Disclosed are methods, systems, and non-transitory computer-readable medium for managing energy use in a vehicle. For instance, the method may include receiving forecasted data from a first external source, receiving real-time data corresponding to at least one weather parameter at a first location at a first time, and continuously determining whether to perform an adjustment to a control parameter of the vehicle by using a machine learning model that is based on the forecasted data for the at least one weather parameter, the real-time data for the at least one weather parameter, a battery condition of the vehicle, and/or an estimated amount of energy consumed by traveling along a first navigation path.

A system, apparatus, and related method for receiving and correlating Manchester encoded data signals includes a receiver for receiving 1090ES/ADS-B or other Manchester encoded signals. A sampler extracts and oversamples data strings from the received signals. Sample correlators compare the oversampled data strings to oversampled versions of each possible pattern for the extracted data string and determine a score indicating how closely the possible pattern (or its oversampled counterpart) matches the extracted data string (or its oversampled version) on a bitwise or symbolwise basis. The system outputs correlated and decoded data string most closely matching the extracted data string based on the set of determined scores.

An integrated, externally-mounted Automated Dependent Surveillance-Broadcast (ADS-B) device comprising in one embodiment a 1030 MHz transmitter, a 1030 MHz antenna, a 1090 MHz receiver, a 1090 MHz antenna, a GNSS receiver, at least one GNSS antenna, a 978 MHz transmitter, and a 978 MHz antenna, wherein these components are integrated into a single enclosure, and wherein the GNSS antenna is placed at least partially into a projection extending out from the main enclosure body, such that the GNSS antenna has improved visibility to GNSS signals originating from altitudes above the current altitude of aircraft when the ADS-B device is mounted on the bottom of an aircraft.

Various avionics systems may be enhanced by methods and systems for bearing reception. For example, a traffic alert and collision avoidance system, or other surveillance system, can be provided with a system or configured for a method of improved bearing reception. For example, a method can include performing traffic alert and collision avoidance surveillance of a target aircraft using an interrogation over a bottom antenna of an own aircraft. The method can also include enhancing determination of a bearing of the surveillance by obtaining a bearing of the target aircraft using an alternative to making a bearing determination based on signal characteristics of a reply to the interrogation.

A detect-and-avoid system for an ownship aircraft is disclosed. The system has a control station in communication with an ownship aircraft, and a Passive Secondary Surveillance Radar (PSSR) system at the ownship aircraft. The PSSR is equipped to receive a reply from a target object, in response to an interrogation signal of staggered P1 and P3 pulses sent by a narrow-beam antenna of a Secondary Surveillance Radar (SSR) to the target object, and also to receive P2 pulses transmitted by a wide-beam antenna of the SSR. A pulse repetition frequency (PRF) pattern for the staggered interrogation signal is determined, followed by estimating a transmit time of the interrogation signal, and determining a position of the target object. A corresponding detect-and-avoid method is also disclosed.

A method and system for downloading aeronautical data using an automatic dependent surveillance-broadcast (ADS-B) is provided. The method comprises creating a first data sequence structure that includes a receive time for each of one or more received ADS-B messages; creating a second data sequence structure that includes a packet time for each of one or more received aeronautical data packets that are without position information; mapping the received aeronautical data packets respectively to the ADS-B messages by comparing the receive time for each of the received ADS-B messages with the packet time for each of the received aeronautical data packets to produce a correlation between the ADS-B messages and the aeronautical data packets; and deriving position information for each of the received aeronautical data packets from each correlation between an ADS-B message and an aeronautical data packet.

The invention refers to a secondary surveillance radar, referred to hereinafter as SSR, system (1) for air traffic control. The SSR-system (1) comprises a plurality of secondary radar stations (2) and is adapted for determining a location of an air traffic vehicle within the range of coverage of at least some of the secondary radar stations (2) by means of propagation time measurement of data signals (8) transmitted between the secondary radar stations (2) and a transponder (9) of the air traffic vehicle. Each of the secondary radar stations (2) works on a synchronized local time base. In order to provide for a high-precision synchronisation of the radar stations (2) of the SSR system (1) free of clusters, it is suggested that an SSR system's (1) secondary radar station (2) is synchronized depending on the content of synchronisation signals (10) received by the secondary radar station (2) to be synchronized and broadcast by one of the other secondary radar stations (2) of the SSR system (1). Preferably, the content comprises a time of transmission of the synchronisation signal (10).

Systems and methods relating to the use of one type of radar technology to accomplish the function of another type of radar technology. Secondary Surveillance Radar/Identification Friend or Foe (SSR/IFF) technology can be used as if it was Primary Surveillance Radar (PSR) to gain the advantages of both systems. Radar signals useful for SSR/IFF are used as PSR signals. Reflections of the SSR/IFF signal off of both airborne and ground based aircraft, and ground based vehicles and items are used to locate and identify these aircraft, vehicles and items. For SSR/IFF transponder equipped aircraft, the reflected SSR/IFF signals provide (prove dial) dual confirmation of the aircraft's presence while for non-transponder equipped aircraft, the reflected signals provide an indication of the aircraft's presence. The use of SSR/IFF signals reflected off of ground based vehicles and items provides an indication of ground based vehicles and items present around the installation receiving the reflected SSR/IFF signals.

Systems and methods relating to air traffic control and navigational aids for aircraft. An antenna system uses a multi-sector sensor that uses two vertical column antenna arrays per sector. Each pair of vertical column antenna arrays produces two beams that are off a boresight for each pair of antenna arrays. Wide angle monopulse processing is used to determine an azimuth or angle of arrival for an aircraft using at least one pair of the vertical column antenna arrays. Predetermined correction factors are applied to the azimuth for specific elevation values and, for elevation values without predetermined correction factors, interpolation between known predetermined correction values to arrive at the corrector factor to be applied.
