Abstract: A jobsite computer network has a local server connectable to a remote server via the internet, a network access transceiver connected to the local server, and a wireless device in wireless communication with the network access transceiver. The network access transceiver receives a message from the wireless device and sends a message to the local server. The local server utilizes information from the message to determine the location of the wireless device. The network access transceiver and/or the wireless device generate data which is sent to the remote server.

Abstract: An augmented-reality device is aligned with an environment using a correction source. A position of a reflector (or other device that is part of a surveying system) coupled with a surveying rod is measured in relation to a correction. A position of a visual design, which is coupled with the surveying rod, is measured in relation to an augmented-reality device, based on an image of the visual design acquired by the augmented-reality device. A coordinate system of the augmented-reality device is aligned with the environment based on the position of the reflector in relation to the correction source, the position of the visual design in relation to the augmented-reality device, and an offset between the reflector and visual design.

Abstract: Systems and methods for determining user equipment (UE) locations within a wireless network using reference signals of the wireless network are described. The disclosed systems and methods utilize a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with two or more antennas of the wireless system. Based on received reference signal parameters the reference signal within the signals from each receive channel among the receive channels is identified. Based on the identified reference signal from each receive channel, an angle of arrival between a baseline of the two or more antennas and incident energy from the UE to the two or more antennas is determined. That angle of arrival is then used to calculate the location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival.

Abstract: In one embodiment, a technique is provided for wireless position determination wherein locations of Wi-Fi access points included in a collaborative database are both consumed to estimate the position of a wireless computing device and updated based on the position of the wireless computing device. Using the collaborative database, a geographic location of each one or more first Wi-Fi access points in signal reception range of the wireless computing device is determined based on a unique or semi-unique identification of each first Wi-Fi access point. A wireless positioning system estimates a position of the wireless computing device based on the geographic location of each of the one or more first Wi-Fi access points. It may be determined that a Wi-Fi access point of one or more second Wi-Fi access points in signal reception range of the wireless computing device is a new Wi-Fi access point whose geographic location is not contained in the collaborative database. The collaborative database is updated to include the geographic location of the new Wi-Fi access point based, at least in part, on the position of the wireless computing device.

Abstract: In a method for determining orientation of an object, raw image data of the sky is recorded using a sky polarimeter. One or more of Stokes parameters (S0, S1, S2), degree of linear polarization (DoLP), and angle of polarization (AoP) are calculated from the image data to produce a set of processed images. Last known position and time data of the object are obtained, and a known Sun azimuth and elevation are calculated using the last known position and time data. Roll and pitch of the object are found, and the roll and pitch data are used to find a zenith in the processed images. The yaw/heading of the object is determined using the difference between a polarization angle at the zenith and a calculated Sun azimuth.

Abstract: Systems and techniques for time-of-flight (ToF) location determination with unmanaged WLAN are described herein. Information for ToF measurements may be received. The ToF measurements may be performed with a plurality of WLAN access points (APs), including transmitting an initiator message from the SET (e.g., navigation device) to the plurality of WLAN APs. Results for the ToF measurements may be gathered. The gathered results may be communicated to a position calculator to calculate a position of the SET.
