Abstract:
The cellular device accesses a GPS/GNSS chipset embedded within the cellular device. The GPS/GNSS chipset calculates pseudorange information for use by the GPS/GNSS chipset. The cellular device extracts the pseudorange information from the GPS/GNSS chipset for use elsewhere in the cellular device outside of the GPS/GNSS chipset.
Abstract:
Examples are described relating to control of a geographical position of a mobile unit in time. In one example, a dispatch control system is provided. The dispatch control system has a data store with records of previously-attended geographical positions. These records indicate at least a duration of attendance. The dispatch control system is arranged to calculate one or more stochastic characteristics for the durations of attendance based on the records stored in the data store, the one or more measured stochastic characteristics being representative of a variability of the durations of attendance at said past geographical positions. It is also arranged to generate data indicative of an order of attendance for a mobile unit based on travel and estimated durations of attendance. This data is re-ordered and volatility metrics for each set of modified data are determined. The set of volatility metrics is used to modify the data indicative of an order of attendance for a mobile unit. In one case, volatile events are re-ordered after critical events to reduce uncertainty. The dispatch control system is configured to transmit, to the mobile unit, data indicative of geographical positions corresponding to said modified generated data. The transmitted data is for use in generating routing instructions, which, when executed by a processor associated with the mobile unit, cause navigation of the mobile unit between physical locations associated with the geographical positions corresponding to said modified generated data.
Abstract:
A method for displaying image data from a plurality of images on a display monitor, where at least some of the images are acquired from different locations, includes displaying the image data from the images on the display monitor. The image data may be displayed from a perspective center associated with the different locations from which the images are acquired. A primary image is determined based on a portion of the image data from the primary image that is displayed on the display monitor compared to portions of the image data from other images that are displayed on the display monitor. Thereafter, the image data on the display monitor is displayed from a perspective center of the primary image. A stacking order of the plurality of images is arranged so that the primary image is on top.
Abstract:
A method of implementing fast GNSS convergence by relative positioning is disclosed. A GNSS receiver which is coupled with a mobile machine is shut down. The GNSS receiver is in a converged state at shut down. A movement sensor is monitored to determine if net movement of a GNSS antenna coupled with the mobile machine exceeds a threshold net movement parameter while the GNSS receiver is shut down. Upon power up of the GNSS receiver, a shorter convergence algorithm is initiated in response to determining that the threshold net movement parameter has not been exceeded. The shorter convergence algorithm is also initiated upon power up of the GNSS receiver in response to determining that the threshold net movement parameter has been exceeded but information from the movement sensor has been used to update the location of the GNSS receiver since said shut down.
Abstract:
A verified antispoofing navigation apparatus is provided. The apparatus comprises: a primary navigation receiver configured to provide a set of primary measurements related to positioning of a mobile platform; a supplemental navigation device configured to provide a set of supplemental measurements related to positioning of the mobile platform; an identity monitoring device configured to verify an identity of a driver of the mobile platform; and a verification and authentication navigation processor configured to verify authenticity of the set of primary measurements provided by the primary navigation receiver by using the set of supplemental measurements provided by the supplemental navigation device. The verified antispoofing navigation apparatus further comprises: a driver authentication navigation processor configured to provide the driving and rest times of the driver to relevant authorities.
Abstract:
A method includes providing a processor, obtaining an image of a scene including one or more objects, and presenting, using the processor, the image of the scene to a user. The method also includes receiving a geometry type associated with one of the one or more objects, receiving a set of inputs from the user related to the one of the one or more objects, and determining, using the processor, a centerline of the one of the one or more objects. The method further includes measuring, using the processor and inputs from the user, two or more coordinate positions along the centerline, receiving a dimension associated with the one of the one or more objects, and creating, using the processor, a 3D solid model using the geometry type, the dimension, the set of inputs, and the two or more coordinate positions.
Abstract:
A method for monitoring movement of a surface using ground based radar interferometry measurements includes identifying micro climates on the surface and determining boundaries of the micro climates on the surface. One or more first sensors are arranged at a measurement site for measuring first atmospheric conditions at the measurement site. One or more additional sensors are arranged in each of the micro climates for measuring atmospheric conditions in the micro climates. An atmospheric correction is determined for each of the micro climates. The atmospheric correction for each micro climate is based on the first atmospheric conditions at the measurement site and the atmospheric conditions at the micro climate. The ground based radar interferometry measurements are performed across the surface, and the ground based radar interferometry measurements within the boundary of each micro climate are corrected using the atmospheric correction for the micro climate.
Abstract:
A radio frequency identification (RFID) tower crane load locator and sway indicator includes: a plurality of RFID tags at different locations on or around the crane; at least two RFID readers at different locations on the crane; a navigation satellite system (NSS) position receiver; and a load information interface. The RFID readers comprise a range determiner to provide range measurements between each of the RFID readers and each of the RFID tags. The sway determiner is coupled with a hook block of the crane. The NSS position receiver is coupled with the crane and comprises an antenna fixedly coupled with approximately the front of a jib of the crane. The load information interface combines information from range measurements, the sway determiner and the NSS position receiver to generate location and sway information of the load with respect to the crane and provide this information in a user accessible format.
Abstract:
Novel tools and techniques for generating survey data about a survey site. Aerial photography of at least part of the survey site can be analyzed using photogrammetric techniques. In some cases, an unmanned aerial system can be used to collect site imagery. The use of a UAS can reduce the fiscal and chronological cost of a survey, compared to the use of other types aerial imagery and/or conventional terrestrial surveying techniques used alone.
Abstract:
A method for establishing an approximate number of persons in an area of interest comprises providing a request to one or more communications providers that cover an area of interest. The request is for a listing of any mobile communication devices located within the area of interest. The listing of any mobile communication devices located within the area of interest is utilized to establish an approximate number of persons in the area of interest.
