Abstract: The present invention is a method for dynamically determining a blended navigation solution for a mobile platform (ex.—aircraft) via a receiver implemented on-board the platform. In the method disclosed herein, the receiver concurrently utilizes data from satellite signals obtained from a plurality of independent satellite constellations in calculating its (the receiver's) navigation solution (ex.—Position, Velocity, Time (PVT) solution), thereby overcoming weaknesses inherent in currently available systems and methods, which rely on only a single satellite constellation.

Abstract: When preparing a representation of map display information for use by a navigation device, a set of source map data (600) is subject to a similarity analysis step (601) to try to identify elements in the source map data (600) that are similar in terms of their shape and/or their appearance when displayed. A classification and transformation parameter generation step (602) then classifies elements in the map into groups of similar elements as determined by the similarity analysis (601) and also determines the parameters and conditions under which the identified map elements can be considered to be similar. This is then used to generate a map database that includes a library of predefined map display elements having parametrable aspects, which map display elements can then be used to construct a desired map for display.

Abstract: A device is disclosed that is capable of determining its location using high-power with high accuracy, and using low-power with lower accuracy. By coordinating usage between the high power method and the low power, overall power consumption of the device can be significantly reduced without a significant reduction in accuracy. Such high accuracy may be achieved through the use of a GNSS unit, such a GPS receiver. In addition, the low-power alternative may be achieved using an accelerometer, together with software, hardware or firmware for extrapolating a speed based on the force measurements by the accelerometer. In this manner, the GPS receiver can be operated for only a fraction of overall use, primarily to provide adjustment data necessary to calibrate usage of the accelerometer.

Abstract: A rollover detection system is provided that comprises a device, a sensor and/or a group of sensors and a warning system for use in a vehicle to reduce or prevent the likelihood of a rollover during operation of the vehicle. The rollover detection system can provide a driver of a vehicle, information that informs the driver of the risk and imminence of a rollover and allows the driver to take corrective action to reduce the risk or imminence of a rollover. The rollover detection system can also allow for the review of information collected by a device by a driver or other individual during and after a risk of a rollover is detected.

Abstract: A tracking server receives GPS data from a location tracking device located in a vehicle. The GPS data describes a path that is representative of a pathway of the vehicle used to complete a trip from a starting location to a destination location. The tracking server identifies noisy GPS data included in the received GPS data and revises a portion of path corresponding to the noisy GPS data. The tracking server may update a map database to include one or more road segments associated with the revised portion of the path. Furthermore, the tracking server may calculate a fare for the trip based on the revised path.

Abstract: A portable navigation module and its method of operation are disclosed for seamlessly providing navigation and positioning information to a user. The module comprises: means, such as a GPS receiver, for receiving a first set of navigational information from an external source, such as satellites; and an inertial sensor unit for generating a second set of navigational information at the module. The navigational information is used by a processor programmed with a core algorithm, to identify the mode of conveyance algorithm and an orientation or misalignment algorithm. The algorithm utilizes the navigational information, aided by the mode of conveyance information and the orientation information, to produce a filtered navigation solution (which comprises position, velocity and attitude). The solution is suitably displayed, preferably on a detachable display unit.The system has the following attributes: the solution is produced seamlessly, even if one source of navigational information is temporarily out of service; the accuracy of the solution is assisted by use of the mode of conveyance and orientation information; and there is no requirement for the module to be permanently aligned with the direction of movement of the conveyance platform.
