Abstract: This document describes vehicle localization using map and vision data. For example, this document describes a localization system that obtains a map centerline point and a vision centerline point of a lane of a roadway. The localization system also obtains the position of the vehicle. The localization system can then compare the map centerline point and the vision centerline point to generate a lateral and a longitudinal correction relative to the vehicle's position. The lateral and longitudinal corrections are used to generate a corrected position. In this way, the described localization system can provide accurate vehicle localization that addresses potential drift caused by lapsed or inaccurate positioning data and allows for the operation of assisted-driving and autonomous-driving systems at higher speeds and on roadways with tighter curves.

Abstract: A system for generating satellite positioning corrections includes a global correction module that generates a set of global pre-corrections based on modeling of global positioning error, a set of local correction modules that, for each local correction module of the set, takes input from a unique reference source and generates a set of local pre-corrections based on modeling of local positioning error; and a correction generator that generates a positioning correction from the set of global pre-corrections and the sets of local pre-corrections to correct a position of the mobile receiver.

Abstract: A method performed by a target device to obtain positioning assistance data from a location server is provided. The target device and the location server are operating in a wireless communications network. The target device transmits a request to the location server. The request is a request for positioning assistance data and provides first logical position information. The target device obtains positioning assistance data from the location server. The positioning assistance data is based on the first logical position information. When being associated with a second logical position, the target device transmits a request to the location server. The request requests for positioning assistance data and provides second logical position information. The target device obtains positioning assistance data from the location server. The positioning assistance data is based on the second logical position information.

Abstract: This application relates to a data signal processing method. In one aspect, the method includes receiving a data signal from at least one global navigation satellite system (GNSS) satellite and obtaining a pseudo-range of the at least one GNSS satellite by using the data signal. The method may also include obtaining a range-acceleration based on the pseudo-range. The method may further include applying, to the data signal, a variance obtained by assigning a weight according to a noise model to the range-acceleration.

Abstract: A method for determining a position of a vehicle. The method has a step of carrying out self-locating of the vehicle using a locating device of the vehicle in order to generate a provisional position of the vehicle. The method also has a step of reading in a position signal, the position signal representing a position of another vehicle. Moreover, the method has a step of ascertaining a relative position of the vehicle relative to the other vehicle with the aid of the position signal in order to determine the position of the vehicle using the self-locating and the relative position.

Abstract: Accurate position capability can be quickly provided using a Wireless Local Area Network (WLAN). When associated with a WLAN, a wireless device can quickly determine its relative and/or coordinate position based on information provided by an access point in the WLAN. Before a wireless device disassociates with the access point, the WLAN can periodically provide time, location, and decoded GPS data to the wireless device. In this manner, the wireless device can significantly reduce the time to acquire the necessary GPS satellite data (i.e. on the order if seconds instead of minutes) to determine its coordinate position.

Abstract: A mobile object according to the present technology includes a sensor, a map location estimation unit, a relative location estimation unit, a relative location estimation unit, a GNSS reception unit, and an absolute location estimation unit. The sensor acquires surrounding information. The map location estimation unit estimates a self location in a local map on the basis of an output of the sensor. The GNSS reception unit receives global navigation satellite system (GNSS) positioning information using a first carrier phase distance. The absolute location estimation unit estimates a self absolute location on the basis of the GNSS positioning information using the first carrier phase distance, GNSS positioning information using a second carrier phase distance, and a relative location, the GNSS positioning information using the second carrier phase distance being received by another mobile object.
