    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 vehicle controller includes at least one input configured to receive sensor signals from a plurality of sensors configured to determine vehicle dynamic information and at least one input configured to receive sensor signals from a plurality of sensors configured to determine external vehicle information Included in the vehicle controller is a memory and a processor. The memory stores instructions for executing a vehicle positioning system and a driver assistance system using the controller. An output is configured to output a safe to pass condition in response to the controller determining an available vehicle power meets or exceeds an estimated power requirement for a passing operation.

    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.
