Abstract: A system for mid-fidelity simulation may include a memory configured to store data representing a flight scenario. The system may further include a display device configured to present a graphical user interface to a user, the graphical user interface including representations of a first set of control interfaces, the first set of control interfaces including one or more features that are common between multiple aircraft, the graphical user interface omitting one or more features of the first set of control interfaces that are not common between the multiple aircraft. The system may also include a processor configured to perform a simulation of the flight scenario while receiving user input and displaying user output via the representations of the first set of control interfaces.

Abstract: A system and method for verifying ADS-B messages received at an aircraft from other aircraft within its ADS-B range. This disclosure enhances the current Automatic Dependent Surveillance-Broadcast (ADS-B) IN surveillance systems, and the disclosed system is an onboard system designed to enable ADS-B IN capable aircraft to verify the information received via ADS-B from the rest of the aircraft within its ADS-B range. The system's performance is based on the principles of multilateration (MLAT). The system performs MLAT calculations to determine whether the ADS-B messages received are truthful or not truthful. The disclosed system relies on a communication protocol based on a series of requests and responses to interchange the information needed by the aircraft involved in the process to carry out the MLAT calculations.

Abstract: Described are systems and methods of aircraft surveillance and tracking. A method for aircraft tracking includes partitioning an airspace region into multiple sectors and generating multiple data structures corresponding respectively to each of the multiple sectors. Each data structure has a primary identifier and at least one secondary identifier that matches the primary identifier corresponding to the at least one other sector. The method includes receiving at least one data packet from an aircraft located within one of the multiple sectors, storing the aircraft data from the data packet within the data structure corresponding to the one of the sectors, storing the aircraft data within each of the data structures that has a secondary identifier matching the primary identifier, and for each of the multiple sectors, sending each aircraft within the sector aircraft data stored within the data structure corresponding to the sector.

Abstract: A device and a method for monitoring continuously the activity of a microphone and a speaker of an electronic communications device, filtering any emitted or received signal in the ultrasound frequency spectrum (signals ?17 kHz) and assessing whether the emitted or received signal is malicious or benign, in order to detect and avoid malicious transmissions established on the ultrasounds frequency spectrum. If a malicious transmission is detected, the user is alerted and can allow or deny said transmission. The device and method are a new concept of Information Technology defense systems that complements traditional antivirus.

Abstract: Mobile multilateration systems and related methods are disclosed. An example method includes accessing multilateration data relating to a first aircraft using a time-difference-of-arrival determiner of a second aircraft; processing the multilateration data at the second aircraft to determine a calculated position of the first aircraft; comparing the calculated position of the first aircraft to an asserted position of the first aircraft stored at the second aircraft; and in response to the comparison, determining if the calculated position and the asserted position are within a threshold of one another using the time-difference-of-arrival determiner of the second aircraft to determine an authenticity of the first aircraft.
