Abstract: Systems and techniques are described for processing one or more maps. For example, a method can include obtaining a first map of an environment in which the computing device is located and obtaining a second map of the environment based on sensor data from one or more sensors. The method can include comparing first one or more elements of the first map and second one or more elements of the second map. Each respective element of the first one or more elements corresponds to a respective element of the second one or more elements. The method can further include determining whether to use the first map or the second map for at least one navigation function based on comparing the first one or more elements of the first map with the second one or more elements of the second map.

Abstract: Techniques provided herein are directed toward tracking lateral and longitudinal offsets, which can include positioning errors of an initial position estimate as well as inconsistencies between the map and global frames. Tracking lateral and longitudinal offsets in this manner have been shown to help increase the accuracy of subsequent position estimates of a position estimation system for vehicle that uses an initial position estimate based on GNSS and VIO, with error correction based on location data for observed visual features obtained from a map.

Abstract: A method for vehicle positioning may include determining a first 6 degrees of freedom (6-DOF) pose of a vehicle, wherein the first 6-DOF pose may comprise a first altitude and one or more first rotational parameters indicative of a first orientation of the vehicle relative to a reference frame. A lane plane associated with a roadway being travelled by the vehicle may be determined based on the first 6-DOF pose and lane-boundary marker locations of lane-boundary markers on the roadway. For each lane-boundary marker, the corresponding lane-boundary marker location may be determined from a map, which may be based on the reference frame. A corrected altitude of the vehicle may then be determined based on the lane plane. A corrected 6-DOF pose of the vehicle may be determined based on the corrected altitude of the vehicle, the first 6-DOF pose, and an axis normal to the lane plane.

Abstract: A method for position determination based on carrier-phase measurements is disclosed. The method comprises receiving one or more downlink signals transmitted from a base station (BS) during a downlink period, wherein the downlink signals are modulated using a downlink carrier wave, measuring, during the downlink period, a first carrier phase associated with the downlink carrier wave, estimating, during an uplink period subsequent to the downlink period, an integer ambiguity (IA) change, and measuring, during a later downlink period subsequent to the uplink period, a second carrier phase based on the resolved first carrier phase and the estimated IA change.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The device may receive a signal on each of N channels from another device. The N channels may include a first channel. The device may determine a frequency response of each of the N channels based on the received signals. The device may transform, from a frequency domain to a time domain, the N frequency responses in order to generate a transformed signal. The frequency response of an nth channel of the N channels may be adjusted by a channel offset of the nth channel with respect to the first channel for n being each integer from 2 to N. The device may then estimate the channel offset for each of the N channels other than the first channel based on the transformed signal.

Abstract: Techniques provided herein are directed toward virtually extending an updated set of output positions of a mobile device determined by a VIO by combining a current set of VIO output positions with one or more previous sets of VIO output positions in such a way that ensure all outputs positions among the various combined sets of output positions are consistent. The combined sets can be used for accurate position determination of the mobile device. Moreover, the position determination further may be based on GNSS measurements.
