Abstract: A radio frequency (RF) front-end module (FEM) includes an amplifier and an integrated circuit coupled to the amplifier. The integrated circuit includes a buffer amplifier coupled to the amplifier, a variable attenuator coupled to the buffer amplifier, a phase shifter or time delayer coupled to the buffer amplifier, and a memory configured to store a gain calibration value and a phase calibration value. The gain calibration value controls an attenuation of the variable attenuator and the phase calibration value controls a phase shift of the phase shifter or a time delay of the first time delayer. The RF FEM also includes an interface configured to store the gain calibration value and the phase calibration value in the memory, an RF connection to a transceiver, and an RF connection to an antenna.

Abstract: An active electronic steered antenna (AESA) circuit monitors bursts of a phased array that has a plurality of signal chains. Each signal chain therefore has a burst output for transmitting at least one burst. To monitor bursts, the AESA circuit has an input that is operably couplable with the burst output of at least one signal chain of the phased array. The input is configured to receive one or more bursts transmitted by the burst output(s) of the at least one signal chain. The AESA circuit also has a sample circuit operably coupled with the input and configured to sample the one or more bursts to produce one or more corresponding samples, and memory operably coupled with the sample circuit. The memory receives and stores the one or more samples. To provide access to the samples, the AESA circuit also has a memory interface.

Abstract: Systems and methods for trusted mobile communications are described. A network system provisions a mobile client system with a collection of security parameters on a per application basis and a per device basis. The airplane system provides access to the mobile client system based on the established chain of trust without previously having information about the mobile client system even when the mobile client system and the airplane system are offline with respect to the network system.

Abstract: Methods, apparatuses, computer program products, and computer readable media are disclosed herein. In one aspect, an apparatus can include a transmission line configured to accept a radio frequency signal from an antenna, wherein the antenna is configured to receive the radio frequency signal from a satellite. The apparatus can further include a system on a chip comprising a direct conversion receiver, a digital signal processor configured to process a digital representation of a baseband receive waveform to determine received information, and a wireless networking interface configured to send the received information to a satellite communications indoor unit.

Abstract: A method of coordinating communications between a plurality of Unmanned Air Vehicles (UAVs) operating in connection with differing communication languages. A common language is provided which includes common language commands and common language data objects. Common language commands are communicated from a user to a plurality of UAVs through a UAV Interoperability Agent (UIA), which converts the common language commands to UAV-specific commands which can be understood by the specific UAV. Additionally, UAVs send data in a native platform format to the UIA, which converts the native platform data to common language format for collection and interpretation by the user.

Abstract: Embodiments of a sensor network system provide surveillance capabilities in multiple contexts/environments (e.g., military, commercial, scientific, civic, urban, wilderness, etc.). Network nodes may include devices such as sensors, network routers, network controllers, etc. Network sensors may be configured so that power management objectives are maximized. Network sensors (both individually and as a group) may be capable of intelligent and cooperative information gathering, so that the output of the sensor network does not contain high levels of irrelevant information. The network nodes may communicate among one another via one or more communication links, and in some cases, multiple routes between any two network nodes may be available. The sensor network may include aspects of both high data rate and low data rate network features.

Abstract: A method and system are provided for executing a protocol for tunneling of transmission control protocol/internet protocol (TCP/IP) packets over a tactical link. The tunneling protocol includes interfacing to a host software on a node of a tactical network using a TAP interface; breaking up ethernet packets from the TAP interface into J16.0 messages that include payload data from the ethernet packet and header information that uniquely identifies the J16.0 message for deterministic reassembly of the ethernet packet from the stream of J16.0 messages in which it is included. The J16.0 messages may be transmitted using a fighter data link over a tactical network link. At the destination node of the link, the J16.0 messages may be reassembled into ethernet packets, allowing the tactical network to be implemented as virtual private network having (internet protocol) IP addresses for each node.

Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide a first data processing system access to a network via a second data processing system. An object is sent to the second data processing system, which object when instantiated on the second data processing system implements a network access program that can subscribe to information from the network and publish information to the network. Subscribed to information is received from the second data processing system.
