A system operating in a dead reckoning mode accumulates relative yaw measurements, i.e., measurements of rotation about a z-axis, made by one or more over mechanization update intervals and produces dead reckoning mechanization update values. The system accumulates the values over a turn rate accumulation period, calculates a yaw rate and determines if the yaw rate exceeds a turn rate threshold. If so, the system directs an INS filter to perform a zero yaw rate update at the start of a next mechanization update interval, to correct for the z-axis drift errors of the gyroscopes based on the sensed rotation in the relative yaw measurements over the previous mechanization update interval. The system then sets the z-axis drift errors to zero. If the system determines that the yaw rate exceeds the turn rate threshold, the zero yaw rate update is not performed at the start of the next mechanization update interval.

A system and method for telecom inventory management are provided. The method includes obtaining street-view images of a geographical area having telecom assets. The telecom assets are associated with corresponding GPS location coordinates. An object recognition model is applied to the street-view images to detect the telecom assets therein. Detecting the telecom assets includes associating the telecom assets with corresponding asset labels. A real-world location of the telecom assets is estimated in the geographical area by applying triangulation method on a set of multi-view images selected from the street-view images. The set of multi-view images are captured from a plurality of consecutive locations in vicinity of the telecom asset in the geographical area. The GPS location coordinates of the telecom assets are validated based at least on the estimated real-world location.

A system for monitoring marine vessels using a satellite network may include a plurality of satellite payloads to be carried by respective satellites. Each satellite payload may include a communications interface configured to communicate via the satellite network, a radio frequency (RF) transceiver configured to communicate with the plurality of marine vessels, and a controller cooperating with the communications interface and the RF transceiver. The controller may be configured to obtain automatic identification system (AIS) data including vessel position and call sign information via the RF transceiver, and communicate the AIS system data via the communications interface. The system may further include a terrestrial station configured to receive the AIS system data, receive social media data, and determine expected passenger lists for the marine vessels based upon the AIS data and social media data.

A method for navigating an aerial vehicle from a first location to a second location, wherein the aerial vehicle having a localization system, the method including guiding the aerial vehicle according to a ground navigation map from the first location to the second location.

A beamforming device is provided. The beamforming device comprises: a beam deriving unit for deriving, among multiple reception beams, a first reception beam receiving, from a terminal, the first largest reception signal and a second reception beam receiving, from the terminal, the second largest reception signal; and a control unit for estimating the direction of the terminal on the basis of a ratio value between the size of the reception signal received through the first reception beam and the size of the reception signal received through the second reception beam.

The invention relates to a method of automated spatial worksite referencing of a networked electronic measuring device, which has awareness of a rough location information of itself at a worksite location. It does so with querying a database for construction plan information about the rough location and its vicinity and about an actual work progress. Thereof an actual-state nominal spatial information at the rough location and its vicinity is computed. According to the invention, an automatically determining of a fine location information of the networked electronic measuring device at the worksite location, is done by at least one iteration of: automatically determining a measurement point in the vicinity and measuring the measurement point by the networked electronic measuring devices measurement functionality, and then automatically assimilating the measurement point to the actual-state nominal spatial information and thereby determining the fine location information.

When a desired level of ambiguity and/or accuracy of the determined fine location is not reached, do another iteration with another additional measurement point, or else, automatically derive the fine location information as spatial reference of the networked electronic measuring device with respect to the worksite location.
