摘要： An antenna apparatus for use in a wireless network and method of operating such an antenna apparatus are provided. A wireless network controller provides a configuration of such an antenna apparatus, a method of operating such a wireless network controller, and a resulting wireless network. The antenna apparatus comprises a directional antenna and a uniform circular antenna array. The directional antenna can be rotatably positioned about an axis with respect to a fixed mounting portion of the apparatus in dependence on wireless signals received by the antenna array. The antenna array allows the antenna apparatus to receive wireless signals isotropically and thus to accurately monitor the wireless signal environment in which it finds itself. The antenna apparatus can thus monitor and characterise incoming signals, both from external interference sources and from other network nodes, and the directional antenna can then be positioned in rotation to improve the network throughput.

摘要： A construction machine includes: a work device attached to a machine body in a raiseable and lowerable manner; an antenna that is attached to the machine body and receives positioning signals from satellites; a machine body IMU that senses information on a posture and motion of the machine body; an IMU that senses information on a posture of the work device; and a computing device that computes posture information indicating the postures of the machine body and the work device. The computing device performs positioning computation to compute a position of the machine body and a variance value thereof based on the positioning signals received by the antenna, subjects the position as a result of the positioning computation to first smoothing processing that is to increase a degree of smoothing as the variance value as a result of the positioning computation becomes larger, and computes the posture information.

摘要： A method for displaying images using an AR device. GNSS position data is received based on wireless signals received from a GNSS satellite. Based on the GNSS position data, a first GNSS point within a geospatial frame is determined within a first time range and a second GNSS point within the geospatial frame is determined within a second time range. Based on camera POS data, a first AR point within an AR frame is determined within the first time range and a second AR point within the AR frame is determined within the second time range. One of the frames is shifted such that the second GNSS point is aligned with the second AR point. An angle formed by the GNSS points and the AR points is calculated. One of the frames is rotated by the angle.

摘要： The purpose is to easily achieve verification of an integrated attitude angle based on an inertial sensor. An attitude angle calculating device may include an integrated attitude angle calculating module, a reverse-calculated value calculating module, a reference value calculating module, and a determining module. The integrated attitude angle calculating module may calculate an integrated attitude angle using an output of the inertial sensor and a positioning signal. The reverse-calculated value calculating module may reverse calculate, using the integrated attitude angle, a physical quantity obtained based on the positioning signal that is used for calculating the integrated attitude angle. The reference value calculating module may calculate a reference physical quantity corresponding to the reverse-calculated physical quantity, based on an observation value of the positioning signal. The determining module may determine whether to reset the calculation of the integrated attitude angle by using the reverse-calculated physical quantity and the reference physical quantity.

摘要： In one embodiment, a cluster application generates navigation-related data based on observations received from vehicles. In operation, the cluster application computes an oriented distance between two observed object positions based on a heading, where each observed object position is associated with a different one of two observations. The cluster application then generates a cluster that includes the two observations based on the oriented distance. Subsequently, the cluster application computes an object position that is associated with the cluster based on the two observations. The cluster application transmits the object position and at least one characteristic associated with the observations to a update application that generates an update to a road database. Because the cluster application computes the object position based on multiple observations that are likely of a single object, the object position associated with the cluster may be more reliable than the observed object positions.

摘要： The system has multiple, infrared cameras 8 adjusted to spatially detect infrared radiance in different bands of infrared light, and connected to an image processing computer that processes and combines the images, and generates video display signals for producing a video display which indicates the position of the adverse atmospheric conditions relative to the aircraft. Each of the cameras is provided with a respective filter adjusted to filter infrared light with a bandwidth corresponding to infrared bandwidth characteristics of an adverse atmospheric condition from a set of adverse atmospheric conditions. The image processing computer is adapted to identify adverse atmospheric conditions, based on threshold conditions and using the detected infrared radiance, data from a look-up table and measured parameters including information on the position and/or attitude of the aircraft. The image processing computer is further adapted to display the identified adverse atmospheric conditions as a spatial image on a display.

摘要： A method for visual inertial odometry (VIO)-aided global positioning is described. The method includes updating an extended Kalman filter (EKF) state including a current pose and a sliding window of multiple prior poses. The sliding window includes poses at a number of most recent global positioning system (GPS) time epochs. Updating the EKF includes updating an EKF covariance matrix for the prior poses and the current pose in the EKF state. The method also includes determining, at a GPS epoch, a relative displacement between each of the updated prior poses and the current pose. The method further includes determining an error covariance of each of the relative displacements based on cross-covariances between each of the updated prior poses and the current pose in the EKF covariance matrix. The method additionally includes using the relative displacements and the error covariances to fuse pseudorange measurements taken over multiple epochs.

摘要： Systems and methods for communicating in a point to multipoint (PTMP) network that includes an aerial station and a plurality of ground stations. The method includes the aerial station receiving positional information of a ground station of the plurality of the ground stations, selecting antenna elements on a phased antenna array for generating a directional beam based on the positional information, sweeping the directional beam to cover the plurality of ground stations, determining that the directional beam has a beam width sufficient to cover the plurality of ground stations and a transmit power sufficient to provide signals to the ground stations based on the sweeping of the directional beam; and establishing a radio link between the aerial station and the ground station in the plurality of ground stations.
