Abstract: An acoustic air data sensing system includes an acoustic transmitter and a plurality of acoustic receivers. The acoustic transmitter is located to transmit an acoustic signal into airflow about an exterior of a vehicle. Each of the acoustic receivers is located at a respective angle from a wind angle reference line and a respective distance from the acoustic transmitter. Planar components of a velocity of the airflow are determined based on signal velocities of the acoustic signal to each of the plurality of acoustic receivers and the respective angles of the acoustic receivers from the wind angle reference line. Based on the planar components, the acoustic transmitter determines one or more of true airspeed and relative wind angle of the airflow about the exterior of the vehicle. The acoustic transmitter outputs the one or more of the true airspeed and the relative wind angle for operational control of the vehicle.

Abstract: An angle-of-attack sensor includes at least one acoustic transmitter is configured to provide an acoustic pulse. The first acoustic receiver is positioned at a radial distance from the at least one acoustic transmitter. The first acoustic receiver is configured to receive the acoustic pulse at a first time and provide a first receiver signal. The second acoustic receiver is positioned at the radial distance from the at least one acoustic transmitter aligned with an axis that extends through the at least one acoustic transmitter and the first acoustic receiver. The second acoustic receiver is configured to receive the acoustic pulse at a second time and provide a second receiver signal. The angle-of-attack circuitry is configured to determine a delay difference between the first and second receiver signals representative of a difference between the first time and the second time and determine an angle-of-attack based upon the delay difference.

Abstract: Apparatus and associated methods relate to controlling, based on a mode selector, the field of view of an external object detector during aircraft taxi operations. For example, during high-speed taxi operations, the field of view can be controlled to have a relatively-small solid-angle of detection capability. The relatively-small solid-angle field of view can be aligned so as to detect more distant objects within a narrow corridor extending forward of the aircraft's wingtips. During low-speed taxi operations, for example, the field of view can be controlled to have a relatively-large solid-angle of detection capability. The relatively-large solid-angle field of view can be aligned so as to detect close objects in the vicinity of the aircraft wings and engine nacelle. The object detector projects structured light within the controlled field of view, thereby illuminating the object(s) external to the aircraft that are within the illumination field of view.

Abstract: A system can include an unmanned aerial vehicle and an altimeter disposed on the unmanned aerial vehicle. The altimeter can include an ultra-wideband radar antenna disposed orthogonally to a plane of straight and level flight of the unmanned aerial vehicle and having an omnidirectional azimuthal beam pattern orthogonal to the plane of straight and level flight of the unmanned aerial vehicle. The altimeter can be configured to determine an altitude of the unmanned aerial vehicle above a target surface based on time of flight of radar pulses between the ultra-wideband radar antenna and the target surface.

Abstract: An air data computer configured to be installed on an aircraft includes an inertial sensor assembly having a plurality of accelerometers and a plurality of rate gyroscopes. The air data computer is configured to: determine a pressure altitude of the aircraft based on measured pressure of the airflow about the exterior of the aircraft; determine an estimated attitude of the aircraft based on rotational rate sensed by the plurality of rate gyroscopes; and determine a vertical acceleration of the aircraft based on the estimated attitude of the aircraft and the acceleration sensed by the plurality of accelerometers. The air data computer is further configured to blend the vertical acceleration and the pressure altitude using a complementary filter to produce a blended altitude rate that is output to consuming systems.

Abstract: Apparatus and associated methods relate to calculating position and/or range data of object(s) in a scene external to an aircraft. A light projector is configured to project, from an aircraft projector location, a collimated beam of light in a controllable direction onto the scene. The light projector is further configured to control the intensity of the projected light, based on the controlled direction of the collimated beam of light. The reflected beam is detected by a camera located apart from the light projector. An image processor is configured to use triangulation, to calculate position values and/or range data of the object(s) in the scene. The image processor can be further configured to identify the object(s) in the scene and to produce, based in object(s) in the scene, one or more maps of the scene. The intensity of the collimated beam can be controlled based on the produced maps.

Abstract: An imager device disposed on a moving body captures first image data at a first time and second image data at a second, subsequent time. An inertial measurement unit (IMU) disposed on the moving body senses motion of the moving body between the first time and the second time. The first image data is registered to the second image data based on inertial measurement data corresponding to the sensed motion to produce first registered image data. In response to identifying that image features are common to both the first registered image data and the second image data, the first registered image data is registered to the second image data based on the identified common features to produce output registered image data. In response to determining that no image features are common to both the first registered image data and the second image data, the first registered image data is output.

Abstract: Apparatus and associated methods relate to coordinating targeting among multiple guided ordnances using inter-ordnance optical communications. An inter-ordnance communications channel is optically established between leading and trailing guided ordnances travelling in substantially the same direction. The leading guided ordnance emits an optical beacon in a direction aft of the direction of ordnance travel, and a trailing guided ordnance captures images that contain the optical beacon emitted by the leading guided ordnance. The trailing guided ordnance is configured to chart a trajectory of the leading guided ordnance. The trailing guided ordnance is configured to predict which, among multiple targets identified in the captured images, is a first target consistent with the charted trajectory of and therefore selected by the leading ordnance. The trailing guided ordnance is further configured to select, based on the captured images, a second target that is within a navigable range of the trailing guided ordnance.
