are provided for weapon systems monitoring and remote support, including application software that receives signals from a plurality of weapons, each weapon including a plurality of sensor types. A connection point may receive signals from the weapons within a deployment location, including sensor information recorded using sensors associated with the weapons and video from at least one camera. The application software may receive the signals from the connection point and process the signals to generate a graphical user interface representing positions and orientations of the weapons within the deployment location, the graphical user interface further presenting video of areas in proximity to each of the firearms, where the application software automatically updates the graphical user interface based on signals indicating changes in the positions and orientations of one or more of the weapons and related video content.

Systems and methods are provided for monitoring a state of ammunition supply among a plurality of firearms within a deployment location, where each firearm includes one or more sensors that record sensor information used to produce a signal. A response infrastructure may be configured for deployment to the deployment location, and a server device running application software that uses the signals received from each of the firearms may detect an ammunition level of a firearm within the deployment location and cause the deployment of the response infrastructure to the deployment location, where the response infrastructure supports a resupply of at least one firearm in the deployment location.

A method for facilitating real time tracking of an airborne asset via downlink of GPS signals that are usable for determining asset location information from the asset to a ground station may include receiving a first GPS signal and a second GPS signal at a device disposed on the airborne asset and combining the first and second GPS signals to form combined signal responsive to filtration and amplification of the first and second GPS signals. The method may further include employing an overlay analog translation to convert the combined signal into a composite signal at a different frequency than the combined signal, generating a pilot carrier frequency for association with the composite signal, and amplifying the composite signal prior to transmission via the downlink from the airborne asset to the ground station. The pilot carrier frequency and amplitude may be adjustable.

A method of synchronizing flashing between a plurality of marker system components mounted on a helmet includes receiving a signal from at least one global positioning satellite receiver, the signal comprising a time value. When the time value indicates illumination is needed, initiating illumination of at least one light emitting device of each the marker system components, thereby, synchronizing of the initiating of illumination to the time value for all marker system components.

A system for determining a location in a disadvantaged signal environment includes three aerial vehicles hovering at high altitude and spaced apart to form a triangle, and a mother aerial vehicle positioned a distance away and at a lower altitude. The mother aerial vehicle acquires and transmits coarse geolocation information, using a pulse compression, high-power X Band radar and directional antenna, to each of the three aerial vehicles to direct them to coarse geo-positions above designated respective ground locations. One of the three aerial vehicles has a synthetic aperture radar for producing a terrain strip-map that is mensurated against a map database to provide fine position adjustments for each of the three aerial vehicles, which are also also configured to transmit a respective signal coded with its latitude, longitude, and altitude, for a computing device to perform time difference of arrival measurements of the signals to determine its location.

System and method for concurrently protecting Iridium and GPS L1/L2 band received satellite signals against interference signals (e.g., jamming signals) using space-time adaptive processing (STAP). While the GPS signal is protected against jamming using Nulling of the interfering signals, the Iridium signal is protected using Beamforming. A single broadband small controlled reception pattern antenna (sCRP) array receives both the GPS (L1 and L2) and Iridium signals for the STAP-based antijam solutions outputting filtered Iridium and GPS signals. Use of a common (small) broadband antenna and common front end signal processing of the received signals enables an integrated system for use on size, weight, and power constrained platforms such as drones, unmanned aerial vehicles (UAVs), and helicopters.

Apparatus and methods determine the rotational position of a spinning object. A satellite positioning system can be used to determine the spatial position of an object, which in turn can be used to guide the object. An adaptive sideband filter is used to provide increased robustness against interference. However, when the object is spinning, such as an artillery shell, then the rotational orientation should be known in order to properly actuate the control surfaces, such as fins, which will also be spinning.

An apparatus and method are described for processing a global navigation satellite system (GNSS) signal, the GNSS comprising multiple satellites, wherein each satellite transmits a respective navigation signal containing a spreading code. The method comprises receiving an incoming signal at a receiver, wherein the incoming signal may contain navigation signals from one or more satellites; encrypting the incoming signal at the receiver using a homomorphic encryption scheme to form an encrypted signal; and transmitting the encrypted signal from the receiver to a remote server.

A weapon training system including a magnetic sensor system is described. The magnetic sensor system is insertable into or integrated with a round of an indirect firing weapon and includes at least one magnetic sensor and a microcontroller communicatively coupled to the at least one magnetic sensor. The microcontroller is configured to perform operations including receiving at least one proximity signal from the at least one magnetic sensor indicating a proximity of at least one magnet of at least one charge to the at least one magnetic sensor, determining, based on the at least one proximity signal, that the at least one charge is removably attached to the round, generating an output signal indicating that the at least one charge is removably attached to the round, and wirelessly transmitting the output signal to an electronic device.
