摘要： Systems and methods are described for determining position of a receiver. The positioning system comprises a transmitter network including transmitters that broadcast positioning signals. The positioning system comprises a remote receiver that acquires and tracks the positioning signals and/or satellite signals. The satellite signals are signals of a satellite-based positioning system. A first mode of the remote receiver uses terminal-based positioning in which the remote receiver computes a position using the positioning signals and/or the satellite signals. The positioning system comprises a server coupled to the remote receiver. A second operating mode of the remote receiver comprises network-based positioning in which the server computes a position of the remote receiver from the positioning signals and/or satellite signals, where the remote receiver receives and transfers to the server the positioning signals and/or satellite signals.

摘要： In one embodiment, scanning data is received for wireless access points whose wireless signals were observed by the one or more scanning devices in a target area. For each group of scanning data that shares a common identifier of a Wi-Fi access point, a centroid of the scanning data is determined, a set of scanning data of the group that exceeds a threshold distance from the centroid is designated as having potential error, and a location of the Wi-Fi access point is calculated. The calculated location of the Wi-Fi access point for each group of scanning data is stored in a reference database. Upon receiving a request for a location of a mobile device, an identity of one or more Wi-Fi access points in range of the mobile device is determined, and the location of the mobile device is computed using calculated locations from the reference database.

摘要： The disclosed invention embodies a system and method for multi-sensor, multi-frequency, multi-constellation data integration providing integrated onboard positioning of a vehicle. Multiple correlators perform autonomous signal quality monitoring to avoid the need for external augmentation systems. The integrated method and system typically includes multi-constellation, multi-channel GNSS and may consider positioning information from one or more other positioning resources including onboard, airborne, and ground-based signals. The positioning information from these functions are used in combination to exclude an erroneous signal from consideration while providing an integrated, blended precision positioning solution with improved size, weight, power and cost characteristics. The system utilizes a plurality of positioning signals from multiple GNSS constellations on multiple channels correlated with ground-based, airborne, and onboard positioning signals to determine a hierarchy of positioning signals used in accurate positioning without the need for differential correction provided by offboard augmentation.

摘要： A pressure sensor can be implemented on a network device to minimize vertical positioning errors of the network device in an indoor environment. A reference altitude and a reference pressure associated with an access point in the indoor environment are received at the network device via a communication network. A pressure is determined at the network device in the indoor environment. An altitude of the network device associated with the pressure at the network device in the indoor environment is calculated based, at least in part, on the pressure at the network device, the reference pressure, and the reference altitude. A position of the network device in the indoor environment is determined based, at least in part, on the altitude of the navigation device and location information received from at least the access point.

摘要： A method and apparatus to utilize a set of measurements (either partial or compete) to improve the accuracy of an initial position estimate for a wireless terminal. The initial position estimate for the terminal is first obtained (e.g., based on a cell-ID or an enhanced cell-ID solution). Measurements are obtained for the terminal. The initial position estimate is then updated with the measurements to obtain a revised position estimate for the terminal. The updating may be performed by (1) deriving a measurement vector based on the initial position estimate and the measurements, (2) forming an observation matrix for the measurements, (3) determining a matrix of weights, (4) deriving a correction vector based on the measurement vector, the observation matrix, and the weight matrix, and (5) updating the initial position estimate with the correction vector.

摘要： A positioning system operates by first determining that a user is pedestrian, and then estimating a speed of the user. Having tracked a first signal from one radio transmitter whose position is known, the system attempts to detect additional signals from the one transmitter, in a search space such that the first signal and the or each additional signal are consistent with the estimated speed of the user and with one or more of the signals having been reflected off a reflector in the vicinity of the user. One or more detected additional signals from the one transmitter are then tracked, and candidate measurements, derived from the first signal and the one or more detected additional signals, are provided for use when estimating the position and/or velocity of the user.
