摘要： Methods, systems, and computer programs are presented for cloud-offloaded position calculation with on-device acquisition. One method includes operations for collecting raw global positioning system (GPS) signals for a set of positions, and storing in memory the raw GPS signals. The method further includes processing the raw GPS signals in batch mode at the computing device to obtain acquisition data for the positions, where the processing includes identifying tasks for parallel processing by a graphics processing unit (GPU), performing, by the GPU, the tasks in parallel by assigning each of the tasks to a core processor within the GPU, and combining results from performing the tasks to obtain the acquisition data. Additionally, the method includes an operation for transmitting the acquisition data to a server for calculating locations for the set positions at the server, the server storing the locations and making the locations available for location-tracking applications.

摘要： Methods and systems are disclosed for providing location services for user equipment (UE) devices in a radio access network (RAN) such as a Fifth Generation (5G) RAN. Location services may be supported by separate positioning domains that may include a Device to Device domain, a RAN domain and a core network (CN) domain. The RAN domain may include a location server function (LSF) that may support positioning services autonomously within the RAN or in collaboration with a D2D or CN domain. The CN domain may include a location server (LS) that may support control plane and/or user plane location. The RAN domain may enable high volume and low latency location service whereas the CN domain may enable high accuracy service and services for external clients.

摘要： Methods and apparatus provide for positioning of a rover antenna from GNSS data derived from multi-frequency signals and correction data derived from a network of reference stations. Rover antenna position and multi-frequency ambiguities are estimated at each epoch. An ionospheric filter models variation in ionospheric bias per satellite. A set of ionospheric carrier-phase ambiguities is estimated at least when the multi-frequency ambiguities have attained a predetermined precision. The estimated ionospheric carrier-phase ambiguities are cached. After detecting interruption of signal at the rover antenna and determining reacquisition of signals at the rover antenna, an ionospheric bias per satellite over an interruption interval is predicted. For each satellite, a cached ionospheric carrier-phase ambiguity is combined with a predicted ionospheric bias to obtain a post-interruption ionospheric ambiguity estimate. The post-interruption ionospheric ambiguity estimates are used to aid estimation of rover antenna position after signal reacquisition.

摘要： A Global Navigation Satellite System (GNSS) chipset embedded within the cellular device is accessed. The GNSS chipset calculates raw pseudoranges. The raw pseudoranges are extracted from the GNSS chipset for processing elsewhere in the cellular device outside of the GNSS chipset. A position fix is calculated based on the raw pseudoranges. At a first point in time, a first image, and at a second point in time, a second image are obtained with an image capturing device that is in a known physical relationship with the cellular device. An estimate of a distance that the cellular device moved from the first point in time to the second point in time is calculated by processing image data collected from the first point in time to the second point in time. The position fix is processed based on the estimate of the distance.

摘要： A device and a method determine a sample point specific vertical total electronic content which is the electron content along a sample point specific vertical path that extends through the center of the earth and the sample point. A first inclined total electronic content is determined and refers to the electron content along an inclined beam path. A first and a further sample point along the beam path are selected. An initial sample point specific vertical total electronic content is determined for each sample point. An increment electron content is determined and refers to the electron content of the increment associated with the sample point. A further inclined total electronic content is determined. A sample point specific conversion function is determined. The sample point specific vertical total electronic content is determined from the first inclined total electronic content and the sample point specific conversion function.
