Abstract: A training data management method and related system is disclosed comprising three integrated elements. A training data network may provide a network linking a remote instructor operating an off-board data network with a student operating an onboard data network. The remote instructor may, via the datalink connection, maintain a level of control of the data set available to the student. A method for providing training data may include an onboard and off-board safety monitor configured for perceiving a safety event and sending a notification thereof to an involved participant. A system for providing training data may include a data guard configured to monitor all communications between two networks and block sensitive information, training data, and classified communications between the networks.

Abstract: A method and system are disclosed for stereoscopic three dimensional (S3D) display of synthetic environment (SE) data simultaneously with operational symbology data to the operator of a vehicle. The method receives a plurality of data objects and places the objects within a plurality of levels of a presentation hierarchy and further within a plurality of S3D depth layers based on a set of data and operator focused rules. The method simultaneously displays to the operator each of the plurality of objects in the plurality of S3D depth layers according to the placement. The method transitions an object from one depth layer to a more proximal or distal depth layer to indicate relative motion or urgency. The method reserves a depth layer most proximal to the operator for a warning while a most distal set of depth layers is reserved for SE objects.

Abstract: A system and method is disclosed for correlation of received objects offering a valid presentation to an operator. The method correlates actual objects and simulated objects to offer a valuable training presentation environment to an operator. The method may receive a plurality of data streams including sensed data, simulated sensed data, and truth data to correlate among the plurality of data to determine if the data corresponds to a common object. Each of these data streams may be received from an off-board source via datalink or generated by an onboard simulation data source. The system correlates data received from an onboard source with data received from an off-board source to present the best available training scenario to the operator.

Abstract: A present novel and non-trivial system and methods for exacting terrain elevation data contained in a plurality of terrain elevation databases or data sets, combining the terrain elevation data contained in each terrain elevation data set to produce a single, combined terrain database of a common resolution. A system is disclosed that could provide a processor with terrain elevation data from a plurality of terrain elevations data sets having differing resolution and accuracy parameters, a per-point error metric data from a plurality of error metric data sets, and a common resolution parameter. A method is disclosed which for combining terrain elevation data sets having difference resolutions into a single, combined terrain elevation data set having a common resolution utilizing a per-point error metric data from a plurality of error metric data sets.

Abstract: The present invention is directed to a method of positioning perspective terrain on a SVS (Synthetic Vision System) based on a navigation solution, the vertical component of which is calculated utilizing a terrain database and sensing unit (which provides height above terrain). The terrain database provides elevation of terrain above MSL. A sensor, such as a GNSS sensor, may be utilized to calculate the navigation solution. In alternative embodiments, the navigation solution is calculated differently based upon the phase of flight. In one, the vertical component calculation utilizes the sensing unit at or below the sensing unit's rated altitude. In another, vertical component calculation blends the sensing unit with the sensor. The blending may be based upon percentages based upon altitude or utilize filtering such as Kalman filtering. The present invention is particularly advantageous for close to ground operations, insuring perspective terrain will stay consistent with the real world.

Abstract: A novel and non-trivial system and methods for displaying partial images and non-overlapping images acquired by vision systems representing scene is disclosed. A system is disclosed for displaying partial images and shared, non-overlapping images on a display comprises a forward-looking imaging device system, an image system, a terrain rendering processor, and an indicating system. The terrain rendering processor determines, based on visibility data, which part of an image of one system will be displayed. A method is disclosed for displaying a partial image on a display unit. A terrain rendering processor determines acceptable and unacceptable visibility data based on contrast data of first image data, and based on such determination, presents image data corresponding to unacceptable data to the indicating system for presentation on a display unit. A second method is disclosed for displaying two images on a display unit of an aircraft.

Abstract: A method of increasing situational awareness of terrain is disclosed. A representation of a terrain feature is generated from a source of stored data. A distance from a reference point to the terrain feature is determined. The representation of the terrain feature is attenuated if the distance from the reference point to the terrain feature is within a predetermined range. The representation of the terrain feature is displayed.
