Abstract: An illustrative example embodiment of a system for determining heading direction information includes a plurality of detectors in a predetermined detector arrangement. The detectors are respectively configured to detect at least one satellite. At least one processor is configured to determine a spatial relationship between at least one characteristic of the detector arrangement and a single satellite detected by each of the detectors. The processor is configured to determine the spatial relationship at each of a plurality of times when each of the detectors detects the single satellite. The processor is configured to determine heading direction information based on a difference between the determined spatial relationships.

Abstract: A dead-reckoning guidance system determines a vehicle-speed of the host-vehicle based on wheel-signals from the one or more wheel-sensors; determines a distance-traveled by the host-vehicle during a time-interval since prior-coordinates of the host-vehicle were determined; determines a heading-traveled of the host-vehicle during the time-interval since the prior-coordinates of the host-vehicle were determined; determines present-coordinates of the host-vehicle based on the distance-traveled and the heading-traveled; determines when the vehicle-speed is greater than a speed-threshold; determines when the heading-traveled differs from a cardinal-direction by both greater than a noise-threshold and less than an angle-threshold; and in response to a determination that both the vehicle-speed is greater than the speed-threshold and that the heading-traveled differs from the cardinal-direction by both greater than the noise-threshold and less than the angle-threshold, determines a coordinate-correction to apply to the present-coordinates, said coordinate-correction determined in accordance with the distance-traveled and the cardinal-direction.

Abstract: A dual-antenna positioning system includes a first GNSS antenna/receiver, a second GNSS antenna/receiver, and a GNSS processor system. The first GNSS antenna/receiver is located at a first position and calculates a first pseudo-range based on a received GNSS signal. The second GNSS antenna/receiver is located at a second position a known distance from the first GNSS antenna/receiver, wherein the second GNSS antenna/receiver calculates a second pseudo-range based on a received GNSS signal. The GNSS processor system configured to receive the first pseudo-range and the second pseudo-range, wherein in response to the GNSS processor system identifying one of the first and second pseudo-ranges as erroneous and one of the first and second pseudo-ranges as valid, the GNSS processing system calculates a corrected pseudo-range and utilizes the corrected pseudo-range and the valid pseudo-range to determine GNSS position fix estimates for the first GNSS antenna/receiver and the second GNSS antenna/receiver.

Abstract: A system for generating a 3D reflective surface map includes a positioning system, one or more antennas co-located with the positioning system, and a processing system. The positioning system calculates a position estimate. The one or more antennas co-located with the positioning system are configured to receive at least one reflected global navigation satellite system (GNSS) signal associated with a respective GNSS satellite and wherein a pseudo-range to the GNSS satellite is determined based on the reflected GNSS signal. The processing system is configured to receive the position estimate and the pseudo-ranges calculated with respect to each reflected GNSS signal, wherein the processing system maps a reflective surface based on the calculated pseudo-range provided by the reflected GNSS signals, the position estimate, angle-of-arrival of each reflected GNSS signal, and known satellite location of each respective GNSS satellite.

Abstract: A navigation device is associated with a navigable physical property for which navigation instructions or data are not publicly accessible by a vehicle navigation system. The navigation device includes a transceiver unit, and a navigation unit. The transceiver unit is configured to communicatively couple with a vehicle. The navigation unit is associated with the navigable physical property. The navigation unit is configured to determine, based on communications with the vehicle via the transceiver unit, whether the vehicle should be enabled to navigate the navigable physical property. In accordance with the determination that the vehicle should be enabled to navigate the navigable physical property, the navigation unit communicates instructions and data that enable the vehicle to navigate the navigable physical property.
