  • Patent number: 8972188
    Abstract: An end-user can input a correction to a map error, directly on the device. The device is then able to use the correction without external processing of the correction. Hence, it is no longer necessary for an end-user to simply report errors to the map vendor over a web link, then wait for that map vendor to verify the error, update its maps and finally supply the end-user with updates—a cycle that can take months and sometimes years to complete. Instead, the navigation device can use the correction immediately. End-users can also share corrections with other end-users and also with a shared remote server that aggregates, validates and distributes correction.

  • Patent number: 8924054
    Abstract: Systems and methods are for orienting a marine vessel having a marine propulsion device. A control circuit controls operation of the marine propulsion device. A user input device inputs to the control circuit a user-desired global position and a user-desired heading of the marine vessel. The control circuit calculates a position difference between the user-desired global position and an actual global position of the marine vessel and controls the marine propulsion device to minimize the position difference. The control circuit controls the marine propulsion device to orient an actual heading of the marine vessel towards the user-desired global position when the position difference is greater than a threshold. When the position difference is less than the threshold, the control circuit controls the marine propulsion device to minimize a difference between the actual heading and the user-desired heading while minimizing the position difference.

    Abstract: A method for adaptive driver guidance for navigation and location-based services. A navigation system onboard a vehicle records errors, including both system errors and user errors, where the errors can be detected by missed turns, re-routing, and similar events. The error data is transmitted to a central server, where the data is analyzed to determine patterns of errors, both for an individual driver and across many drivers. Roadway locations which frequently experience driver navigational errors have the error type integrated as a route feature, and future navigational guidance is adapted to improve driver performance. Adaptations can include increased or decreased frequency, detail, timing and location of navigational instructions. Individual driver guidance can also be adapted based on the driver's tendency to make errors in response to specific guidance instructions. Adaptation of guidance for location-based services is also provided.

  • Patent number: 8370028
    Abstract: A GPS sensor senses a current position of a vehicle. A map database stores map data. A controller obtains road information of a road ahead of the vehicle from the map data based on the sensed current position of the vehicle. Then, the controller measures a distance from the vehicle to a predetermined object, which serves as a sensing subject, on the road when the obtained road information is predetermined road information. Then, the controller outputs the measured distance as control information of the vehicle.

  • Patent number: 8352186
    Abstract: An efficient route-defining method includes determining a route to a destination. The exemplary method also includes determining a wireless device to server connection type and assigning a tolerance in accordance with a connection type. The tolerance is usable to determine if a vehicle is off-route, and the tolerance is increased or decreased inversely corresponding to the speed of the connection type. According to the illustrative method, the assigned tolerance is used to determine points defining the route, such that the roads comprising the route are within a bounded area. The bounded area may be defined by the tolerance in conjunction with a plurality of lines connecting successive points along the route. Finally, the method includes delivering the determined points to a vehicle computing system in communication with the server.

  • Patent number: 8346469
    Abstract: A method and apparatus for determining protection levels in a satellite navigation system includes the following steps: (1) determining an integrity risk at the alert limit for a plurality of application situations—for example, starting from approaches in category I (Category I precision approach) up to the operation “oceanic enroute;” (2) determining an interval of the alert limits between the largest set of alert limits which produces too high an integrity risk, and the smallest set of alert limits which produces an acceptable integrity risk; and (3) carrying out an interval nesting for the interval of the alert limits that was determined in the previous step, the integrity risk between the horizontal and the vertical being divided in the same way as it is obtained from the relationship between these integrity risks in the largest set of alert limits.

  • Patent number: 8301377
    Abstract: A novel Parametric Systematic Error Correction (ParSEC) system is disclosed which provides improved system accuracy for image navigation and registration (INR). This system may be employed in any suitable imaging system and, more specifically, to all imaging systems that exhibit systematic distortion. The ParSEC system may be employed to any such system regardless of sensing type (remote or in situ) or imaging media (photon or charged particle) and is further applicable to corrected imaging of any celestial body currently detectable to remove distortion and systematic error from the imaging system employed. The ParSEC system of the instant invention comprises a software algorithm that generates at least about 12 correction coefficients for each of the INR system measurements such as stars, visible landmarks, infrared (IR) landmarks and earth edges.

  • Patent number: 8195393
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, are disclosed for track simplification and correction. In one aspect, a track data set having track points defining a course can be accessed and inaccurate track points and incorrect track points can be identified, wherein identifying inaccurate track points includes comparing, for one or more of the track points, a dilution of precision (DOP) value associated with the track point to a DOP threshold, and identifying incorrect track points includes performing an error correction process. Also, a corrected track can be generated by removing identified inaccurate track points and incorrect track points from the track data set. Further, identifying an inaccurate track point can include determining that the DOP value associated with the track point exceeds the DOP threshold. Additionally, the DOP threshold can be specified by user input.
