A vehicle position estimation device includes an external information acquisition unit for acquiring external information, a vehicle parameter acquisition unit for acquiring a vehicle parameter, a satellite positioning acquisition unit for acquiring a latitude and longitude of a self-position of the vehicle, a map data acquisition unit for acquiring map data, and a position estimation unit. The position estimation unit estimates the self-position, and includes a reliability calculation unit and a lane estimation unit. The reliability calculation unit calculates a reliability of each lane based on the external information and the map data when the vehicle is traveling on a road having multiple lanes. The reliability of each lane indicates a probability of the vehicle being traveling in the lane among the lanes. The lane estimation unit estimates a lane in which the vehicle is located by using the reliability calculated by the reliability calculation unit.

A device may receive, from a vehicle device, a geographical (e.g., GNSS) location of a vehicle, and may utilize the GNSS location as a determined location of the vehicle when the GNSS location satisfies a first threshold. The device may receive, from the vehicle device, an image identifying reference points associated with the vehicle, and may process the image, with a VPS, to calculate a VPS location of the vehicle. The device may utilize the GNSS location of the vehicle as the determined location when the VPS location fails to satisfy a second threshold, and may calculate, when the VPS location of the vehicle satisfies the second threshold, coordinate sets based on groups of coordinate combinations from the GNSS location and the VPS location. The device may process the coordinate sets, with a model, to determine the determined location, and may perform actions based on the determined location.

Global positioning system (GPS) receivers, along with a user device with a camera, can be used to determine an elevation of a point of interest on or within a structure. The user device and a first GPS receiver can be located somewhere outside the structure from which the structure is clearly visible. A second GPS receiver can be located on, within, or near the structure. The user device receives location data from both GPS receivers and calculates a distance between the two. The user device then takes a digital photograph in which structure is visible and notes the photo capture angle. The user device then calculates the elevation of the point of interest trigonometrically using the calculated GPS distance and the photo angle. The user device can then automatically insert this information into associated documentation and transmit the same.

A flight emulation system receives global positioning system (GPS) data into one or more EGIs (embedded GPS/inertial navigation system (INS)) or GPS receivers from a GPS emulator. The GPS data are based on a pre-defined flight trajectory plan of an aircraft. The system calculates real-time positional, orientational, and inertial emulation data using outputs of the EGIs or GPS receivers and platform-specific, flight dynamics data, and then transmits the real-time positional, orientational, and inertial emulation data to one or more subsystems associated with the aircraft for use by operations of the one or more subsystems.

Position enhancement for vehicle positioning is provided. Vehicle-to-everything (V2X) messages are received from a roadside unit (RSU) to an onboard unit (OBU) of a vehicle via a transceiver of the vehicle, the V2X messages indicating a location of the RSU. Image sensors of the vehicle are utilized to capture sensor data of the RSU. A current position of the vehicle is updated to a corrected current position of the vehicle based the RSU as shown in the sensor data and the location of the RSU indicated in the V2X messages.
