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.
