Abstract: An aircraft communication system includes, and a method of aircraft communication uses, communication radios and a multilink communication controller. The multilink communication controller includes a link selection table and a link selector. The link selector is in communication with the link selection table. The link selector is configured to receive a message from a system of the aircraft and select a communication link among a number of communication links for the message using a priority of the message and priority information from the link selection table.

Abstract: An apparatus for forecasting weather related threats aboard an aircraft includes a computer for sending and receiving meteorological data to and from other aircraft in a self-organizing mesh network of aircraft. The computer isolates meteorological sensor data originating from the other aircraft in a region along the flight path of the aircraft and uses that data to forecast weather related threats along the aircraft's flight path.

Abstract: An aircraft remote network, device, and method are disclosed. The network may include a central data management unit (CDMU) and one or more aircraft systems, where each system may include an antenna and one or more units, through which radio frequency (RF) signals are transmitted and/or received. The device could receive a RF signal from an external source via the antenna, convert the signal to data, and provide the data to the CDMU; and receive data from the CDMU, convert the data to an RF signal, and provide the RF signal to the external source via the antenna, where the distance between the antenna and the device is less than the distance between the device and the CDMU.

Abstract: A very high frequency (VHF) transceiver can include an amplitude and phase shift keying (APSK) modulator configured to modulate signals for transmission across a first VHF channel of a plurality of VHF channels used to communicate between or among aircraft and one or more ground stations. Each of the VHF channels can have a bandwidth of at least 8.33 kilo Hertz (kHz) with a data rate per Hertz (Hz) greater than or equal to 3 bits per second per Hz (bps/Hz). The VHF transceiver can include a power amplifier configured to amplify the modulated signals prior to the transmission. The VHF transceiver can include a linearity controller configured to control linearity of the power amplifier according to at least one of a Cartesian feedback amplifier linearization, pre-distortion amplifier linearization or feedforward amplifier linearization to mitigate nonlinear distortion associated with signals output by the power amplifier.

Abstract: The present disclosure is directed to a system and method for determining an ownship position of an aircraft. The method includes the steps of receiving data from a plurality of proximate aircraft and examining the data. Next, the method involves selecting a plurality of reference aircraft from the plurality of proximate aircraft, and receiving data from each reference aircraft. The data received from the reference aircraft is then correlated to a common time in order to create a reference frame for calculating the position of the aircraft. The next step of the method is to calculate the ownship position of the aircraft based on the data received from the reference aircraft and the common time. The system includes a receiver, processor, display, and transmitter, which are used to determine the ownship position of an aircraft.

Abstract: A method and apparatus for establishing a high data rate high frequency data link (HDR-HFDL) between aircraft and ground stations enhances the aircraft HFDL data radio to transmit at an HDR frequency assigned by a ground station and transmitted to the aircraft via the HFDL frequency assigned to the ground station. The ground station may select and transmit an alternate HDR frequency if necessary. In Phase I, existing aircraft subsystems and ground stations will be configured for HDR downlink only, but an aircraft subsystem may additionally receive HDR data packets if propagation conditions allow. In Phase II, dedicated HDR ground stations and enhancements to existing aircraft subsystems will provide for full HDR uplink and downlink capability. Dedicated HDR ground stations may select an HDR frequency from the band including the assigned HFDL frequency or transmit at an assigned HDR frequency.

Abstract: A system for providing the capability for a vehicle to avoid regions of signal interference from high energy (HE) electromagnetic (EM) radiation emitters. The system includes a processing module. A database is operatively connected to the processing module. The database comprises a plurality of geographical areas affected by HE EM radiation emitters and data associated with the geographical areas. The data includes location, lateral and vertical extents, and signal attenuation for selected geographical areas affected by HE EM radiation emitters. The data preferably also includes affected frequency spectrum for the selected geographical areas. A display system is operatively connected to the processing module. The processing module functions to receive information regarding the position of the vehicle and query the database to retrieve relevant HE EM radiation emitters which are a threat to the vehicle's ability to properly navigate or communicate.

Abstract: A system may include a sensor for coupling with a vehicle configured for atmospheric flight. The sensor may be configured for detecting a turbulence event, where the turbulence event is at least one of experienced by the vehicle or occurs proximal to the vehicle during atmospheric flight. The system may also include a transmitter coupled with the sensor. The transmitter may be configured for automatically remotely transmitting data regarding the turbulence event to a ground based entity.

Abstract: An improved method and apparatus for drawing energy management circles on electronic flight instrument system displays which includes a microprocessor for making several initial inquiries regarding the orientation of the circle with respect to the display and issuing write or don't write commands for each point on the circle without the need for individually analyzing each point as to whether it is located on the display screen.
