Patent number: 8271191Abstract: Methods and systems for determining reliability of Global Positioning System (GPS) ground speed. An example system receives GPS track information and GPS ground speed, determines a change in GPS track information and determines reliability of the GPS ground speed based on the determined change in GPS track information relative to the GPS ground speed. The system sets a GPS ground speed based on the determined reliability. A GPS ground speed output is set to zero, if the GPS ground speed is determined unreliable and the GPS ground speed output is set to the GPS ground speed, if the GPS ground speed is determined reliable. The system sends the GPS ground speed output to a Runway Awareness and Advisory System (RAAS). Also, the system sets the GPS ground speed output to zero, if a received GPS ground speed validity signal or a received GPS track validity signal indicate invalid.Type: GrantFiled: June 26, 2006Date of Patent: September 18, 2012Assignee: Honeywell International Inc.Inventors: Yasuo Ishihara, Kevin J Conner, Steve C.

Patent number: 8259007Abstract: A partitioning system includes a decomposer module, a supply and cell commonality computation module, a network structure setup module, a seed selection module, an optimization setup module, a solver module, and a boundary creation module. A network structure is created by connecting each cell to each of its neighboring cells using bi-directional arcs. Each bi-directional arc is assigned a flow value and a cell commonality metric. The optimization program is solved to determine the flow value for each bi-directional arc and to determine a plurality of open seeds. Each determined seed represents one partition. Partition boundaries are created by grouping cells when they are connected to each other via one of the updated set of bi-directional arcs into cell clusters. Cells within cell clusters are merged to create the predetermined number of contiguous partitions.Type: GrantFiled: July 15, 2010Date of Patent: September 4, 2012Assignee: Metron Aviation, Inc.Inventor: Arash Yousefi

Patent number: 8237607Abstract: A method and system for coordinating air-to-air tracking and air-to-ground tracking for an airborne tracked target that is landing or performing an airdrop. Air-to-air tracking data is analyzed to detect if the tracked target is landing, and a predicted landing location is computed. An air-to-ground sensor is activated, via a separate air-to-ground tracking module or via a mode change, and the air-to-ground tracking is initiated at the predicted landing location of a detected target. Both automated and manually-assisted air-to-ground activation are supported.Type: GrantFiled: December 25, 2008Date of Patent: August 7, 2012Assignee: Elta Systems Ltd.Inventor: Yahali Merhav

Patent number: 8190353Abstract: A computer based method, system and computer program product to assign a quality metric to an airspace design and optionally to compare it against design metrics, to determine a comparative quality metric. Factors contributing to quality of the airspace sector design are identified via user input and quantified to calculate a quality metric for the airspace sector design as a function of the quantified factors. Categories for each of the identified factors, and parameters for each of the identified categories are also identified via user input. Each parameter has an associated weight and a range of thresholds with associated multipliers. An associated multiplier from the range of thresholds for each identified parameter is also identified. The identified multiplier is multiplied with the associated weight for each identified parameter. The products for each identified parameter are then summed to obtain a quality metric.Type: GrantFiled: August 28, 2006Date of Patent: May 29, 2012Assignee: The MITRE CorporationInventors: Michael J.
