1 US2020104609A1
Pseudo-Range Estimation From A Passive Sensor
Publication/Patent Number: US2020104609A1 Publication Date: 2020-04-02 Application Number: 16/143,866 Filing Date: 2018-09-27 Inventor: Clothier, Reece Alexander   Williams brendan patrick   Hegarty-cremer, Solene Gabrielle Doreen   Assignee: The Boeing Company   IPC: G06K9/00 Abstract: A rough initial estimate of Line of Sight range (“pseudo-range”) is generated essentially immediately following the detection of an object by a passive sensor on a vehicle. The data are combined with prior detection likelihood and prior performance models for the sensor. These comparisons generate a posterior probability distribution of pseudo-range estimates. A pseudo-range estimate is derived from the probability distribution and output for use in detect and avoid decision-making and action planning. The pseudo-range estimate can be updated to improve its accuracy, such as by using a recursive filter (e.g., a Kalman filter). Other information, such as current atmospheric data, or known (or likely) vehicular activity in the region and at the current time, can be used in addition to the vehicle's spatial and temporal location, to improve accuracy.

AIRCRAFT FLIGHT INFORMATION SYSTEM AND METHOD
Publication/Patent Number: EP3633652A1 Publication Date: 2020-04-08 Application Number: 19201417.3 Filing Date: 2019-10-04 Inventor: Garden, Grace Shanti   Mecklem, Sarah Anne   Clothier, Reece A   Williams brendan patrick   Fulton, Neale Leslie   Assignee: The Boeing Company   IPC: G08G5/00 Abstract: A method includes determining data indicating velocity uncertainty, relative position uncertainty, or both, associated with an aircraft and a navigation hazard. The method also includes determining a set of bounding vectors based on the data and determining a plurality of candidate intersection points that together correspond to circular or spherical regions defined by the set of bounding vectors. The method also includes identifying a region of interest based on a projected intersection of the aircraft or the navigation hazard with a candidate intersection point and generating a situational awareness display based on the region of interest.

PSEUDO-RANGE ESTIMATION FROM A PASSIVE SENSOR
Publication/Patent Number: EP3629234A1 Publication Date: 2020-04-01 Application Number: 19199796.4 Filing Date: 2019-09-26 Inventor: Clothier, Reece Alexander   Williams brendan patrick   Hegarty-cremer, Solene Gabrielle Doreen   Assignee: The Boeing Company   IPC: G06K9/00 Abstract: A rough initial estimate of Line of Sight range ("pseudo-range") is generated essentially immediately following the detection of an object by a passive sensor on a vehicle.

AIRCRAFT DETECT AND AVOID GAUGE
Publication/Patent Number: US2020202732A1 Publication Date: 2020-06-25 Application Number: 16/792,403 Filing Date: 2020-02-17 Inventor: Mecklem, Sarah Anne   Williams brendan patrick   Davidson, Darcy Lynn   Benton, John W.   Cork, Lennon Richard   Popenoe, Peter Barton   Assignee: The Boeing Company   IPC: G08G5/04 Abstract: A method of generating an aircraft display includes receiving data at a device. The data includes information associated with a first aircraft and one or more other aircraft in an airspace associated with the first aircraft. The method includes determining, at the device, estimated flightpaths for the first aircraft and the one or more other aircraft. The method includes generating, at the device, a detect and avoid gauge display based on a current flightpath of the first aircraft and the estimated flightpaths. The method also includes sending, from the device to a display device coupled to the device, the detect and avoid gauge for display. The detect and avoid gauge is configured to display a flightpath indicator to indicate a direction of travel of the first aircraft and is configured to display alert bands related to projected separation violations with respect to the one or more other aircraft.
