The collision avoidance system includes a data input module configured to obtain object data and contextual data from a plurality of aircraft systems. The collision avoidance system further includes a processor configured to combine the object data into an aggregated list of detected objects, and label the aggregated list of detected objects using the contextual data to form a contextualised list of detected objects for use in determining collision avoidance. The collision avoidance system further includes a data output module configured to output the contextualised list of detected objects to a set of output systems.
An aircraft-based system for providing forward-looking terrain profiling and downward-looking altimetry via a single active electronically scanned array (AESA) orients the AESA through a sequence of desired directions, e.g., according to a predetermined scan pattern. At each desired direction, the AESA scans for ground-based targets, determining a range and Doppler velocity to each detected target. The AESA additionally orients downward, e.g., during a dedicated altimetry frame and with the assistance of inertial sensors to determine the orientation of the AESA, to scan terrain directly below the aircraft and provide a precise estimate of the altitude of the aircraft. Based on the determined ranges and velocities, the radar system determines a pointing angle and vertical/horizontal distances between the aircraft and each identified ground-based target.

An ESA includes radiating elements having a normal mode radiating element and a superimposed end-fire mode radiating element. The combined normal mode radiating element and and-fire mode radiating element attenuators or variable gain amplifiers for amplitude adjustment, phase shifting, and time delay circuitry and algorithms to drive the normal mode radiating element and end-fire mode radiating element simultaneously to produce radiation patterns that constructively interfere. Alternatively, the radiating elements are fed by a radio frequency (RF) feed and switching integrated circuitry timed to drive the normal mode radiating element and end-fire mode radiating element to effectively produce hemispherical radiation patterns as a function or time/scan angle.

A computer implemented method for detecting timing faults during execution of a task having an estimated worst case execution time (WCET). The method includes, in response to a monitoring interrupt occurring, determining the progress of the task at the interrupt and the executed time of the task up until the interrupt, determining the remaining worst case execution time (rWCET) for the task to finish its execution from the progress of the task at the point of interrupt, and if the sum of the rWCET and the run time of the task exceed the estimated WCET of the task, then detecting that a timing fault will occur.
Neutron single effect events are mitigated using gadolinium. Layers of gadolinium are fully encapsulated as part of an airborne electronic hardware, in circuit boards, in heat sinks, and as part of the device packaging. The gadolinium layers are designed to shield semiconductor chips from neutrons. Shielding the semiconductor chips from the neutrons reduces the upset rate of device packages using the semiconductor ships.

An HF mesh network node includes an Electric Field Rydberg sensor as a compact broadband HF antenna. The Electric Field Rydberg sensor ensures that the receiver has visibility of a large band of HF spectrum and can therefore receive all propagating frequencies in that band simultaneously. The system may receive control information via the Rydberg sensor to establish a direct connection with a distant node via a traditional coupler and antenna on a specific frequency. The system may include a plurality of Rydberg sensors, each specifically tuned to cover a 10 MHz range of an extended spectrum.
A system and method for validating navigational aids includes a navigation solution monitor that receives sensor inputs from a plurality of onboard sensors and produces a trustworthiness metric. The navigation solution monitor updates inertial navigation units (INU) based on the sensor with the highest trustworthiness metric. The navigation solution monitor may measure the trustworthiness of each sensor against every other sensor such that the trustworthiness metric represents a deviation from other sensors.

An aircraft radar system includes an antenna, a processor, and a data storage element. The data storage element includes geolocation data of ground-based structures that are likely to produce ground clutter. Based on the location and orientation of the aircraft, the processor determines where to produce a null in the antenna beam to exclude the ground clutter. Sensors on the aircraft provide data to geolocate ground clutter inducing targets in real-time. Sensor data is collated, and potentially correlated to stored maps or other databases. A trained machine learning algorithm may receive sensor data and other inputs to identify ground clutter inducing targets, and potentially generate nulls to exclude such targets.
